Description

  The present invention relates to an electro-optical device and an electronic apparatus.

  An electro-optical device using an electro-optical material such as a liquid crystal has been widely used. As one of methods for driving such an electro-optical device, a multiplexer method is known (see, for example, Patent Document 1). FIG. 15 is a diagram illustrating a schematic configuration of the electro-optical device 10 according to Patent Document 1. As illustrated in FIG. The electro-optical device 10 shown in FIG. 15 includes a plurality (3N) of data lines 104 divided into a plurality of (N) blocks B every three, and a data line driving circuit 30 that drives each data line 104. A plurality of pixel circuits 11 corresponding to the respective data lines 104 and a plurality of image signal lines 106 corresponding to the respective blocks B are provided. In FIG. 15, among the three data lines 104 included in each block B, the display color of each pixel circuit element 11 corresponding to the data line 104 in the first column counting from the left is “R (red)”. The display color of each pixel circuit 11 corresponding to the data line 104 in the second column is “G (green)”, and the display color of each pixel circuit 11 corresponding to the data line 104 in the third column is “B”. (Blue) ".

  The data line driving circuit 30 illustrated in FIG. 15 includes N selection units 50 corresponding to the respective blocks B. Each of the three switches 51 in the selection unit 50 (demultiplexer) of the i-th stage (1 ≦ i ≦ N) is interposed between the image signal line 106 and the data line 104 of the i-th stage. Control the electrical connection. The first stage switch 51 of each block B is controlled by the sampling signal SEL-R, the second stage switch 51 is controlled by the sampling signal SEL-G, and the third stage switch 51 is controlled by the sampling signal SEL-. B is controlled.

  As shown in FIG. 16, the three sampling signals (SEL-R, SEL-G, and SEL-B) are sequentially shifted to the active level in the periods T1 to T3 in the horizontal scanning period H in which the scanning line is selected. To do. Accordingly, the three switches 51 in each selection unit 50 are turned on in turn. As shown in FIG. 16, the gradation signal d supplied to each image signal line 106 is set to the potential VR in the period T1, set to the potential VG in the period T2, and set to the potential VB in the period T3. Is done. Accordingly, in the period T1, the potential VR is supplied to the data line 104 in the first column of each block B, in the period T2, the potential VG is supplied to the data line 104 in the second column, and in the period T3, the potential in the third column is supplied. A potential VB is supplied to the data line 104. On the other hand, when the switch 51 transits to the off state, the data line 104 enters an electrically floating state.

  By the way, a parasitic capacitance accompanies between adjacent data lines 104. In FIG. 15, the data line 104 in the first column of the (k + 1) th block Bk + 1 (1 ≦ k ≦ N−1) is capacitively coupled to the data line 104 in the second column of the block Bk + 1, and the block Capacitively coupled to the data line 104 in the third column of the kth block Bk adjacent to the negative side in the X direction when viewed from Bk + 1. The data line 104 in the second column of the block Bk + 1 is capacitively coupled to the data line 104 in the first column and the data line 104 in the third column of the block Bk + 1.

  Now, the case where the potential VR is supplied to the data line 104 in the first column in the period T1, and then the potential VG is supplied to the data line 104 in the second column in the period T2 after the lapse of the period T1. Think. In the period T2, the data line 104 in the first column is in an electrically floating state. Accordingly, as shown in FIG. 16, at the time t1 when the potential of the data line 104 in the second column changes from the immediately preceding potential to the potential VG, the first data line capacitively coupled to the data line 104 in the second column. The potential of the data line 104 in the column changes from the desired potential VR by a potential ΔV1 corresponding to the amount of change in the potential of the data line 104 in the second column.

  Next, consider a case where the potential VB is supplied to the data line 104 in the third column in the period T3 after the lapse of the period T2. In the period T3, the data line 104 in the second column and the data line 104 in the first column are in an electrically floating state. Accordingly, as shown in FIG. 16, at the time t2 when the potential of the data line 104 in the third column changes from the previous potential to the potential VB, the second data line capacitively coupled to the data line 104 in the third column. The potential of the data line 104 in the column changes from the desired potential VG by a potential ΔV2 corresponding to the amount of change in the potential of the data line 104 in the third column. Further, the potential of the first column data line 104 of the block Bk + 1 that is capacitively coupled to the third column data line 104 of the block Bk also corresponds to the amount of change in the potential of the third column data line 104. It changes from the previous potential by the potential ΔV3.

As described above, in each block B, the potential of the data line 104 in the first column set to the potential VR in the period T1 is t1 when the potential VG is supplied to the data line 104 in the second column in the period T2. And the time t2 when the potential VB is supplied to the data line 104 in the third column in the period T3. On the other hand, the potential of the second column data line 104 set to the potential VG in the period T2 varies because the potential VB is supplied to the third column data line 104 in the period T3 after the period T2. Only at time t2. As a result, as shown in FIG. 17, the luminance characteristic of “R (red)” that is the display color of the pixel circuit 11 corresponding to the data line 104 in the first column (relationship between the designated gradation and the actual luminance). And the luminance characteristic of “G (green)”, which is the display color of the pixel circuit 11 corresponding to the data line 104 in the second column, and the display color of the pixel circuit 11 corresponding to the data line 104 in the third column. There is a problem that variation occurs between the luminance characteristics of a certain “B (blue)”.
In view of the above circumstances, an object of the present invention is to solve the problem of suppressing the gradation of each electro-optic element from varying for each data line due to the parasitic capacitance between the data lines.

