Abstract
Description
Technical Field
[0001] This application belongs to the field of display technology, and specifically relates to a display device. Background Technology
[0002] Display devices include liquid crystal displays (TFT-LCDs), organic light-emitting diode displays (OLEDs), and electronic paper (ePaper). All display devices include a display panel and a gate driving module. The gate driving module controls the display panel to scan line by line to display the image and determines the refresh rate of the display panel.
[0003] Refresh rate is the number of times a screen updates its image per second. It determines the smoothness of the image, response speed, and visual comfort, and is one of the most critical parameters in display technology. Variable refresh rate technology can dynamically adjust the refresh rate of the display panel. When displaying highly dynamic images, increasing the refresh rate can reduce or eliminate motion blur and improve the display effect. When displaying static images, decreasing the refresh rate can reduce the power consumption of the display panel.
[0004] Partition refresh is an energy-saving and efficiency optimization technology for display panels. Its core principle is to divide the screen into multiple zones, applying different refresh rates to different zones to balance display quality and power consumption. However, significant differences in refresh rates between adjacent zones can easily lead to screen flickering and uneven brightness at zone boundaries, affecting the display device's performance.

[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.
[0030] Example 1 See Figure 1 As shown, in this embodiment, the display device includes a display panel 100, a control module 200, and a gate driving module 300. The display panel 100 includes multiple rows of scan lines 101, multiple columns of data lines 102, and multiple sub-pixels. The sub-pixels are located at the intersections of the scan lines 101 and the data lines 102. Each sub-pixel is connected to the scan line 101 of its row and the data line 102 of its column. The scan line 101 controls the activation of a row of sub-pixels, and the data signals on the multiple columns of data lines 102 are written to the multiple sub-pixels of a row to realize the display of a row of images. By scanning and activating all sub-pixels row by row, one frame of images can be displayed.
[0031] The gate driving module 300 includes a first gate driving unit 310 (GOA1) and a second gate driving unit 320 (GOA2). The display panel 100 includes a first vertical partition 111, a second vertical partition 114, and a vertical transition area. The first vertical partition 111 and the second vertical partition 114 are respectively disposed on both sides of the column direction of the vertical transition area. Multiple scan lines 101 of the first vertical partition 111 are connected to the first gate driving unit 310, and multiple scan lines 101 of the second vertical partition 114 are connected to the second gate driving unit 320.
[0032] The gate driving module 300 can control the refresh rate of the display panel 100, which is the number of times the display panel 100 updates the image per second. Specifically, the first gate driving unit 310 controls the refresh rate of the first vertical partition 111, and the second gate driving unit 320 controls the refresh rate of the second vertical partition 114; when the refresh rates of the first vertical partition 111 and the second vertical partition 114 are different, the display panel 100 can achieve partitioned refresh.
[0033] The control module 200 includes a first selection unit 210 and a first control unit 220. The first selection unit 210 is connected to the first gate driving unit 310, the second gate driving unit 320, the scan line 101 in the vertical transition region, and the first control unit 220. The first control unit 220 controls the first selection unit 210 to work, so that the first gate driving unit 310 and the second gate driving unit 320 alternately output scan signals to the scan line 101 in the vertical transition region.
[0034] If the refresh rate of the first vertical partition 111 is F1 and the refresh rate of the second vertical partition 114 is F2, and the refresh rates F1 and F2 are different, then the average refresh rate of the vertical transition zone is between F1 and F2 over a period of time.
[0035] When displaying high dynamic range images, increasing the refresh rate can reduce or eliminate motion blur and improve display quality. When displaying static images, decreasing the refresh rate can reduce the power consumption of the display panel 100. The display panel 100 uses zoned refresh, applying different refresh rates to different zones to balance display quality and power consumption. However, significant differences in refresh rates between adjacent zones can easily lead to screen flicker and uneven brightness at zone boundaries, affecting the display performance of the device.
