Description

Technical Field

[0001] The present disclosure relates to flat panel displays, and in particular to a panel structure having data lines connected to different sub-pixels of the same color. Background Art

[0002] In recent years, flat panel displays have become larger and have been provided in new shapes. For example, the aspect ratio of displays for mobile devices has increased from 16:9 to 21:9. In addition, the refresh rate (i.e., frame rate) of these displays has increased. For example, the frame rate of displays for mobile devices has increased from 60 Hertz (Hz) to 120 Hz. These display trends correspond to increases in power consumption by the electrical circuitry that drives the displays.

[0003] When the length of the display increases, each column of the display includes additional pixels. All pixels in each column are controlled by signals carried by the column data lines. When the length of the display increases, these signals must have a higher switching frequency in order to control the additional pixels. In other words, in order to maintain (or increase) the frame rate while increasing the length of the display, a high column line switching frequency (e.g., >100 kHz) is required. In addition to the additional pixel circuits in the column signal lines increasing the capacitance of the data lines, the increase in switching frequency also linearly increases the dynamic power consumption in the drive circuit system. In addition, at these frequencies, the increased parasitic capacitance of each column data line can negatively affect the time constant associated with the switching of each pixel. Therefore, larger switching devices must be used, but larger switching devices require more power. Therefore, more power may be needed to achieve a high frame rate for a display with a high aspect ratio. The power consumption trends of some example displays are shown in Table 1.

[0039] Figure 1 An example of a mobile computing device (i.e., mobile device) is depicted. The front of the mobile device 100 is shown. The front includes a display 110 having an aspect ratio (AR), which is defined as the ratio of height 120 to width 130 (i.e., AR = height / width). The display 110 of the mobile device 100 can have a height (also known as length) 120 that is more than twice the width 130. For example, a high AR display can have an AR greater than 18.5 to 9.

[0040] Figure 2 Schematically depicts the Figure 1 The display system 200 includes a display panel (e.g., display 110) having light-emitting pixels and sub-pixels that are controlled by electronic pixel circuitry and / or sub-pixel circuitry to render visual output (e.g., text, graphics, video, images, etc.) on the display. Sub-pixels can be thought of as individual light-emitting elements, generally having a monochromatic light output, while pixels can be thought of as a combination of two or more light-emitting elements, where different elements have different colors, and thus the pixel can be controlled to output a range of colors. The display can be any active matrix display, such as an active matrix organic light-emitting diode (AMOLED) display.

[0041] An enlarged portion 210 of the display 110 is shown. The enlarged portion 210 illustrates the row / column configuration of the sub-pixels. In some embodiments, the device 110 can include more than 700 columns and more than 1300 rows. For example, the device can include at least 750 columns and at least 1334 rows. For example, the device can include at least 1080 columns and at least 1920 rows. The light emission of each sub-pixel 212 can be controlled by a scanning (gating) signal line 214 (i.e., a horizontal control line) and by a column data line 216 (i.e., a vertical control line). In some embodiments, and as Figure 2 As shown in , all sub-pixels in a row share can be driven by the same gating signal line, and all sub-pixels in a column can be driven by the same column data line. In some embodiments, as described in more detail below, all sub-pixels in a row can be driven by the same gating signal line, and sub-pixels of the same color but located in different columns can be driven by the same column data line. For example, a single column line can drive sub-pixels of a particular color located in odd-numbered rows of a column and can also drive sub-pixels of a particular color located in even-numbered rows of different columns.

[0042] The scan signal lines 214 of the display 110 are controlled by gate drivers 240. The column data lines are controlled by column line drivers 220. A timing controller (TC) 230 can control the signals to the scan line drivers 240 and the column line drivers 220 to ensure proper timing of the signals to the individual sub-pixels to achieve the desired light emission from the sub-pixels. The timing controller 230 can receive control signals from a system-on-chip including, for example, a central processing unit (CPU).

