Description

Technical Field

[0001] The present invention relates to a self-luminous display device, in particular to a micro light emitting diode display device. Background Art

[0002] In a general self-luminous display device (such as OLED, LED), a display area and a non-display area are included; wherein the display area is provided with a driving circuit, and the display area includes a plurality of pixel areas, a plurality of scanning lines and a plurality of data lines arranged in a matrix. Each of the pixel areas includes three sub-pixels of different colors (red light, green light, blue light), and each of the sub-pixels uses scanning lines and data lines to control the light emission to present an image. In more detail, the data lines are connected by a driving circuit located in the non-display area, and the output data signal of the light-emitting element of the corresponding sub-pixel area is determined according to the content of each pixel in the image to be displayed, that is, the light emission of the light-emitting element is driven and controlled by the current size. In order to meet the high brightness requirements, the above-mentioned self-luminous display device increases the voltage supplied to the light-emitting element according to the voltage and current characteristic curve of the light-emitting element, so as to increase its conduction current and improve its light brightness; however, the increased conduction current will generate an excessively large load on the driving circuit, thereby increasing the overall power consumption; therefore, it is necessary to further improve the existing method of improving the display brightness of the self-luminous display device. Summary of the invention

[0003] In view of the above technical shortcomings of the existing self-luminous display device, the main purpose of the present invention is to provide a micro light emitting diode display device with high brightness display.

[0004] The main technical means used to achieve the above purpose is to make the micro light emitting diode display device include:

[0005] A plurality of pixel regions are arranged in an n*m matrix to form n row pixel regions and m column pixel regions; each pixel region comprises k parallel sub-pixel regions, and each sub-pixel region is provided with j micro-LEDs of different colors;

[0006] A display driving circuit is electrically connected to each of the pixel regions and includes a first driving mode and a second driving mode; wherein:

[0007] In the first driving mode, the display driving circuit sequentially enables the n rows of pixel regions, and when one row of pixel regions is to be enabled, controls one sub-pixel region of each pixel region on the enabled row of pixel regions to display a color; and

[0008] In the second driving mode, the display driving circuit enables the n rows of pixel regions in sequence, and when one row of pixel regions is to be enabled, the k sub-pixel regions of each pixel region on the enabled row of pixel regions are controlled to display the same color simultaneously.

[0009] From the above description, it can be seen that the micro-light emitting diode display device of the present invention mainly controls the k sub-pixel areas of each pixel area of ​​the enabled row pixel area to display the same color at the same time under the second driving mode by the display driving circuit. Compared with the first driving mode in which only one sub-pixel area of ​​each pixel area of ​​the enabled row pixel area displays one color, the overall brightness can be greatly improved to meet the demand for high-brightness display. Therefore, the present invention does not need to increase the current to improve the display brightness, which can avoid excessive power consumption.

[0010] The main technical means used to achieve the above purpose is to make another micro light emitting diode display device include:

[0011] A plurality of pixel groups are arranged in an n*m matrix to form n row pixel groups and m column pixel groups; each of the pixel groups comprises k parallel pixel regions, and each of the pixel regions is provided with j micro light emitting diodes of different colors;

[0012] A display driving circuit is electrically connected to each pixel group and includes a first driving mode and a second driving mode; wherein:

[0013] In the first driving mode, the display driving circuit sequentially outputs a scanning signal to the n*k row pixel regions so that the n*k row pixel regions are sequentially enabled, and outputs an image data signal to each enabled pixel region to display a color; and

[0014] In the second driving mode, the display driving circuit enables the n row pixel groups in sequence, and when one of the row pixel groups is enabled, it simultaneously outputs a scanning signal to the k pixel regions of each of the pixel groups on the enabled row pixel group, and outputs an image data signal to the k pixel regions to display the same color.

[0015] From the above description, it can be seen that the micro-light emitting diode display device of the present invention mainly consists of the display driving circuit in the second driving mode, which simultaneously sends a scanning signal to the k pixel areas of the enabled pixel group, and sends the same image data signal to the k pixel areas, so that the k pixel areas display the same color. Compared with the first driving mode in which only a single pixel area is controlled to display a specific color, the overall brightness can be greatly improved to meet the demand for high-brightness display; therefore, the present invention does not need to increase the current to improve the display brightness, which can avoid excessive power consumption.

[0047] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0048] First see Figure 1 and Figure 2A , which is the first embodiment of the micro light emitting diode display device of the present invention, comprises a plurality of pixel regions 10 and a display driving circuit 30 ; wherein the display driving circuit 30 is electrically connected to the pixel regions 10 to drive the pixel regions 10 .