  In order to solve the above-described problems, an electro-optical device according to the present invention includes a plurality of data lines divided into a plurality of blocks in units of three or more, and a plurality of electric lines arranged corresponding to each data line. An optical element, a plurality of image signal lines corresponding to each of the plurality of blocks, and a plurality of blocks are arranged corresponding to each of the plurality of blocks, and each data line belonging to the block is selected in a time-sharing manner to the block. And a plurality of selection means for executing the operation of conducting the corresponding image signal line in parallel for a plurality of blocks. The plurality of data lines are the first data lines (for example, the data line 104 of the block Bk + 1 shown in FIG. 3). [1]) and a second data line (for example, the block shown in FIG. 3) that is located on one side of the first data line (eg, the negative side in the X direction shown in FIG. 3) and is selected after the selection of the first data line B Data line 104 [2]) and a third data line (for example, selected after the selection of the second data line, which is arranged between the first data line and the second data line and is adjacent to both data lines) Data adjacent to the data line 104 [3] of the block Bk shown in FIG. 3 and the other side of the first data line (for example, the positive side in the X direction shown in FIG. 3) and selected after the selection of the first data line Line (for example, data line 104 [2] of block Bk + 1 shown in FIG. 3) and a data line (for example, the block shown in FIG. 3) that is adjacent to one side of the second data line and selected before the second data line is selected. Bk data line 104 [1]), and the distance between the first data line and the third data line (for example, in FIG. 3) in a capacitance adjustment area different from the display area in which each electro-optic element is arranged. L3) indicates that the second data line and the third data line Spacing greater than (L2 shown in FIG. 3 for example).

  According to this aspect, by setting the interval between the first data line and the third data line to be larger than the interval between the second data line and the third data line, the interval between the first data line and the third data line is established. The value of the parasitic capacitance associated with is reduced, and the value of the parasitic capacitance associated with the second data line and the third data line is increased. Therefore, the amount of change in potential of the first data line caused by the selection of the third data line is suppressed, and the amount of change in potential of the second data line caused by the selection of the third data line is increased. The difference between the total potential change amount of the first data line in which the data potential changes twice and the potential change amount in the second data line in which the data potential changes only once can be reduced. As a result, it is possible to suppress variations in the luminance characteristics of the electro-optical element corresponding to the first data line and the luminance characteristics of the electro-optical element corresponding to the second data line, thereby suppressing deterioration in display quality of the electro-optical device. There is an advantage that you can.

  The electro-optical device according to the present invention includes a plurality of data lines that are divided into a plurality of blocks in units of three or more, a plurality of electro-optical elements that are arranged corresponding to the data lines, and a plurality of blocks. A plurality of image signal lines corresponding to each of the plurality of blocks and a plurality of blocks arranged in correspondence with each of the plurality of blocks and each data line belonging to the block are selected in a time-sharing manner to be conducted to the image signal lines corresponding to the block. A plurality of selection means for performing an operation in parallel on a plurality of blocks, and the plurality of data lines are selected before the selection of two data lines adjacent to both sides (for example, FIG. 3). Data line 104 [1]) of block Bk + 1 shown in FIG. 3 and a second data line (for example, shown in FIG. 3) selected after selection of the data line adjacent to one side and before selection of the data line adjacent to the other side. Show bro And Bk + 1 data lines 104 [2]) in a capacitance adjustment region different from the display region in which each electro-optic element is arranged, and two data lines adjacent to both sides of the first data line. The interval (eg, L1 + L3 shown in FIG. 3) is larger than the interval between two data lines adjacent to both sides of the second data line (eg, L1 + L2 shown in FIG. 3), and the interval between the second data line and the second data line is larger. The distance (eg, L1 shown in FIG. 3) between the data line adjacent on one side (eg, the data line 104 [1] of the block Bk + 1 shown in FIG. 3) is the other side of the second data line and the second data line. Is larger than the interval (for example, L2 shown in FIG. 3) between the adjacent data lines (for example, the data line 104 [3] of the block Bk + 1 shown in FIG. 3).

  According to this aspect, the value of the parasitic capacitance between the first data line and each of the two data lines adjacent to both sides of the first data line is the second data line and the second data. The first data line generated by selection of two data lines adjacent to both sides of the first data line because the value of the parasitic capacitance associated with each of the two data lines adjacent to both sides of the line is smaller The amount of potential change can be suppressed. Further, the value of the parasitic capacitance that accompanies the second data line and the data line adjacent to the second data line on the other side is adjacent to the second data line on one side of the second data line. Since it is larger than the value of the parasitic capacitance associated with the data line, the potential change amount of the second data line caused by the selection of the data line adjacent to the other side of the second data line can be increased. Therefore, the difference between the total amount of potential change of the first data line in which the data potential changes twice and the potential change amount of the second data line in which the data potential changes only once can be reduced. It can be suppressed that the luminance characteristic of the corresponding electro-optical element and the luminance characteristic of the electro-optical element corresponding to the second data line vary.

  In the electro-optical device according to the aspect of the invention, it is preferable that the display color of the electro-optical element corresponding to the first data line is the same as the display color of the electro-optical element corresponding to the second data line. The variation in luminance characteristics between pixels with the same display color is more visible to the observer than the variation in luminance characteristics between pixels with different display colors. The variation in luminance characteristics can be made smaller than the variation in luminance characteristics between pixels with different display colors. Accordingly, there is an advantage that it is possible to suppress a decrease in display quality of the electro-optical device.

  Further, as an aspect of the electro-optical device according to the present invention, the color displayed on each of the electro-optical element corresponding to the first data line and the electro-optical element corresponding to the second data line is displayed by each electro-optical element. Of the plurality of colors, a color other than the color having the lowest visibility is preferable. For the color with the lowest visibility, even if the luminance characteristics vary with other colors, the variation is difficult to be perceived by the observer, so the variation in the luminance characteristics for the colors other than the color with the lowest visibility is suppressed. It is preferable to do.