[0043] Sending electrical signals to the sub-pixels to control the emission of light from the sub-pixels involves alternating the voltage levels on the scan lines and column lines. As previously mentioned, higher frame rates and / or longer displays (i.e., higher AR displays) can result in a high switching frequency of the signals on the scan lines and column lines. This high frequency of voltage signal changes and the increased column line parasitic capacitance due to the high aspect ratio can result in excessive dynamic power consumption in the drive of the display panel. Therefore, when the column lines are connected to many pixels and / or when the display is operated at a high frame rate, it may be desirable to reduce / minimize the number of voltage level changes that are required in practice to program new image data into the pixels that display a new image on the screen.

[0044] Figure 3A Schematic diagram of a Pentile RGBG array 300 of subpixels of a first color, a second color, and a third color (e.g., red, green, and blue) in a display and circuitry for driving the subpixels. Each red, green, and blue subpixel can include an LED of a corresponding color. In each row of the Pentile RGBG array 300, a green subpixel 302 is interleaved with alternating red subpixels 304 and blue subpixels 306. Figure 3A As shown in , the green sub-pixel LED is shown by a dotted diamond; the red sub-pixel LED is shown by a horizontally striped diamond; and the blue sub-pixel LED is shown by a vertically striped diamond. Figure 3A , the circuits that drive the LEDs in the array are labeled with a capital letter corresponding to the color of the LED driven by the circuit and a two-digit index value, where the second digit of the index value indicates the row number of the driven LED (from top to bottom), and the first digit of the index value indicates the number of LEDs of a given color in the given row (from left to right). Thus, for example, the circuit labeled R11 drives the red LED in the top row and leftmost column; the circuit labeled G11 drives the green LED in the top row and second column; the circuit labeled R12 drives the red LED in the second row and third column from the top (which is the first red LED in the second row when proceeding from left to right); and so on.

[0045] The columns of the Pentile RGBG array 300 alternate between having all green sub-pixels 302 and having alternating red sub-pixels 304 and blue sub-pixels 306. For example, Figure 3A The leftmost column shown in includes subpixels alternating between red and blue, where the subpixels are driven by a voltage supplied by signal S1, and the column adjacent to the leftmost column includes all green subpixels driven by a voltage supplied by signal S2.

[0046] In the Pentile RGBG array 300, a pixel 308 of the display can be considered to include a combination of a red subpixel 304 and a green subpixel 302, or a combination of a blue subpixel 306 and a green subpixel 302. Thus, the pixels 300 in the Pentile RGBG array 300 can provide a color spectrum. Due to the dense packing of pixels in modern high-resolution displays, users are generally unable to perceive individual pixels 300, and the overall effect of the array 300 perceived by the user is that any color can emanate from anywhere on the display. Additionally, utilizing a Pentile RGBG array arrangement of subpixels, the number of subpixels for certain colors (e.g., red and blue) can be reduced compared to a conventional RGB stripe arrangement of subpixels (RGBRGB subpixels for two pixels), such that a display panel utilizing the Pentile RGBG array of subpixels uses one-third fewer subpixels than a conventional RGB stripe display having the same resolution. Consequently, a higher-resolution, brighter device can be implemented utilizing a Pentile RGBG array arrangement of subpixels.

[0047] Figure 3B is a timing diagram 320 illustrating the addressing of individual sub-pixels in the Pentile RGBG array 300. In the timing diagram 320, the state of scan line [1] 310 represents the voltage applied to the scan line that controls the sub-pixels in row 1; the state of scan line [2] 312 represents the voltage applied to the scan line that controls the sub-pixels in row 2; and the state of scan line [3] 314 represents the voltage applied to the scan line that controls the sub-pixels in row 3. The state of the scan line that controls the sub-pixels in row 4 is not shown in FIG. Figure 3B , but can be understood as an extension of lines 310, 312, and 314. The state of column line 316 represents the voltage applied to the column line that controls the sub-pixels in column 1; and the state of column line 318 represents the voltage applied to the column line that controls the sub-pixels in column 2. The states of the column lines that control the sub-pixels in columns 3 and 4 are not shown in FIG. Figure 3B , but can be understood as an extension from lines 316 and 318.