[0049] The above-mentioned multiple pixel regions 10 are arranged in an n*m matrix to form n rows of pixel regions 11 and m columns of pixel regions 12. Each pixel region 10 includes k parallel sub-pixel regions 20, and each sub-pixel region 20 is provided with j groups of micro-LEDs of different colors to adjust the color of the displayed image. In this embodiment, the spacing between adjacent pixel regions 10 is less than 100μm, and the size of each micro-LED 100a, 100b, 100c is less than 30μm. Figure 2AAs shown, the first embodiment of each pixel region 10 of the present invention includes 4 sub-pixel regions (k=4), and each sub-pixel region 20 includes 3 (j=3) micro-light emitting diodes 100a, 100b, 100c of different colors, and is electrically connected to a scan line 311; and each of the pixel regions 10 having the same color of micro-light emitting diodes 100a, 100b, 100c is electrically connected to a data line 321; preferably, each sub-pixel region 20 includes at least red, green and blue micro-light emitting diodes 100a, 100b, 100c (j=3), that is, in this embodiment, the micro-light emitting diodes 100a, 100b, 100c composed of the array are connected to the same scan line 311 in the row direction and to the same data line 321 in the column direction, so each pixel region 10 of this embodiment includes 4 scan lines and 3 data lines. As shown in FIG. Fig. 7A As shown, in this embodiment, the two electrodes of each of the micro-LEDs 100a, 100b, 100c can be directly electrically connected to the corresponding scan line 311 (VS) and the data line 321 (VD). Figure 7B As shown, one electrode of each of the micro-LEDs 100a, 100b, 100c is electrically connected to the corresponding scan line 311 and data line 321 and a first potential (high potential end VDD) of a system power supply through a pixel driving circuit 101, and the other electrode is connected to a second potential (low potential end VSS) of the system power supply. The pixel driving circuit can be a 2T1C driving circuit, that is, it includes two transistors TD, TS and a storage capacitor CS, and can also adopt 3T1C, 6T2C and other similar driving circuits.

[0050] The display driving circuit 30 includes a scanning module 31 and a data module 32. Figure 2A As shown, the scanning module 31 is electrically connected to k scanning lines 311 of each row pixel region 11, and the data module 32 is electrically connected to at least three data lines 321 of each column pixel region 12. The display driving circuit 30 includes a first driving mode and a second driving mode.

[0051] In the first driving mode, please refer to Figure 2BAs shown, the display driving circuit 30 sequentially enables the n rows of pixel areas 11 in a frame period through the scanning module 31. When one of the row of pixel areas 11 is to be enabled, the scanning module 31 can select the scanning line 311 of one of the sub-pixel areas 20 of each pixel area 10 on the row of pixel area 11 to output a scanning signal, that is, only one of the sub-pixel areas 20 is enabled (less than k sub-pixel areas 20 can also be enabled), and an image data signal is output to each of the enabled sub-pixel areas 20 through the data module 32 to display the color of the corresponding image data. In this embodiment, since each pixel region 10 includes k sub-pixel regions 20, if the display driving circuit 30 only selects to enable one row of pixel regions 11, the display driving circuit 30 will sequentially output n scanning signals in one frame cycle; at this time, the display driving circuit 30 outputs m*j image data signals to the enabled sub-pixel regions 20 through the data module 32.

[0052] In addition, the micro-LED display device of the present embodiment can improve the resolution of the display screen in the first driving mode (for example, the number of pixels in the first display mode of the present embodiment is (n*k)*m) to present a finer display screen. For example, if the resolution of the display screen is to be improved, the n rows of pixel regions 11 are sequentially enabled in a frame period, and the scanning module 31 can be controlled to sequentially send a scanning signal S1-S4 to 4 (k=4) scanning lines 311 to sequentially enable each of the 4 groups of sub-pixel regions 20 in the same pixel region 10, so that the display driving circuit 30 sequentially outputs n*k scanning signals in a frame period, and then the display driving circuit 30 outputs m*j image data signals to the enabled sub-pixel regions 20 through the data module 32 to display a (n*k)*m development screen.

[0053] In the above second driving mode, please refer to Figure 2C As shown, the display driving circuit 30 sequentially enables the n rows of pixel regions 11 through the scanning module 31. When one row of pixel regions 11 is to be enabled, the scanning module 31 simultaneously outputs a scanning signal S11-S14 to the k scanning lines 311 of the k sub-pixel regions 20 of each pixel region 10 on the enabled row of pixel regions 11, and outputs an image data signal to the k sub-pixel regions 20 enabled at the same time to display the same color. That is, the k sub-pixel regions 20 of each pixel region 10 receive the same image data signal. In the second display mode, the display brightness of each pixel region 10 can be increased by k times without increasing the driving current load.