  Further, as an aspect of the electro-optical device according to the present invention, a precharge potential can be supplied to each of the plurality of data lines before the selection of the first data line in each block is started. In this embodiment, since the precharge potential is supplied to each data line regardless of the gray level of the electro-optic element before the data line is selected (before the data potential is supplied), the potential change (pre-voltage) of each data line is supplied. The frequency and amount of change (charge potential → data potential) are larger than in the case where precharge is not performed before selection of the data line. In such a case, the configuration of the present invention is particularly effective.

  In addition, the electro-optical device according to the invention is used in various electronic apparatuses. A typical example of this electronic apparatus is an apparatus using an electro-optical device as a display device. Examples of this type of device include personal computers and mobile phones. However, the use of the electro-optical device according to the present invention is not limited to image display. For example, in an image forming apparatus (printing apparatus) configured to form a latent image on an image carrier such as a photosensitive drum by irradiation of light, the electro-optic of the present invention is used as a means for exposing the image carrier (so-called exposure head). An apparatus can also be employed.

<A: First Embodiment>
FIG. 1 is a block diagram showing a configuration of an electro-optical device 10 according to the first embodiment of the present invention. The electro-optical device 10 is a device that is employed in various electronic devices as means for displaying an image. The electro-optical device 10 includes a pixel array unit 100 in which a plurality of pixel circuits 11 are arranged in a plane, and a scanning line driving circuit 20. And a data line driving circuit 30 and a control circuit 40.

  As shown in FIG. 1, the pixel array unit 100 is provided with m scanning lines 102 extending in the X direction and 3n data lines 104 extending in the Y direction orthogonal to the X direction ( m and n are natural numbers). Each pixel circuit 11 is arranged at a position corresponding to the intersection of the scanning line 102 and the data line 104. Accordingly, these pixel circuits P are arranged in a matrix of m rows × 3n columns. Each pixel circuit 11 includes a liquid crystal element composed of a pixel electrode opposed to each other with a space therebetween, and a counter electrode and a liquid crystal therebetween. The transmittance of each liquid crystal element (the ratio of the amount of light transmitted to the observation side from the light emitted from the backlight (not shown) to the liquid crystal element) varies depending on the voltage applied to the liquid crystal element. In the present embodiment, a normally black mode in which the transmittance of the liquid crystal element increases as the voltage applied to the liquid crystal element increases.

  The scanning line driving circuit 20 is a circuit for selecting a plurality of pixel circuits 11 in units of rows every horizontal scanning period (1H). The scanning line driving circuit 20 outputs the scanning signals G1 to Gm that are sequentially activated to each of the m scanning lines 102. The transition to the active level of the scanning signal Gi output to the scanning line 102 in the i-th row (1 ≦ i ≦ m) means selection of the i-th row.

  In the present embodiment, the 3n data lines 104 include n blocks B (B1, B2,...) In units of three adjacent ones (104 [1], 104 [2], 104 [3]).・ Bn). As shown in FIG. 1, among the three data lines 104 included in each block B, the display color of each pixel circuit 11 corresponding to the data line 104 [1] in the first column counted from the left is “R ( Red) ”. Further, the display color of each pixel circuit 11 corresponding to the data line 104 [2] in the second column from the left is “G (green)”. Further, the display color of each pixel circuit 11 corresponding to the data line 104 [3] in the third column from the left is “B (blue)”.

  A control circuit 40 shown in FIG. 1 is a circuit for controlling the overall operation of the electro-optical device 10. The control circuit 40 outputs a control signal such as a clock signal to the scanning line driving circuit 20 and the data line driving circuit 30, and also generates sampling signals S1 to S3 and outputs them to the sampling signal lines 41a to 41c. .

  The data line driving circuit 30 includes n selection units 50 corresponding to each block B, a signal output circuit 32, and n image signal lines 106 corresponding to each block B. As shown in FIG. 1, each selection unit 50 includes three switching elements 51 each disposed between an image signal line 106 and a data line 104. The gate of each switching element 51 is connected to the sampling signal line 41. More specifically, the gate of each switching element 51 corresponding to the data line 104 [1] of each block B is connected in parallel to the sampling signal line 41a, and each switching element 51 corresponding to the data line 104 [2]. Are connected in parallel to the sampling signal line 41b, and the gate of each switching element 51 corresponding to the data line 104 [3] is connected in parallel to the sampling signal line 41c.

  When the sampling signal Sf (f = 1 to 3) transitions to the active level, the n switching elements 51 corresponding to the data lines 104 [f] of each block B are turned on simultaneously, and the data lines of each block B are turned on. 104 [f] is electrically connected to the image signal line 106 corresponding to the block B. For example, when the sampling signal S1 transitions to the active level, n switch elements 51 corresponding to the data lines 104 [1] of each block B are turned on at the same time, and the data lines 104 [1] of each block B That is, the image signal line 106 corresponding to the block B becomes conductive. In the present embodiment, the transition of the sampling signal Sf to the active level means selection of the data line 104 [f] in the f-th column in each block B.

  The signal output circuit 32 generates n systems of gradation signals d corresponding to each block B and outputs them to the image signal lines 106. The gradation signal d supplied to each image signal line 106 includes three pixels corresponding to the intersections of the data lines 104 for three columns of the block B corresponding to the image signal line 106 and the selected scanning line 102. This is a voltage signal for designating the gradation of the circuit 11 in a time division manner.

  FIG. 2 is a timing chart showing the operation of the electro-optical device 10. As shown in FIG. 2, the scanning signal Gi output from the scanning line driving circuit 20 sequentially becomes a high level (active level) every horizontal scanning period (1H). That is, the scanning signal Gi maintains a high level in the i-th horizontal scanning period in the vertical scanning period and maintains a low level (inactive level) in other periods.

  As shown in FIG. 2, one horizontal scanning period H includes a precharge period Tp from when the horizontal scanning period H starts until a predetermined period elapses, and a first period T1 after the precharge period Tp elapses. The second period T2 after the elapse of the first period T1 and the third period T3 after the elapse of the second period T2. In FIG. 2, only the first horizontal scanning period H in which the scanning line 102 in the first row is selected is illustrated, but the same applies to the other horizontal scanning periods H.