[0048] The states of the scan lines 310, 312, 314 and the states of the column line signals S1 and S2 indicate that the voltage on the individual scan lines 310, 312, 314 corresponding to rows 1, 2, and 3 switches between a high state and a low state within a fixed time period. When the voltage on the scan line for a row is "ON," which is when the scan line voltage level is low for the p-channel transistor switches in the pixel circuits, this allows the sub-pixel circuits in that row to be updated with new data voltages via the signals on the column lines for the sub-pixels in the ON row. When the signal on the scan line for a row is "OFF," which is when the scan line voltage level is high for the p-channel transistor switches in the pixel circuits, the sub-pixels in the row are disconnected from the column data lines and cannot be updated.

[0049] Figure 4A is a schematic top view of the connections between the electrical pixel circuitry and the light emitting sub-pixel elements of a display 400 having sub-pixels arranged in a Pentile RGBG array. Figure 4A As shown in FIG, a unit cell of the display can include a red light emitting area 402, a first green light emitting area 412, a blue light emitting area 422, and a second green light emitting area 432. The red light emitting area 402 and the first green light emitting area 412 together define a first pixel, and the blue light emitting area 422 and the second green light emitting area 432 together define a second pixel.

[0050] Each light emitting region 402, 412, 422, 432 is connected to a sub-pixel circuit 404, 414, 424, 434, respectively, which receives electrical signals, for example, from scan lines and column lines associated with the sub-pixel and converts the received signals into a current to be applied to the semiconductor material to drive the emission of light from the light emitting region of the sub-pixel. The sub-pixel circuit 404, 414, 424, 434 for a sub-pixel can be physically and electrically connected to the corresponding light emitting region 402, 412, 422, 432 of the sub-pixel through a corresponding pixel circuit output port 406, 416, 426, 436. The sub-pixel circuit output port 406, 416, 426, 436 can include a conductive material (e.g., a metal) that transmits the current signal from the sub-pixel circuit to the light emitting region.

[0051] Figure 4B is an example schematic cross-sectional view of a red sub-pixel 450 having an electrical sub-pixel circuit 452 for driving an LED 454. The electrical sub-pixel circuit 452 and the LED 454 are fabricated on a common substrate 453. The electrical sub-pixel circuit 452 includes a plurality of conductive, insulating, and semiconducting layers capable of functioning as transistors to supply drive current from the circuit 452 to the LED 454 in response to electrical signals received on scan and column lines for the sub-pixel 450. For example, Figure 4B Depicted are a metal layer for transistor gate electrodes 456 and scan line traces 458 and another metal layer 460 for interconnection between column data lines and electrodes in the sub-pixel circuits. The metal contacts 460 of the sub-pixel circuits 452 can be electrically connected to sub-pixel circuit output ports 460 that deliver drive current to the LEDs 454. The sub-pixel circuits include a plurality of electrical circuit elements, such as transistors and capacitors, and Figure 4B A portion of a circuit assembly is shown.

[0052] Figure 5 FIG2 is a schematic diagram of a layout 500 of light-emitting elements, subpixel circuits, and subpixel output ports in a Pentile RGBG array, wherein the subpixel output ports electrically connect the light-emitting elements to the subpixel circuits. The Pentile RGBG array includes rows 502A and 502B and columns 504A, 504B, 504C, 504D, 504E, 504F, 504G, and 504H of light-emitting elements and subpixel circuits. For example, the Pentile RGBG array can include red light-emitting elements 514AA, 514AE, 514BC, and 514BG; green light-emitting elements 514AB, 514AD, 514AF, 514AH, 514BB, 514BD, 514AB, and 514BH; and blue light-emitting elements 514AC, 514AG, 514BA, and 514BE. Different subpixel circuits in the same row are driven by signals on the same scan line, and different subpixel circuits in the same column are driven by signals on the same column line.