[0054] The image data signal output by the data module 32 in the above-mentioned first driving mode and second driving mode may include at least 3 constant current adjustment period signals, or include 3 variable current signals, so that at least 3 micro-light emitting diodes 100a, 100b, and 100c of different color lights in the sub-pixel area 20 that receives the image data signal respectively emit predetermined grayscale colors to be mixed into color lights corresponding to the image data.

[0055] See also Figure 3 FIG. 1 is a second embodiment of the micro light emitting diode display device of the present invention. Figure 1 The display device 30 is similar to the first embodiment, that is, it includes a plurality of pixel regions 10 and a display driving circuit 30; the difference is that the scanning module 31 including the display driving circuit includes k scanning units 310, which are respectively electrically connected to the k scanning lines 311 of each pixel region 10 in the n-row pixel region 11. For example, the first scanning unit 310 is connected to the first scanning lines 311 of the pixel regions 10, the second scanning unit 310 is connected to the second scanning lines 311 of the pixel regions 10, and the k-th scanning unit 310 is connected to the k-th scanning lines 311 of the pixel regions 10. In this embodiment, k scanning units 310 can be selected to be turned on at the same time. In the second display mode, if k scanning units 310 are turned on at the same time and have the same timing signal, scanning signals are output to the k scanning lines 311 of the k sub-pixel regions 20 of each pixel region 10 at the same time, thereby increasing the brightness by k times. In the first driving mode, the k scanning units 310 have staggered timing signals to output scanning signals in a time-sharing manner, thereby further improving the display resolution.

[0056] Please see again Figure 4A , which is a second embodiment of each pixel region 10 of the present invention, comprises k sub-pixel regions 20, each of which comprises micro-LEDs 100a, 100b, 100c with different colors of light. Figure 2A The difference of the embodiment of the pixel area 10 shown is that all the pixel areas 10 on each row of pixel areas 11 are connected to a common scan line 311, and all the pixel areas 10 on each column of pixel areas 12 are connected to j*k data lines 321, that is, all the micro-light emitting diodes 100a, 100b, 100c of different colors in the k sub-pixel areas 20 of each pixel area 10 are electrically connected to a common scan line 311, but are electrically connected to a data line 321 respectively; preferably, each group of micro-light emitting diodes 100a, 100b, 100c of different colors includes at least red, green and blue micro-light emitting diodes, so each row of pixel areas 11 of the present embodiment includes 1 scan line 311, and each column of pixel areas 12 includes 12 data lines 321.

[0057] In the first driving mode of the present embodiment, when a display driving circuit 30 is to enable one of the rows of pixel regions 11, Figure 4B As shown, the scanning module 31 outputs a scanning signal S1, S2, S3 ... or Sn to the single scanning line 311 of the row pixel area 11, so that the k sub-pixel areas 20 of the same pixel area 10 can be enabled at the same time, and the data module 32 selects j data lines (in this embodiment, j=3) corresponding to at least one of the sub-pixel areas 20, and outputs an image data signal to it, so that one of the sub-pixel areas 20 of the enabled pixel area 10 displays the color of the corresponding received image data signal; in this way, an image screen with a resolution of n*m can be displayed in one frame cycle. If the resolution of the image screen is to be further improved to (n*k)*m, the data module 32 can output corresponding image data signals to the k sub-pixel areas 20 during the period of enabling the pixel area 10, so that each sub-pixel area 20 displays the corresponding color.

[0058] In the second driving mode of the present embodiment, when the display driving circuit 30 is to enable one of the rows of pixel regions 11, as shown in FIG. Figure 4B As shown, a single scan line 311 of the row of pixel regions 11 outputs a scan signal S1, S2, S3 ... or Sn to simultaneously enable the k sub-pixel regions 20 in each pixel region 10, and then the data module 32 outputs the same image data signal to the enabled k sub-pixel regions 20, so that the enabled k pixel regions 20 simultaneously display the color of the corresponding received image data signal, and increase the brightness by k times. In other words, D1,1-D1,4 in each pixel region 10 outputs the same signal, D1,5-D1,8 outputs the same signal, and D1,9-D1,12 outputs the same signal, so that each pixel region 10 forms an image pixel point.

