`TITLE: LIQUID CRYSTAL DISPLAY DRIVING DEVICE OF MATRIX
`
`STRUCTURE TYPE AND ITS DRIVING METHOD
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to a liquid crystal display driving device of matn'x
`
`structure type and its driving method, especially to a display driving device and its
`
`driving method, which can simultaneously or synchronously drive a plurality of thin
`
`film transistors to increase the response speed, wherein the source and the gate of each
`
`thin film transistor in the driving device are respectively connected with different gate
`
`lines and data lines to let the specific transistor be driven by the gate drivers and the
`
`data drivers, and the predetermined voltage for over drive or the data voltage for the
`
`present frame interval is applied to accomplish the object of increasing the response
`
`speed. The present invention can suit for the picture treatment of various liquid crystal
`
`displays, organic light emitting diode (OLED) display or plasma display panel (PDP).
`
`2. Description of the Prior Art
`
`Because the liquid crystal display possesses the advantages of low power
`
`consumption,
`
`light of weight,
`
`thin thickness, without radiation and flickering,
`
`it
`
`gradually replaces the traditional cathode ray tube (CRT) display in the display market.
`
`The liquid crystal display is chiefly used as the screen of the digital television, the
`
`computer or the notebook computer. In particular, the large sized liquid crystal display
`
`is widely used in the amusements of the life, especially in the field in which the View
`
`angle, the response speed, the color number, and the image of high quality are in great
`request.
`
`Referring to Fig.1A and 1B, they are the simple schematic views showing the
`
`internal structure of the prior liquid crystal display. Mark 10 is the display panel. The
`
`data driver 11 is installed above the display panel, which can change the data of the
`
`adjusted gray level signal into the corresponding data voltage. The image signal can
`
`be transferred to the display panel 10 through the plurality of data lines 111 connected
`
`with the data driver 11. The gate driver 12 is installed on one side of the display panel
`
`10, which can continuously provide scanning signal. The scanning signal can be
`
`transferred to the display panel 10 through the plurality of gate lines 121 connected
`
`with the gate driver 12. The data line 111 and the gate line 121 are orthogonally
`
`crossed and insulated with each other. The area enclosed in them is a pixel 13.After

`

`

`the image signal is output from the data driver 11, it will get to the source of the thin
`
`film transistor Q in the pixel 13 through the data line D], and a control signal is
`
`correspondingly output from the gate driver 12, it will get to the gate of the thin film
`
`transistor Q] through the gate line G1. The circuit in the pixel 13 will output the output
`
`voltage to drive the liquid crystal molecular corresponding to the pixel 13, and a
`
`parallel plate type of capacitor CLC (capacitor of liquid crystal) will be formed by the
`
`liquid crystal molecules between the two pieces of glass substrates in the display
`
`panel 10. Because the capacitor CLC cannot keep the voltage to the next time of
`
`renewing the frame data, so there is a storage capacitor C3 provided for the voltage of
`
`the capacitor being able to be kept to the next time of renewing the frame data.
`
`The image treatment of the display is affected by the properties of the liquid
`
`crystal molecular such as viscosity, dielectricity and elasticity etc. The brightness in
`
`the traditional CRT is displayed by the strike of the electron beam on the screen
`
`coated with phosphorescent material, but the brightness display in the liquid crystal
`
`display needs time for the liquid crystal molecular to react with the driving voltage,
`
`the time is called “response time”. Taking the normally white (NW) mode as an
`
`example, the response time can be divided to two parts:
`
`(1) The ascending response time:
`
`it is the time for the liquid crystal molecular to
`
`rotate with the application of the voltage when the brightness of the liquid crystal
`box in the liquid crystal display changes from 90% to 10%, simply called “T,”;
`and
`
`(2) The descending response time: it is the time for the liquid crystal molecular to
`
`restore without the application of the voltage when the brightness of the liquid
`crystal box changes from 10% to 90%, simply called “Tf‘”.
`
`When the display speed of the frame is above 25 frames per second, human will
`
`regard the quickly changing frames as the continuous picture. In general above 60
`
`frames per second is the display speed of the screen in the modern family amusements
`
`such as DVD films of high quality and electronic games of quick movement, in other
`
`words, the time of each frame interval is 1/60 sec=16.67ms. If the response time of
`
`the liquid crystal display is longer than the frame interval time, the phenomena of
`
`residue image or skip lattice would happen in the screen so that the quality of the
`
`image is badly affected. At present the methods for decreasing the response time of
`
`the liquid crystal display have: lowering the viscousity, reducing the gap of the liquid
`crystal box, increasing the dielectricity and the driving voltage, wherein the methods
`
`of lowering the viscosity, reducing the gap of the liquid crystal box and increasing the