  The precharge period Tp is a period in which a common precharge potential Vp is simultaneously supplied (precharged) to the 3n data lines 104. As shown in FIG. 2, in the precharge period Tp, the sampling signals S1 to S3 are simultaneously changed to a high level (active level). Thereby, the three switching elements 51 belonging to each block B are turned on simultaneously. In the precharge period Tp, the gradation signal d output from the data line driving circuit 30 to each image signal line 106 is set to the precharge potential Vp, and the precharge potential Vp is simultaneously applied to all the data lines 104. Supplied. In the present embodiment, the precharge potential Vp is set to a potential for displaying an intermediate gradation (gray) when supplied to each pixel circuit 11. When the precharge period Tp ends, the sampling signals S1 to S3 are simultaneously shifted to the low level, and the three switching elements 51 belonging to each block B are simultaneously turned off.

  As shown in FIG. 2, in the first period T1 to the third period T3, the three systems of sampling signals S (S1 to S3) sequentially shift to the active level. As shown in FIG. 2, in the first period T1, the sampling signal S1 transitions to a high level, while the sampling signals S2 and S3 maintain a low level. Accordingly, the switching element 51 corresponding to the data line 104 [1] of each block B is turned on, and the data line [1] of each block B and the image signal line 106 corresponding to the block B become conductive. . In the first period T1, the gradation signal d supplied from the signal output circuit 32 to each image signal line 106 includes the data line 104 [1] in the block B corresponding to the image signal line 106 and the selected scanning line. The potential VR corresponding to the gray level of the pixel circuit 11 corresponding to the intersection with the pixel 102 is set, and the potential VR is supplied to the data line 104 [1].

  Similarly, in the second period T2, the switching element 51 of the second stage of each selection unit 50 is turned on by the high level sampling signal S2, so that the data line 104 [2] of each block B is turned on. A gradation signal d of potential VG is supplied. In the third period T3, the third-stage switching element 51 of each selection unit 50 is turned on by the high-level sampling signal S3, so that the potential on the data line 104 [3] of each block B A VB gradation signal d is supplied.

  On the other hand, as shown in FIG. 2, since the sampling signal Sf maintains a low level in a period other than the precharge period Tp and the period Tf, the data line 104 [f] is in an electrically floating state in this period.

  By the way, a parasitic capacitance accompanies between adjacent data lines 104. For example, in FIG. 1, the data line 104 [1] of the (k + 1) th block Bk + 1 (1 ≦ k ≦ n−1) is capacitively coupled to the data line 104 [2] of the block Bk + 1 and is viewed from the block Bk + 1. And capacitively coupled to the data line 104 [3] of the kth block Bk adjacent to the negative side in the X direction. The data line 104 [2] of the block Bk + 1 is capacitively coupled to the data line 104 [1] and the data line 104 [3] of the block Bk + 1.

  Now, the potential VR supplied to the data line 104 [1] in the first period T1 is set to the potential Vg (= Vp) corresponding to the intermediate gradation, and is supplied to the data line 104 [2] in the second period T2. A case is considered in which the potential VG is set to the potential Vm corresponding to black (<Vp), and the potential VB supplied to the data line 104 [3] in the third period T3 is set to the potential Vm corresponding to black.

  As shown in FIG. 2, at the start point t1 of the second period T2, the potential of the data line 104 [2] changes from the precharge potential Vp to the potential Vm. Since the data line 104 [1] is in an electrically floating state in the second period T2, as shown in FIG. 2, when the potential of the data line 104 [2] changes at the time t1, the data line 104 [2] The potential of the data line 104 [1] that is capacitively coupled to the potential changes from the potential Vg set in the first period T1 by the potential ΔV1 corresponding to the amount of change in the potential of the data line 104 [2] (Vp → Vm). To do.

  Similarly, at the start point t2 of the third period T3, the potential of the data line 104 [3] of each block B changes from the precharge potential Vp to the potential Vm. In the third period T3, since the data line 104 [1] and the data line 104 [3] are in an electrically floating state, as shown in FIG. 2, when the potential of the data line 104 [3] changes at time t2. The potential of the data line 104 [2] capacitively coupled to the data line 104 [3] changes from the potential Vm set in the second period T2 to the potential change amount (Vp → Vm) of the data line 104 [3]. It changes by the corresponding potential ΔV2. Further, when the potential of the data line 104 [3] of the block Bk changes at time t2, the potential of the data line 104 [1] of the block Bk + 1 that is capacitively coupled to the data line 104 [3] is also in the second period T2. The potential Vg−ΔV1 changes by a potential ΔV3 corresponding to the amount of change in the potential of the data line 104 [3].

  That is, in each block B, the potential of the data line 104 [1] set to the potential Vg in the first period T1 is equal to the third time t1 when the potential Vm is supplied to the data line 104 [2] in the second period T2. It fluctuates twice in total with the supply time t2 of the potential Vm to the data line 104 [3] in the period T3. On the other hand, the potential of the data line 104 [2] set to the potential Vm in the second period T2 varies only once at the time t2 when the potential Vm is supplied to the data line 104 [3] in the third period T3. Accordingly, the luminance characteristic of “R” that is the display color of the pixel circuit 11 corresponding to the data line 104 [1] and the luminance characteristic of “G” that is the display color of the pixel circuit 11 corresponding to the data line 104 [2]. There arises a problem that variation occurs between the characteristic and the luminance characteristic of “B” which is the display color of the pixel circuit 11 corresponding to the data line 104 [3].