[0053] In the first row 502A, each subpixel circuit 512AA, 512AB, 512AC, 512AD, 512AE, 512AF, 512AG, 512AH is electrically connected to a corresponding light emitting element 514AA, 514AB, 514AC, 514AD, 514AE, 514AF, 514AG, 514AH located in the same row and column as the subpixel circuit. The subpixel circuits 512AA, 512AB, 512AC, 512AD, 512AE, 512AF, 512AG, 512AH are electrically connected to the light emitting elements 514AA, 514AB, 514AC, 514AD, 514AE, 514AF, 514AG, 514AH through subpixel output ports 516AA, 516AB, 516AC, 516AD, 516AE, 516AF, 516AG, 516AH, respectively.

[0054] In the second row 502B, each green light-emitting element 514BB, 514BD, 514BF, and 514BH is electrically connected (via corresponding sub-pixel output ports 516BB, 516BD, 516BF, and 516BH) to a corresponding sub-pixel circuit 512AB, 512AD, 512AF, and 512AH located in the same row and column as the green light-emitting element. However, in the second row 502B, blue light-emitting elements 514BA and 514BE, and red light-emitting elements 514BC and 514BG are not connected to a sub-pixel circuit located in the same column as the light-emitting element. Instead, the light-emitting elements of the first color are connected to a column number lower than the column number of the light-emitting element (i.e., Figure 5 ) of the sub-pixel circuit, and is composed of a column number lower than the column number of the light-emitting element (ie, Figure 5 The sub-pixel circuit of the left side of the ) is driven, and the light-emitting element of the second color is connected to a column number higher than the column number of the light-emitting element (ie, Figure 5 ) and consists of a sub-pixel circuit with a column number higher than the column number of the light-emitting element (ie, Figure 5 For example, Figure 5 As shown in the figure, the red sub-pixel elements 514BC and 514BG in the third and seventh columns of the array are connected to the sub-pixel circuits 512BA and 512BE in the first and fifth columns of the array, respectively, and the blue sub-pixel elements 514BA and 514BE in the first and fifth columns are connected to the sub-pixel circuits 512BC and 512BH in the third and seventh columns of the array, respectively.

[0055] This pattern can be repeated throughout an array of pixels in a Pentile RGBG display such that in alternating rows of the array: (1) each light-emitting element in the row is connected to and driven by a sub-pixel circuit in the same column as the light-emitting element, and (2) a light-emitting element of a first color is connected to and driven by a sub-pixel circuit in a column number lower than the column number of the light-emitting element, and a light-emitting element of a second color is connected to and driven by a sub-pixel circuit in a column number higher than the column number of the light-emitting element. For example, in odd rows, each light-emitting element of the row can be driven by a sub-pixel circuit in the same column as the light-emitting element, and in even rows, the light-emitting element of the first color (for example, red) can be connected to a sub-pixel circuit with a column number lower than the column number of the light-emitting element of the first color, and driven by a sub-pixel circuit with a column number lower than the column number of the light-emitting element of the first color, and the light-emitting element of the second color (for example, blue) can be connected to a sub-pixel circuit with a column number higher than the column number of the light-emitting element of the second color, and driven by a sub-pixel circuit with a column number higher than the column number of the light-emitting element of the second color.

[0056] In this layout, i.e., in which in every other row, the light-emitting elements of the first color are connected to sub-pixel circuits with column numbers lower than the column numbers of the light-emitting elements and are driven by sub-pixel circuits with column numbers lower than the column numbers of the light-emitting elements, and the light-emitting elements of the second color are connected to sub-pixel circuits with column numbers higher than the column numbers of the light-emitting elements and are driven by sub-pixel circuits with column numbers higher than the column numbers of the light-emitting elements, the sub-pixel output ports 516BA, 516BC, 516BE, 516BG connecting the sub-pixel circuits of one column to the light-emitting elements in another column extend over a distance greater than the width of one sub-pixel circuit.