`

`is
`
`dielectricity can be executed from the material and the making process of the liquid
`
`crystal and the method of increasing the driving voltage can be executed from the
`
`driving method of liquid crystal panel. The latter can further improve the response
`
`speed of the gray level in no need of largely changing the structure of the display
`
`panel. It is called “overdrive” (OD) technique, wherein the increasing voltage can be
`
`transferred to the liquid crystal panel through the driver integrated circuit (diver IC) to
`
`increase the voltage for rotating the liquid crystal so that the expected brightness of
`
`the image data can be quickly obtained and the response time can be reduced due to
`
`the quick rotation and restoration of the liquid crystal.
`
`Referring to Fig.2, the liquid crystal display has different brightness at different
`
`driving voltage. If L1 is the expected brightness of the image data and the liquid
`
`crystal molecular is driven by the present data voltage V1 to display the brightness, the
`
`brightness variation displayed by the driven liquid crystal molecular is shown as curve
`
`21 and the time for obtaining the brightness is to. An increased driving voltage V2 is
`
`provided to reduce the time for obtaining the brightness according to the brightness
`
`variation of the display gray level, which has been measured in advance. The
`
`brightness variation is shown as curve 22. Therefore, the time for obtaining the
`
`expected brightness can be reduced from t0 to to'; this is the so-called OD technique.
`
`Referring to Fig.3A to 3C,
`
`if the expected brightness of an image in the
`
`preceding frame interval H is code 32, and the expected brightness of the said image
`
`in the present frame interval I becomes code 120, the brightness variation of the liquid
`
`crystal display is shown as curve (a) without making use of OD technique. It is shown
`that the expected brightness cannot be obtained unless the I+1th frame interval is got.
`This would produce the problem of residue image: By use of OD technique, the
`driving voltage is increased to code 200 in the present frame interval I to be able to
`
`obtain the expected brightness at the end of the frame interval. Its brightness variation
`
`is shown as curve (b). In the driving process of the first gate line G] and the first data
`
`line D1, when the frame interval I begins, a control voltage pulse is given to the first
`
`gate line G1 by the gate driver and at the same time a driving voltage code 200 is
`
`given to the first data line D1 by the data driver so that the first pixel (not shown)
`
`connected with the first gate line and the first data line can change its brightness. If
`
`the sequential frame interval still display the brightness of code 120 and the next
`
`frame interval I+1 begins, a control voltage pulse is still given to the first gate line and
`
`the driving voltage given to the first data line is decreased to code 120 to keep the
`
`expected brightness.The present invention makes use of the “overdrive” concept and

`
`SUMMARY OF THE INVENTION
`
`The chief object of the present invention is to provide a liquid crystal display
`
`driving device of matrix structure type to increase the response speed of the liquid
`
`crystal display and the aspect ratio of the panel and to decrease the number of the data
`drivers and the data lines.

`
`Another object of the present invention is to provide a driving method for the
`
`liquid crystal display of matrix structure type, which can simultaneously or
`
`synchronously start the plurality of thin film transistors in the display panel and drive
`
`the pixels controlled by the thin film transistors to reduce the response time of the
`liquid crystal display.
`
`To achieve the above-stated objects of the present invention, the basic structure
`
`of the driving device of the present invention includes a group of thin film transistors
`
`with matrix array, gate lines connected with the gate drivers and insulated with each
`
`other, wherein the gates and the sources of all the thin film transistors are respectively
`
`connected with the gate lines and the data lines. The response time of the liquid
`
`crystal display can be reduced by the difierent arrangement design of the gate lines
`
`and the data lines and by the different connection location between the gate lines and
`the gates of the thin film transistors and between the data liens and the sources of the
`
`thin film transistors. The gate drivers can be respectively installed on the left side and
`
`the right side of the liquid crystal panel and the data drivers can be respectively
`
`installed on the upper side and the lower side. The gate driver can be a chip installed
`
`on glass or an integrated gate driver circuit installed on glass.
`
`The driving method for the said driving device includes:
`
`the period of the
`
`predetermined voltage of the over drive received by the thin film transistors connected
`
`with the first gate line is set as a over exciting period and the period of the data
`
`voltage of the present frame interval received by the thin film transistor connected
`
`with the first gate line is set as a brightness keeping period.
`
`When the over exciting period begins, two gate lines in the liquid crystal display
`
`are turned on in a time of one synchronous control signal or by the control signals
`simultaneously produced by the gate drivers. The predetermined voltage is given to
`
`SAMSUNG EX. 1002 - 6/188
`
`SAMSUNG EX. 1002 - 6/188
`
`