  In order to suppress the variation in the luminance characteristics of the respective display colors (“R”, “G”, “B”) as described above, in the present embodiment, the area A shown in FIG. The capacitance between the data lines 104 is adjusted by adjusting the interval between the data lines 104. As shown in FIG. 1, the capacitance adjustment area A is an area between the pixel array unit 100 and the data line driving circuit 30. FIG. 3 is a schematic diagram showing the arrangement of the data lines 104 in the capacity adjustment area A. As shown in FIG. FIG. 3 shows a kth (1 ≦ k ≦ n−1) block Bk counted from the left and a (k + 1) th block Bk + 1.

  As shown in FIG. 3, in each block B, the data line 104 [1] and the data line 104 [2] are adjacent to each other with an interval L1, and the data line 104 [2] and the data line 104 [3] are Adjacent with an interval L2. Further, as shown in FIG. 3, the interval L3 between the data line 104 [1] in the block Bk + 1 and the data line 104 [3] in the block Bk is equal to the data line 104 [2] and the data line 104 [3 in the block Bk. ] Is larger than the interval L2. A relationship of L2 + L3 = 2L1 is established between the intervals L1, L2, and L3. That is, as shown in FIG. 4, the position of the data line 104 [3] in each block B in the form in which the data lines 104 are arranged at equal intervals L1 (hereinafter referred to as “proportional”) is defined as a predetermined distance ΔL ( 3 is shifted to the negative side in the X direction by L1-ΔL = L2, L1 + ΔL = L3). These relationships are the same in the other blocks B.

  From another viewpoint, in FIG. 3, two data lines adjacent to both sides of the data line 104 [1] of the block Bk + 1 (the data line 104 [2] of the block Bk + 1 and the data line 104 [3] of the block Bk) ) Interval L1 + L3 is larger than the interval L1 + L2 between two data lines 104 adjacent to both sides of the data line 104 [2] of the block Bk + 1 (the data line [1] 104 and the data line 104 [3] in the block Bk + 1). The interval L1 between the data line 104 [2] and the data line 104 [1] selected before the selection of the data line 104 [2] is selected between the data line 104 [2] and the data line 104 [2]. It is larger than the interval L2 with the data line 104 [3] selected later. In the present embodiment, the data lines 104 positioned in the pixel array unit 100 are arranged at equal intervals L1.

  As described above, in this embodiment, the distance L3 between the data line 104 [1] and the data line 104 [3] adjacent to the negative side in the X direction when viewed from the data line 104 [1] is proportional. Since the value is larger than the other, the value of the parasitic capacitance Cx between the two is smaller than the proportionality. Accordingly, the amount of change ΔV3 in the potential of the data line 104 [1] linked to the change in potential of the data line 104 [3] (Vp → Vm) at the time point t2 in the third period T3 is smaller than the proportionality.

  In this embodiment, since the distance L2 between the data line 104 [2] and the data line 104 [3] is smaller than the proportionality, the distance between the data line 104 [2] and the data line 104 [3] The value of the parasitic capacitance Cy associated with is larger than the proportionality. Therefore, the change amount ΔV2 of the potential of the data line 104 [2] linked to the change of the potential of the data line 104 [3] (Vp → Vm) at the time point t2 in the third period T3 is larger than the proportionality.

  That is, according to the present embodiment, the total potential change amount (= ΔV1 + ΔV3) of the data line 104 [1] at time t1 and time t2 and the potential change amount of the data line 104 [2] at time t2. The difference from (= ΔV2) can be made smaller than the proportionality. Accordingly, as shown in FIG. 5, the luminance characteristic of “R”, which is the display color of the pixel circuit 11 corresponding to the data line 104 [1], and the display color of the pixel circuit 11 corresponding to the data line 104 [2]. The variation with the brightness characteristic of a certain “G” can be suppressed as compared with the comparative aspect shown in FIG. In other words, there is an advantage that deterioration in display quality of the electro-optical device 10 can be suppressed.

  According to the present embodiment, it is possible to suppress variation between the luminance characteristics of “R” and “G” among the display colors “R”, “G”, and “B” that are display colors of the pixel circuits 11. The luminance characteristic of “B” and the luminance characteristic of “R” or “G” vary. However, since “B” has a lower relative visibility than “R” and “G”, even if the luminance characteristics vary with other colors, the variation is hardly perceived by the observer. For this reason, as in this embodiment, it is preferable to suppress variations in luminance characteristics for colors other than “B” having the lowest visibility.

  If, for example, an electrostatic protection circuit or an inspection circuit is provided in the capacity adjustment region A, the interval between the data lines 104 may be reduced. In this case, since the value of the parasitic capacitance between the data lines 104 located in the capacitance adjustment region A also increases, variation in luminance characteristics between the display colors “R”, “G”, and “B” of the pixel circuits 11. Will be particularly serious. In consideration of such circumstances, the configuration of the present embodiment that can suppress the variation in the luminance characteristics of each display color is provided with, for example, an electrostatic protection circuit, an inspection circuit, and the like in the capacitance adjustment area A. This is particularly effective when the interval is small.

  Further, when the data line driving circuit 30 is configured by an IC chip, the data lines 104 extend in the Y direction so as to be aggregated toward the data line driving circuit 30, so that the data lines 104 positioned in the capacity adjustment region A The interval may be smaller than the interval between the data lines 104 located in the pixel array unit 100. In this case, since the value of the parasitic capacitance of each data line 104 located in the capacitance adjustment area A becomes large, the variation in luminance characteristics of each display color becomes particularly serious. Even in such a case, the configuration of the present embodiment is effective.

  As a method of suppressing the variation in luminance characteristics of each display color, instead of adjusting the interval between the data lines 104 in the capacity adjustment region A, the relationship between the designated gradation and the gradation signal d output to the data line 104 However, according to the configuration of this embodiment, since it is not necessary to provide such a correction circuit, the data processing amount can be reduced and the configuration is simplified. There is an advantage.