[0057] because Figure 5 , wherein columns 504A, 504C, 504E, 504G of a Pentile RGBG array include light-emitting elements of alternating colors, and wherein, for alternating rows of the array, the light-emitting elements are driven by sub-pixel circuits located in different columns than the light-emitting elements being driven, and column lines can be connected to sub-pixel circuits that drive light-emitting elements of only one color. For example, a column line connected to sub-pixel circuits 512AA and 512BA located in column 504A can drive red light-emitting elements 514AA and 514BC, and a column line connected to sub-pixel circuits 512AC and 512BC located in column 504C can drive blue light-emitting elements 514AC and 514BA.

[0058] Because the column lines are connected to sub-pixel circuits that drive light-emitting elements of only one color, the number of times the voltage level of the column data lines changes during operation of the display can be reduced on average compared to conventional configurations in which column lines are connected to sub-pixels of light-emitting elements of different (or more) colors, thereby reducing power loss due to column line parasitic capacitance. Reduced voltage switching can be a result of having the column lines control light-emitting elements of only one color, so that in areas of the image on the display where the colors are relatively monotonous, there is no need to significantly switch the voltage signal on the signal line to send signals to different light-emitting elements in different rows but in the same column controlled by the column lines.

[0059] Figure 6 Schematic diagram of four columns and four rows of red, green, and blue light-emitting elements of an RGBG array display. The light-emitting elements are connected to sub-pixel circuits driven by signals S1, S2, S3, and S4, wherein each column line driven by S1, S2, S3, and S4 drives a light-emitting sub-pixel circuit connected to a light-emitting element of a single color (i.e., red, green, or blue), as described above with reference to FIG. Figure 5 Descriptive.

[0060] Figure 6A state is depicted in which the display outputs red light such that the red sub-pixel light emitting area is turned on and the green and blue sub-pixel light emitting areas are turned off. Figure 6 In FIG, the green sub-pixel LED and the blue sub-pixel LED are shown by black diamonds, and the red sub-pixel LED is shown by horizontally striped diamonds. Figure 6 , the circuits that drive the LEDs in the array are labeled with a capital letter corresponding to the color of the LED driven by the circuit and a two-digit index value, where the second digit of the index value indicates the row number of the driven LED (from top to bottom), and the first digit of the index value indicates the number of LEDs of a given color in the given row (from left to right). Thus, for example, the circuit labeled R11 drives the red LED in the top row and leftmost column; the circuit labeled G11 drives the green LED in the top row and second column; the circuit labeled R22 drives the red LED in the second row and third column from the top (which is the first red LED in the second row when proceeding from left to right); and so on.

[0061] Figure 7 It provides signals scan【1】, scan【2】 and scan【3】 and is used to provide Figure 6 Schematic timing diagram of the column line signals S1, S2 and S3 for all red outputs of the light emitting elements of the embodiment of the present invention. In order to provide all red outputs, the signal on the column line driven by the signal S1 is maximized to turn on the red light emitting elements connected to S1, while the signal on the column line driven by the signals S2 and S3 is minimized to turn off the green light emitting elements and the blue light emitting elements connected to the signals S2 and S3. In addition, as time goes by, the signals scan [1], scan [2] and scan [3] are sequentially switched between high level values and low level values to provide ON signals for red light emitting elements, OFF signals for green light emitting elements and OFF signals for blue light emitting elements to the corresponding red elements, green elements and blue elements of consecutive rows. As can be seen from Figure 7 As can be seen from the timing diagram of , when a monochrome output is displayed, the value of the signal provided on the column lines driven by S1, S2 and S3 is constant because the column lines are connected to sub-pixel circuits that drive light-emitting elements of the same color. In contrast, if alternating rows of columns driven by the "S1" signal are connected to light-emitting elements of alternating colors (for example, red and blue), the voltage on S1 will have to switch between maximum and minimum values as the new row is addressed by scan【1】, scan【2】 and scan【3】, and such frequent voltage changes will result in higher power losses due to parasitic capacitance on the column lines.

