`(110)
`which comprises a plurality of
`scanning lines
`(SLia,SLib)arranged in rows and a plurality of
`data lines (DLja
`DLjd) arranged in columns ;
`and a plurality of display pixels (EM) arranged
`in matrix form near the intersecting point of the
`plurality of scanning lines and the plurality of data
`lines; a scanning driver circuit (120) which selects
`simultaneously the display pixels of a plurality of
`rows connected to some of the plurality of scanning
`lines of the display panel; and a signal driver circuit
`(130) which comprises a current generation circuit
`(CG) which generates signal currents and supplies
`the display data that provides the display gradation
`for each of the display pixels and have a current
`value according to the value of the display data and
`a plurality of current holding circuits (CH) supplied
`with the signal currents which take in and hold the
`signal currents corresponding to the display pixels
`of the plurality of rows selected by the scanning
`driver circuit (120) and outputs simultaneously the
`gradation currents to each of the plurality of display
`pixels in the plurality of scanning lines based on
`the signal currents. The display panel comprising
`a plurality of scanning line groups (SLi) which
`constitute sets of the plurality of scanning lines
`N through which simultaneous selection is performed by the scanning driver circuit; a plurality of scanning signal lines (SSLi) which
`are connected to each of the plurality of scanning line groups; and a plurality of data line groups (DLj) which constitute sets of the
`plurality of data lines corresponding to the line count of the display pixels of the plurality of rows connected to each of the scanning
`line groups Within the plurality of data lines.

`
`lM
` Box ll Cheervations where certain claims were found unsearchabie (Continuation of item 2 of first sheet)
`
`This international Search Report has not been established in respect of certain claims under Article 17(2)(a) for the following reasons;
` t. D Claims Nos.:
`
`because they relate to subject matter not required to be searched by this Authority, namely:
`
`3. I: Claims Nos.:
`because they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a)i
`
`Box Ill Observations where unity of invention is lacking (Continuation of item 3 of first sheet)
`
`This international Searching Authority found multiple inventions in this international application, as follows:
`
`_
`2. El Claims Nos.:
`
`
`because they relate to parts of the lntemational Application that do not comply with the prescribed requirements to such
`
`an extent that no meaningful International Search can be carried out, specifically:
`
`
`
`
`
`
` see addi ti onai sheet
`
`
`As all required additional search fees were timel
`
`searchable claims.
`
`
`y paid by the applicant, this international Search Report covers all
`
`
`
`of any additional fee.
`
`
`As all searchable claims could be searched without effortjustifying an additional fee, this Authority did not invite payment
`
`
`
` As only some of the required additional search fees were timely paid by the applicant, this international Search Report
`
`
`covers only those claims for which fees were paid, specifically claims Nos.:
`
`
` No required additional search fees were timely paid by the applicant. Consequently, this international Search Report is
`
`restricted to the invention first mentioned in the claims; it is covered by claims Nos.:
`
`
` Remark on Protest
`D The additional search fees were accompanied by the applicant's protest.
`
`
`D No protest accompanied the payment of additional search fees.

`
`
`This International Searching Authority found multiple (groups of)
`inventions in this international application, as follows:
`
`
` 1. claims: 1-12
`
`
`The first concept concerns a driver circuit for driving a
`plurality of display pixels with a pixel selection circuit
`suitable for setting simultaneously a plurality of pixels to
`
`
`the selection state, a current generation circuit for
`generating signal currents having a current value according
`
`
`to gradiation signals, and a plurality of current holding
`
`
`circuits for sequentially storing the signal currents from
`the current generation circuit, and outputting
`
`
`simultaneously the signal currents to the plurality of
`display pixels, wherein
`'
`
`
`the current holding circuits comprise a pair of current
`
`
`storage sections arranged in parallel, wherein
`{the current storage sections comprise a voltage component
`
`
`holding sections having a capacitative element
`in which the
`electric charge output from the current generation circuit
`
`
`is written and hold as the voltage component corresponding
`to the current value of the signal currents, and
`field-effect-transistors which flow the signal currents
`
`
`between the source—drain;
`the capacitative element at least
`consists of parasitic capacitance between the source-gate of
`
`
`the field effect transistors; and the voltage between the
`source—gate based on the signal currents is written in the
`
`capacitative element.
`
`
`
`2. claims: 13-41
`
`
`
`The second concept concerns a display device with a
`plurality of display pixels at the intersections of a
`plurality of scanning lines and a plurality of data lines,
`
`with a scanning driver circuit for selecting scanning lines,
`
`and a signal driver circuit with a current generation
`circuit for generating signal currents having a current
`
`value according to gradiation signals, and a plurality of
`
`current holding circuits for sequentially storing the signal
`
`currents from the current generation circuit, and outputting
`
`simultaneously the signal currents to the plurality of
`display pixels, wherein
`
`a plurality of scanning lines are connected together and are
`simultaneously selelected by the scanning driver circuit.