<B: Second Embodiment>
FIG. 7 is a block diagram illustrating the configuration of the electro-optical device 10 according to the second embodiment of the invention. In the present embodiment, the display color of each pixel circuit 11 corresponding to the first data line 104 [1] of each block B and each pixel circuit 11 corresponding to the second data line 104 [2]. Is different from the first embodiment in that the display color of each pixel circuit 11 corresponding to the data line 104 [3] in the third column is “G”. The other configuration is the same as that of the first embodiment (for example, the interval between the data lines 104 in the capacity adjustment region A is the same as that of the first embodiment), and thus the description of the overlapping portions is omitted.

  As shown in FIG. 8, the pixel (display unit) C is composed of two pixel circuits 11 having “R” as a display color and one pixel circuit 11 having “G” as a display color. One pixel C displays a single color of “R” and “G” or a color corresponding to a mixture of “R” and “G”. With respect to “R”, the gradation of the two pixel circuits 11 in one pixel C is individually controlled (a kind of area control). Therefore, compared to a configuration in which only one “R” pixel circuit 11 is provided in one pixel C, a wide change range of gradation regarding “R” is ensured.

  Here, since the variation in the luminance characteristics between the same display colors is more easily perceived by the observer than the variation in the luminance characteristics between the different display colors, the variation in the luminance characteristics between the same display colors is the luminance between the different display colors. It is desirable that it be smaller than the variation in characteristics. According to the present embodiment, the luminance characteristic of “R” displayed by the pixel circuit 11 corresponding to the data line 104 [1] and the luminance characteristic of “R” displayed by the pixel circuit 11 corresponding to the second data line 104. Since the variation in characteristics can be made smaller than the variation in luminance characteristics between “R” and “G”, there is an advantage that it is possible to suppress a decrease in display quality of the electro-optical device 10.

<C: Third Embodiment>
FIG. 8 is a circuit diagram showing a configuration of a portion related to driving of the data line 104 in the electro-optical device 10 according to the third embodiment of the present invention. As shown in FIG. 8, in the present embodiment, the plurality of data lines 104 include six adjacent lines (104 [1], 104 [2], 104 [3], 104 [4], 104 [5]. , 104 [6]) are divided into n blocks B (B1, B2,... Bn). Of the six data lines 104 included in each block B, the display color of the pixel circuit 11 corresponding to each of the data line 104 [1] in the first column and the data line 104 [4] in the fourth column is “ R ". The display color of the pixel circuit 11 corresponding to each of the data line 104 [2] in the second column and the data line 104 [5] in the fifth column is “G”. Further, the display color of the pixel circuit 11 corresponding to each of the data line 104 [3] in the third column and the data line 104 [6] in the sixth column is “B”.

  FIG. 8 illustrates the k-th selection unit 50 corresponding to the block Bk. Each of the six switching elements 51 in the selection unit 50 in the k-th stage is interposed between the image signal line 106 and the data line 106 in the k-th stage and controls the electrical connection between them. The switching element 51 at the i-th stage (i = 1 to 6) of each block B is controlled by the sampling signal Si. For example, the first stage switching element 51 is controlled by the sampling signal S1 supplied to the sampling signal line 41a, and the second stage switching element 51 is controlled by the sampling signal S2 supplied to the sampling signal line 41b. Condition.

  FIG. 9 is a timing chart showing the operation of the electro-optical device 10. As shown in FIG. 9, the horizontal scanning period H in which one scanning line 102 is selected has a precharge period Tp and a first period T1 to a sixth period T6.

  As shown in FIG. 9, during the precharge period Tp, the sampling signals S1 to S6 are simultaneously shifted to the high level, and the precharge potential Vp is supplied to all the data lines 104 all at once. As in the above-described embodiments, the precharge potential Vp is a potential corresponding to the intermediate gradation.

  As in the first embodiment, the gradation signal d supplied to the image signal line 106 is supplied to the data line 104 [i] of each block B during the period in which the sampling signal Si is maintained at the active level. The As shown in FIG. 9, the sampling signals S1 to S6 are sequentially set to the active level in the order of S1, S4, S2, S5, S3, and S6 in the periods T1 to T6. Accordingly, the six data lines 104 [1] to 104 [6] in each of the n blocks B have 104 [1] → 104 [4] → 104 [2] → 104 [5] → 104 [3]. ] → 104 [6], the potentials (VR, VR ′, VG, VG ′, VB, VB ′) of the gradation signal d are supplied in a time division manner. For example, in FIG. 9, the potential VR is supplied to the data line 104 [1] in the first period T1, the potential VR ′ is supplied to the data line 104 [4] in the second period T2, and in the third period T3. Thus, the potential VG is supplied to the data line 104 [2]. On the other hand, as in the first embodiment, the sampling signal Si maintains the low level in a period other than the precharge period Tp and the period T (any one of T1 to T6) in which the sampling signal Si transitions to the high level. In this period, the data line 104 [i] is in an electrically floating state. For example, the data line 104 [1] is in an electrically floating state in a period other than the precharge period Tp and the first period T1, and the data line 104 [2] is electrically in a period other than the precharge period Tp and the third period T3. In other words, the data line 104 [3] is in an electrically floating state in a period other than the precharge period Tp and the fifth period T5.

  Here, since a parasitic capacitance is attached between the adjacent data lines 104, in FIG. 8, the data line 104 [1] of the block Bk is capacitively coupled to the data line 104 [2] of the block Bk. This is capacitively coupled to the data line 104 [6] in the sixth column of the block Bk-1 (not shown) adjacent to the negative side in the X direction when viewed from the block Bk. The data line 104 [2] of the block Bk is capacitively coupled to the data lines 104 [1] and 104 [3] of the block Bk.

  The data line 104 [4] of the block Bk is capacitively coupled to the data line 104 [3] and the data line 104 [5] of the block Bk. Further, the data line 104 [5] of the block Bk is capacitively coupled to the data line 104 [4] and the data line 104 [6] of the block Bk.