[0062] Figure 8FIG2 is a schematic diagram of another layout 800 of light-emitting elements, subpixel circuitry, and subpixel output ports in a Pentile RGBG array, wherein the subpixel output ports electrically connect the light-emitting elements to the subpixel circuitry. The Pentile RGBG array includes rows 802A and 802B and columns 804A, 804B, 804C, 804D, 804E, 804F, 804G, 804H, and 804I of light-emitting elements and subpixel circuitry. For example, the Pentile RGBG array can include red light-emitting elements 814AB, 814AF, 814BD, and 814BH; green light-emitting elements 814AC, 814AE, 814AG, 814AI, 814BC, 814BE, 814AC, and 814BI; and blue light-emitting elements 814AD, 814AH, 814BB, and 814BF. Different sub-pixel circuits in the same row are driven by signals on the same scan line, and different sub-pixel circuits in the same column are driven by signals on the same column line.

[0063] In the first row 802A, each subpixel circuit 812AB, 812AC, 812AD, 812AE, 812AF, 812AG, 812AH, and 812AI is electrically connected to a corresponding light-emitting element 814AB, 814AC, 814AD, 814AE, 814AF, 814AG, 814AH, and 814AI located in the same row and column as the subpixel circuit. Subpixel circuits 812AB, 812AC, 812AD, 812AE, 812AF, 812AG, 812AH, and 812AI are electrically connected to light-emitting elements 814AB, 814AC, 814AD, 814AE, 814AF, 814AG, 814AH, and 814AI through subpixel output ports 816AB, 816AC, 816AD, 816AE, 816AF, 816AG, 816AH, and 814AI, respectively. Row 802A also includes "dummy" sub-pixel circuitry 812AA that is not connected to any light-emitting element.

[0064] In second row 802B, each green light-emitting element 814BC, 814BE, 814BG, and 814BI is electrically connected (via corresponding subpixel output ports 816BC, 816BE, 816BG, and 816BI) to corresponding subpixel circuits 812AC, 812AE, 812AG, and 812AI, which are located in the same row and column as the green light-emitting elements via corresponding subpixel output ports 816AC, 816AE, 816AG, and 816AI. However, in second row 802B, blue light-emitting elements 814BB and 814BF, and red light-emitting elements 814BD and 814BH are not connected to subpixel circuits located in the same column as the light-emitting elements. In contrast, each light-emitting element of the first color (e.g., red) and the second color (e.g., blue) is connected to a sub-pixel circuit of a column number different from the column number of the light-emitting element and is driven by a sub-pixel circuit of a column number different from the column number of the light-emitting element. Figure 8 As shown in FIG, red sub-pixel elements 814BC and 814BG in the fourth and eighth columns of the array are connected to sub-pixel circuits 812BA and 812BE in the second and sixth columns of the array, respectively, and blue sub-pixel element 814BF in the sixth column is connected to sub-pixel circuit 812BD in the fourth column of the array. This pattern repeats throughout row 802B, where the light-emitting elements in column N are connected to and driven by, for example, a sub-pixel circuit in column N-2. A first light-emitting element 814BB of row 802B, adjacent to a sub-pixel circuit 812BA directly above or below a "dummy" sub-pixel circuit 812AA, can be connected to a sub-pixel circuit directly adjacent to light-emitting element 814BB.

[0065] This pattern can be repeated throughout the pixel array in a Pentile RGBG display such that in alternating rows of the array: (1) each light-emitting element of the row is connected to and driven by a sub-pixel circuit in the same column as the light-emitting element, and (2) each light-emitting element of the first color and the second color is connected to and driven by a sub-pixel circuit in a column number lower than the column number of the light-emitting element. For example, in odd-numbered rows, each light-emitting element of the row can be driven by a sub-pixel circuit in the same column as the light-emitting element, and in even-numbered rows, the light-emitting elements of the first color (e.g., red) and the second color (e.g., blue) can be connected to and driven by a sub-pixel circuit in a column number lower than the column number of the light-emitting element.