`

`the thin film transistors connected with one of the gate lines which are simultaneously
`or synchronously turned on,
`the data voltage is given to the thin film transistors
`
`connected with the other of the gate lines which are simultaneously or synchronously
`turned on, and scanning continues in turn.
`
`When the brightness keeping period begins, two gate lines in the liquid crystal
`display are orderly turned on in a time of one synchronous control signal or by the
`control signals simultaneously produced by the gate drivers. One of the gate lines is
`the next gate line of the last gate line given to the said predetermined voltage. The
`predetermined voltage of over drive is given to the thin film transistors connected
`
`with the said gate line, and the data voltage of the present frame interval is given to
`the thin film transistors connected with the first gate line which is turned on orderly.
`Scanning continues in turn until the whole liquid crystal display is scanned, and the
`next frame interval begins.
`
`If the ratio of the number of the gate lines scanned in the over excited period to
`the number of the total gate lines is P and the period of the frame interval of the liquid
`crystal display is T, then the duration of the over exciting is PT and the duration of the
`brightness keeping is
`(1 -P)T. The ratio P can be adjusted according to the
`characteristic of the display panel.
`
`the
`invention possesses
`the present
`stated above,
`statement
`From the
`characteristic of dividing the space of the gate lines of the display panel into a
`plurality of regions and the time of the frame interval into a plurality of sub-region .
`times. Each region is orderly scanned in a time of one synchronous control signal.
`Therefore, the state of “frame in frame” is formed in the space and the time. The
`method of the present invention can suit for various picture treatments of liquid
`crystal display, organic light emitting diode (OLED) display or plasma display panel
`(PDP).
`
`To make the present invention be able to be clearly understood, there are some
`preferred embodiments and their accompanying draws described in detail as below.

`
`DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
`
`Referring to Fig.2, because each liquid crystal display panel has its characteristic
`
`and each of brightness of the liquid crystal display panel is produced by a preset
`
`driving voltage,
`
`it is necessary for the OD driving technique that the brightness
`
`variation of the panel at various driving voltages would be measured in advance. On
`
`the curve in the Fig.2, the brightness, which is marked 21, 22, 23, 24, and 25,
`
`is
`
`respectively produced by the voltage V,, V2, V3, V4, and V5. If need be, the number
`
`of the curves about the measured brightness can be increased. The variation data of
`
`the curve can be made into a lookup table, which can be stored in the electronic
`
`elements of the liquid crystal display and become the base on which the driver can
`
`select the voltage to produce the brightness of the panel. The means about this
`
`technique can be arbitrarily modified and varied by the persons skilled at this art.
`
`The first embodiment
`
`Referring to Fig.4A to 4C, they show a preferred embodiment of the liquid
`
`crystal display driving device of matrix structure type according to the present
`
`invention. The driving device includes a group of thin film transistors Q with matrix
`
`array, which consists of N rows and M columns of thin film transistors, wherein, each
`
`thin film transistor Q can drive one pixel, so N x M pixels (shown by rectangle with
`
`dotted line) can be driven. The first gate line G, is connected with the gates of all the
`
`thin film transistors Q of the first row, the second gate line G2 is connected with the
`
`gates of all the thin film transistors Q of the second row, and so are the others.
`
`Therefore, there are N gate lines connected to gate driver and they are insulated with
`each other.
`
`The first and the second data lines D1, D1. of the first group of data lines are
`
`respectively connected with the sources of all the thin film transistors Q of the odd
`
`and the even rows of the first column. The first and the second data lines D2 , D2. of the
`
`second group of data lines are respectively connected with the sources of all the thin
`
`film transistors Q of the odd and the even rows of the second column and so are the
`
`others. Therefore,
`
`in total there are M groups of data lines connected to the data
`
`drivers and they are insulated with each other. To prevent the neighboring data lines
`
`from short circuit, for example, the second data line D,. of the first group of data lines
`
`and the first data line D2 of the second group of data lines, a space is given between
`
`the neighboring data lines, of which arrangement is shown as Fig. 4C.

`

`As shown in Fig. 4A, the data drivers connected with the data lines are installed
`
`on the same side of the display panel. If the scanning frequency is 60 Hz and there are
`
`two gate lines being turned on at the same time, the scanning time can be further
`
`decreased. Referring to Fig. 5A and 5B, the data drivers are respectively arranged on
`
`the upper and the lower sides of the liquid crystal display, and the first and the second
`
`data line of each group of data lines are respectively connected with the data drivers
`
`of the upper and the lower sides of the liquid crystal display, wherein, the scanning
`
`frequency of the data drivers is kept at 60 Hz. Referring to Fig. 6A and 6B, the first
`
`data line of each group of data lines and the neighboring second line of another group
`
`of data lines are connected with the same data drivers, and the data transfer is
`
`switched by an electronic switch S of which scanning frequency