  Now, the potential VR supplied to the data line 104 [1] in the first period T1 and the potential VR ′ supplied to the data line 104 [4] in the second period T2 are set to the potential Vg ( = Vp), and the potential VG supplied to the data line 104 [2] in the third period T3 and the potential VG 'supplied to the data line 104 [5] in the fourth period T4 correspond to the black gradation. And the potential VB supplied to the data line 104 [3] in the fifth period T5 and the potential VB ′ supplied to the data line 104 [6] in the sixth period T6 are set to the potential Vm. Think.

  Since each data line 104 is in an electrically floating state other than the period T (T1 to T6) in which the gradation signal d is supplied to itself, it is supplied and held in the data line 104 [i] in the period T. The data potential fluctuates due to the parasitic capacitance between the data lines 104 at the time when the gradation signal d is supplied to another data line 104 adjacent to the data line 104 [i].

  For example, as shown in FIG. 9, at the time t3 when the potential Vm (VG) is supplied to the data line 104 [2], the potential Vg held in the data line 104 [1] in the first period T1 is changed to the data line 104 [2]. 104 [2] fluctuates by a change amount ΔV11 corresponding to the change amount of the potential (Vp → Vm). Similarly, at time t4 when the potential of the data line 104 [5] changes (Vp → Vm), the potential of the data line 104 [4] varies by ΔV12 from the potential Vg set in the second period T2. . Further, at the time t5 when the potential of the data line 104 [3] changes (Vp → Vm), the potential of the data line 104 [2] varies by ΔV13 from the potential Vm set in the third period T3. The potential of the data line 104 [4] varies by Δ14 from the immediately preceding potential Vg−Δ12. Further, at time t6 when the potential of the data line 104 [6] of the block Bk changes (Vp → Vm), the potential of the data line 104 [5] is ΔV15 from the potential Vm set in the fourth period T4. At the same time, the potential of the data line 104 [1] of the block Bk + 1 changes from the previous potential Vg−ΔV11 by ΔV16.

  As described above, the number of times that the potential set according to the gradation signal d fluctuates due to the change in potential of the other data line 104 after the setting is determined is the data line 104 [1] and the data line 104 [4]. Is twice, while the data line 104 [2] and the data line 104 [5] are once.

  Accordingly, the luminance characteristic of “R”, which is the display color of the pixel circuit 11 corresponding to each of the data line 104 [1] and the data line 104 [4], the data line 104 [2], and the data line 104 [5]. Luminance characteristic of “G”, which is the display color of the pixel circuit 11 corresponding to each of the data lines 104, and “B”, which is the display color of the pixel circuit 11 corresponding to each of the data lines 104 [3] and 104 [6]. There arises a problem that variation occurs between the luminance characteristics of the two. In this embodiment, the interval between the data lines 104 is adjusted in the capacity adjustment region A in order to suppress variations in the luminance characteristics of the display colors. Hereinafter, specific contents will be described.

  In this embodiment, as shown in FIG. 10, in each block B, the data line 104 [1] and the data line 104 [2] are adjacent to each other with an interval L1, and the data line 104 [4] and the data line It is adjacent to 104 [5] with an interval L1. The data line 104 [2] and the data line 104 [3] are adjacent to each other with an interval L2, and the data line 104 [5] and the data line 104 [6] are adjacent to each other with an interval L2.

  Further, as shown in FIG. 10, the interval L3 between the data line 104 [1] in the block Bk + 1 and the data line 104 [6] in the block Bk is the data line 104 [5] and data line 104 [6] in the block Bk. ] Is larger than the interval L2. Further, the interval L3 between the data line 104 [3] and the data line 104 [4] in the block Bk is larger than the interval L2 between the data line 104 [2] and the data line 104 [3] in the block Bk. A relationship of L2 + L3 = 2L1 is established between the intervals L1, L2, and L3. That is, as shown in FIG. 11, the positions of the data lines 104 [3] and 104 [6] in the respective proportional blocks B in which the data lines 104 are arranged at equal intervals L1 are represented by a distance ΔL (L1- 10 shifted to the negative side in the X direction by ΔL = L2, L1 + ΔL = L3) is the aspect of FIG. These relationships are the same in the other blocks B.

  From another point of view, in FIG. 10, two data lines adjacent to both sides of the data line 104 [1] of the block Bk + 1 (the data line 104 [2] of the block Bk + 1 and the data line 104 [6] of the block Bk) ) Interval L1 + L3 is larger than the interval L1 + L2 between two data lines 104 adjacent to both sides of the data line 104 [2] of the block Bk + 1 (the data line [1] 104 and the data line 104 [3] in the block Bk + 1). The interval L1 between the data line 104 [2] in the block Bk + 1 and the data line 104 [1] of the block Bk + 1 selected before the selection of the data line 104 [2] is the same as the data line 104 [2] of the block Bk + 1. It is larger than the interval L2 between the data line 104 [3] of the block Bk + 1 selected after the selection of the data line 104 [2].

  The interval L1 + L3 between two data lines adjacent to both sides of the data line 104 [4] (data line 104 [3] and data line 104 [5]) is 2 adjacent to both sides of the data line 104 [5]. Data line 104 (data line 104 [4] and data line 104 [6]) is larger than the interval L1 + L2, and is selected before the data line 104 [5] and the data line 104 [5] are selected. An interval L1 between the data line 104 [4] and the data line 104 [6] selected after the data line 104 [5] is selected is larger than an interval L2 between the data line 104 [5] and the data line 104 [5].