[0059] Depend on Figure 2A and Figure 4AIt can be seen that in the first driving mode, the display driving circuit 30 of the micro-LED display device of the present invention sequentially enables the n rows of pixel areas 11. When one of the rows of pixel areas 11 is to be enabled, one of the sub-pixel areas 20 of each of the pixel areas 10 of the row of pixel areas 111 is controlled to display a color as an image pixel point; and in the second driving mode, the display driving circuit 30 sequentially enables the n rows of pixel areas 11. When one of the rows of pixel areas 11 is to be enabled, one of the sub-pixel areas 20 of each of the pixel areas 10 of the row of pixel areas 111 is controlled to display a color as an image pixel point. The k sub-pixel regions 20 of each pixel region 10 of the pixel region 11 simultaneously output a scanning signal, and output an image data signal to the enabled sub-pixel regions 20 in the same row of pixel regions 11, so that the k sub-pixel regions 20 in each enabled pixel region 10 display the same color to form an image pixel point; therefore, the overall brightness of the micro-light emitting diode display device of the present invention in the second driving mode can be greatly improved to meet the demand for high-brightness imaging; therefore, the present invention does not need to increase the current to improve the imaging brightness, which can avoid excessive power consumption.

[0060] Please see again Figure 5 and Fig. 6A , which is the third embodiment of the micro light emitting diode display device of the present invention, comprises a plurality of pixel groups 40 and a display driving circuit 30; wherein the display driving circuit 30 is electrically connected to the pixel groups 40 to drive the pixel groups 40.

[0061] The above-mentioned multiple pixel groups 40 are arranged in an n*m matrix to form n rows of pixel groups 41 and m columns of pixel regions 42. Each pixel group 40 includes k parallel pixel regions 50, and each pixel region 50 is provided with 3 (j=3) micro-LEDs of different colors to adjust the color of the displayed image. In one embodiment, the spacing between adjacent pixel regions 10 is less than 100μm, and the size of each micro-LED 100a, 100b, 100c is less than 30μm. Fig. 6A As shown, an embodiment of each pixel group 40 of the present invention includes 4 pixel areas 50 (k=4), and the 4 pixel areas 10 are electrically connected to a scan line 311 respectively; and the micro-light emitting diodes 100a, 100b, 100c of different colors of light in these 4 pixel areas 50 are electrically connected to a data line 321 respectively; preferably, each group of micro-light emitting diodes 100a, 100b, 100c of different colors of light includes at least micro-light emitting diodes of red light, green light and blue light, so each row pixel group 41 of this embodiment includes 4 scan lines 311, and each column pixel area 42 includes 12 data lines 321.

[0062] The display driving circuit 30 includes a scanning module 31 and a data module 32. Fig. 6AAs shown, the scanning module 31 is electrically connected to k scanning lines 311 of each row pixel group 41, and the data module 32 is electrically connected to 12 data lines 321 of each column pixel group 31. The display driving circuit 30 includes a first driving mode and a second driving mode.

[0063] In the first driving mode, please refer to Figure 6B As shown, in a frame period, the display driving circuit 30 outputs a scanning signal S11~Sn4 to the n*k row pixel area 10 in sequence through the scanning module 31, so that the n*k row pixel area 10 is enabled in sequence, and outputs an image data signal to the enabled pixel areas 50 through the data module 32 to display a color corresponding to the image data.

[0064] In the second driving mode, in a frame period, the display driving circuit 30 sequentially enables the n row pixel groups 41. When one row pixel group 41 is to be enabled, Figure 6C As shown, a scanning signal S1-S4 is outputted to the k pixel regions 50 at the same time, and a same image data signal is outputted to the k pixel regions 10, so that the k pixel regions 50 in each enabled pixel group 40 display the same color; in this way, although the screen resolution of the micro-LED display device of this embodiment is reduced, the overall brightness of the screen can be improved to meet the demand for high-brightness display; in addition, since the k pixel regions 50 receive the scanning signal at the same time, compared with the first driving mode that sequentially outputs the scanning signal to the n*k rows of pixel regions 50, the frame cycle time of this embodiment is shortened to improve the frame update rate. Therefore, the resolution of the image in the first driving mode is higher than the resolution of the image in the second driving mode, but the brightness of the image in the first driving mode is lower than the brightness of the image in the second driving mode.

[0065] The image data signal of the above-mentioned data module includes different constant current adjustment cycle signals, or includes different variable current signals, so that the micro-light emitting diodes of different color lights in the pixel area receiving the image data signal emit predetermined grayscale colors to mix into the color lights corresponding to the image data.

[0066] In summary, the first embodiment of the present invention is mainly to make each pixel area include k side-by-side sub-pixel areas. If the display brightness is to be improved, all sub-pixel areas of each pixel area can be controlled to emit the same specific color light at the same time in the second brightness control mode to improve the overall brightness; and the second embodiment of the present invention is mainly to drive adjacent pixel areas (the same pixel group) at the same time to display the same specific color light in the second driving mode. Compared with only driving a single pixel area to emit a specific color light in the first driving mode, the overall brightness can be greatly improved to meet the needs of high-brightness display.

[0067] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