[0066] In such a layout, in which each light-emitting element of the first color and the second color in every other row is connected to a sub-pixel circuit with a column number lower than the column number of the light-emitting element and is driven by a sub-pixel circuit with a column number lower than the column number of the light-emitting element, the sub-pixel output ports 816BB, 816BD, 816BF, 816BH connecting the sub-pixel circuit of one column to the light-emitting elements of another column extend over a distance greater than the width of one sub-pixel circuit.

[0067] because Figure 8 , wherein columns 804B, 804D, 804F, and 804H of a Pentile RGBG array include light-emitting elements of alternating colors, and wherein, for alternating rows of the array, the light-emitting elements are driven by sub-pixel circuits located in a different column than the light-emitting elements being driven, and column lines are connected to sub-pixel circuits that drive light-emitting elements of only one color. For example, a column line connected to sub-pixel circuits 812AB and 812BB located in column 804B can drive red light-emitting elements 814AB and 814BD, and a column line connected to sub-pixel circuits 812AD and 812BD located in column 804D can drive blue light-emitting elements 814AD and 814BF.

[0068] As reference Figure 5 The configuration described, using Figure 8 The configuration of light-emitting elements, sub-pixel circuits, and sub-pixel output ports, wherein column lines are connected to sub-pixel circuits that drive light-emitting elements of only one color, enables the number of voltage switching on and off of the column lines to be reduced on average during operation of the display, compared to a conventional configuration in which column lines are connected to sub-pixels of light-emitting elements of different (more than one) colors, thereby reducing power loss due to parasitic capacitance of the column lines. The reduced voltage switching can result from having the column lines control light-emitting elements of only one color, so that in areas of an image on the display where the colors are relatively monotonous, it is not necessary to significantly switch voltage signals on the signal lines to send signals to different light-emitting elements in different rows but in the same column controlled by the column lines.

[0069] Figure 9 is a schematic diagram of five columns and four rows of red, green, and blue light-emitting elements of an RGBG array display, wherein the light-emitting elements are connected to and driven by sub-pixel circuitry in response to signals S0, S1, S2, S3, and S4 provided on corresponding column lines, wherein each column line S0, S1, S2, S3, and S4 provides a signal to circuit elements connected to light-emitting elements of a single color (i.e., red, green, or blue), as described above with reference to Figure 8 As stated.

[0070] like Figure 9As shown in , the green sub-pixel LED is shown by a dotted diamond; the red sub-pixel LED is shown by a horizontally striped diamond; and the blue sub-pixel LED is shown by a vertically striped diamond. Figure 9 , the circuits that drive the LEDs in the array are labeled with a capital letter corresponding to the color of the LED driven by the circuit and a two-digit index value, where the second digit of the index value indicates the row number of the LED being driven (from top to bottom), and the first digit of the index value indicates the number of LEDs of a specified color in the specified row (from left to right). Thus, for example, the circuit labeled R11 drives the red LED in the top row and second column from the left; the circuit labeled G11 drives the green LED in the top row and third column from the left; and the circuit labeled R12 drives the red LED in the second row from the top and fourth column from the left (which is the first red LED in the second row when proceeding from left to right). Additionally, for example, the circuit labeled B11 drives the blue LED in the top row and fourth column from the left; and the circuit labeled B12 drives the blue LED in the second row from the top and second column from the left.

[0071] Figure 10 The signals scan【1】, scan【2】 and scan【3】 are used to provide Figure 9 Schematic timing diagram of the output of column line signals S0, S1, S2, and S3 of the light-emitting elements of the column line. As can be seen from the timing diagram, the column lines S0, S1, S2, and S3 provide signals to the circuit elements to drive the light-emitting elements of a single color, so that in areas of the displayed image where the color and brightness do not change much from one row to the next (which is usually the case), the signals S0, S1, S2, and S3 on the column lines do not change much either. Therefore, the voltage of each of the column line signals S0, S1, S2, and S3 that turns on and off is reduced compared to a configuration in which light-emitting elements of more than one color are controlled by the column lines, thereby reducing parasitic capacitance and reducing power loss.