  As described above, in the present embodiment, the interval L3 between the data line 104 [1] and the data line 104 [6] adjacent to the negative side in the X direction when viewed from the data line 104 [1] is proportional. Since the value is larger than the other, the value of the parasitic capacitance Cx between the two is smaller than the proportionality. Therefore, the change amount ΔV16 of the potential of the data line 104 [1] linked to the change of the potential of the data line 104 [6] (Vp → Vm) at the time point t6 in the sixth period T6 is smaller than the proportionality. Similarly, since the distance L3 between the data line 104 [4] and the data line 104 [3] adjacent to the data line 104 [4] is also larger than the proportionality, the data line 104 at the time point t5 in the fifth period T5. The amount of change ΔV14 in the potential of the data line 104 [4] linked to the change in potential [3] (Vp → Vm) is smaller than the proportionality.

  In this embodiment, since the distance L2 between the data line 104 [2] and the data line 104 [3] is smaller than the proportionality, the distance between the data line 104 [2] and the data line 104 [3] The value of the parasitic capacitance Cy associated with is larger than the proportionality. Therefore, the amount of change ΔV13 in the potential of the data line 104 [2] in conjunction with the change in the potential of the data line 104 [3] at the time point t5 in the fifth period T5 is larger than the proportionality. Similarly, since the interval L2 between the data line 104 [5] and the data line 104 [6] is also smaller than the proportionality, it is linked with the change in the potential of the data line 104 [6] at the time point t6 in the sixth period T6. The amount of change ΔV15 in the potential of the data line 104 [5] is larger than the proportionality.

  That is, according to the present embodiment, the total potential change amount (= ΔV11 + ΔV16) of the data line 104 [1] in which the potential of the data line 104 fluctuates twice or the potential change amount of the data line 104 [4]. Of the data line 104 [2] in which the potential of the data line 104 changes only once (= ΔV13) or the potential change amount of the data line 104 [5] (= The difference from Δ15) can be made smaller than the proportionality. Therefore, the luminance characteristic of “R”, which is the display color of the pixel circuit 11 corresponding to each of the data line 104 [1] and the data line 104 [4], and the data line 104 [2] and the data line 104 [5]. Variations in luminance characteristics of “G”, which is the display color of the pixel circuit 11 corresponding to each, can be suppressed as compared with the proportionality.

<D: Modification>
The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible. Also, two or more of the modifications shown below can be combined.

(1) Modification 1
In each of the above-described embodiments, a mode in which the data lines 104 are divided into blocks B and a mode in which the data lines 104 are divided into blocks B are exemplified. The number of data lines 104 is arbitrary. The order of selecting the data lines 104 belonging to each block B is also arbitrary.

  In short, the electro-optical device 10 according to the present invention includes the first data line 104 (for example, the data line 104 [1] of the block Bk + 1 shown in FIG. 3) in which the data potential varies twice, and the data potential varies only once. The second data line 104 (for example, the data line 104 [2] of the block Bk shown in FIG. 3) is disposed between the first data line 104 and the second data line 104 and is adjacent to both the data lines 104. And the third data line 104 selected after the selection of the second data line 104 (for example, the data line 104 [3] of the block Bk shown in FIG. 3), and in the capacity adjustment region A, The interval (for example, L3 shown in FIG. 3) with respect to the third data line 104 may be larger than the interval (for example, L2 shown in FIG. 3) between the second data line 104 and the third data line 104.

  From another point of view, the electro-optical device 10 according to the present invention includes the first data line 104 (for example, the data line of the block Bk + 1 shown in FIG. 3) selected before the selection of the two data lines 104 adjacent to both sides. 104 [1]) and the second data line (for example, data of block Bk + 1 shown in FIG. 3) selected after the selection of the data line 104 adjacent to one side and before the selection of the data line 104 adjacent to the other side. The interval between two data lines 104 adjacent to both sides of the first data line 104 in the capacitance adjustment region A (for example, L1 + L3 shown in FIG. 3) is the second data line 104. Is larger than the interval between two data lines 104 adjacent to both sides of the data line (for example, L1 + L2 shown in FIG. 3), and adjacent to the second data line 104 and the second data line 104 on one side (for example, FIG. 3 The data line 104 (for example, L1 shown in FIG. 3) between the block Bk + 1 and the data line 104 adjacent to the other side of the second data line 104 (for example, FIG. As long as it is larger than the interval (for example, L2 shown in FIG. 3) with the data line 104 [3]) of the block Bk + 1 shown in FIG.

(2) Modification 2
In each of the above-described embodiments, the mode in which the interval between the data lines 104 is adjusted in the region A between the pixel array unit 100 and the data line driving circuit 30 is illustrated. The space between the data lines 104 may be adjusted in a region opposite to the data line driving circuit 30 with the array unit 100 interposed therebetween. This aspect is particularly effective when an electrostatic protection circuit, an inspection circuit, or the like is provided in a region on the opposite side of the data line driving circuit 30 with the pixel array unit 100 interposed therebetween so that the interval between the data lines 104 is reduced. is there.

  Further, when a resistance is associated with each data line 104, the waveform of the gradation signal d becomes duller (potential decreases) as the position of the data line 104 is farther from the data line driving circuit 30. As described above, when the potential drop of each data line 104 is assumed, the gradation signal d before the dulling is suppressed rather than the fluctuation of the potential of the data line 104 due to the fluctuation in the potential of the gradation signal d after the dulling. From the viewpoint of suppressing variation in gradation characteristics for each data line 104, it is more effective to suppress the fluctuation in the potential of the data line 104 due to the potential fluctuation. From the above viewpoint, each data in the capacitance adjustment region A shown in FIG. 1 is more than in the mode in which the interval between the data lines 104 is adjusted in the region opposite to the data line driving circuit 30 across the pixel array unit 100. It can be said that the mode of adjusting the interval between the lines 104 is more preferable.

(3) Modification 3

However, the present invention is not limited to this, and may be, for example, an organic EL element or an inorganic light emitting diode. In short, any element may be used as long as it emits light with light emission luminance corresponding to the applied electric energy.