[0036] In this embodiment, the display device includes a display panel 100, a control module 200, and a gate driving module 300. The display panel 100 includes multiple rows of scan lines 101 and multiple columns of data lines 102. The gate driving module 300 includes a first gate driving unit 310 and a second gate driving unit 320. The display panel 100 includes a first vertical partition 111, a second vertical partition 114, and a vertical transition region. The first vertical partition 111 and the second vertical partition 114 are respectively disposed on both sides of the column direction of the vertical transition region. The multiple scan lines 101 of the first vertical partition 111 are all connected to the first gate driving unit 320. The second vertical partition 114 is connected to the second gate driving unit 320. The control module 200 includes a first selection unit 210 and a first control unit 220. The first selection unit 210 is connected to the first gate driving unit 310, the second gate driving unit 320, the scan lines 101 in the vertical transition area, and the first control unit 220. The first control unit 220 controls the first selection unit 210 to work, so that the first gate driving unit 310 and the second gate driving unit 320 alternately output scan signals to the scan lines 101 in the vertical transition area. When the display panel 100 refreshes in partitions, the average refresh rate of the vertical transition area is between the two vertical partitions, that is, a smooth transition of refresh rate between the two vertical partitions is achieved, which can reduce or eliminate screen flicker and uneven brightness at the boundary of the vertical partitions and improve the display effect of the display device.
[0037] It should be noted that the display device includes a source drive module 400, which is connected to the multi-column data lines 102 of the display panel 100.
[0038] In some embodiments, the vertical transition region includes a first vertical sub-region 112, and the first selection unit 210 includes a first transistor 211 and a second transistor 212. The first transistor 211 and the second transistor 212 have different channel types; for example, the first transistor 211 is an N-channel field-effect transistor, and the second transistor 212 is a P-channel field-effect transistor, or vice versa.
[0039] The first terminal of the first transistor 211 is connected to the first gate driving unit 310, the second terminal of the first transistor 211 is connected to the scan line 101 in the first vertical sub-region 112, the first terminal of the second transistor 212 is connected to the second gate driving unit 320, the second terminal of the second transistor 212 is connected to the scan line 101 in the first vertical sub-region 112, and the control terminals of the first transistor 211 and the second transistor 212 are both connected to the first control unit 220.
[0040] When the first vertical sub-region 112 includes multiple scan lines 101, the number of first transistors 211 and second transistors 212 can be set accordingly to multiple, with multiple first transistors 211 connected in parallel and multiple second transistors 212 connected in parallel. That is, each scan line 101 in the first vertical sub-region 112 is connected to the first gate driving unit 310 through a first transistor 211, and each scan line 101 in the first vertical sub-region 112 is connected to the second gate driving unit 320 through a second transistor 212.
[0041] The first selection unit 210 includes a first transistor 211 and a second transistor 212. When the first transistor 211 is on and the second transistor 212 is off, the first vertical sub-region 112 is driven by the first gate driving unit 310. When the first transistor 211 is off and the second transistor 212 is on, the first vertical sub-region 112 is driven by the second gate driving unit 320. When the first transistor 211 and the second transistor 212 are alternately on, the average refresh rate of the vertical transition region is between the two vertical partitions. At the same time, by controlling the on-time ratio of the first transistor 211 and the second transistor 212 through the first control unit 220, the magnitude of the average refresh rate of the vertical transition region can be controlled.
[0042] See Figure 2 As shown, the vertical transition area includes a first vertical sub-area 112 and a second vertical sub-area 113, with the first vertical sub-area 112 located on the side of the second vertical sub-area 113 closest to the first vertical partition 111. That is, the first vertical partition 111, the first vertical sub-area 112, the second vertical sub-area 113, and the second vertical partition 114 are arranged sequentially along the column direction.
[0043] The first selection unit 210 includes a first transistor 211, a second transistor 212, a third transistor 213, and a fourth transistor 214. The first transistor 211 and the second transistor 212 have different channel types, and the third transistor 213 and the fourth transistor 214 have different channel types. For example, the first transistor 211 may be an N-channel field-effect transistor, and the second transistor 212 may be a P-channel field-effect transistor, or vice versa; the third transistor 213 may be an N-channel field-effect transistor, and the fourth transistor 214 may be a P-channel field-effect transistor, or vice versa. The first terminal of the first transistor 211 is connected to the first gate driving unit 310, and the second terminal of the first transistor 211 is connected to the scan line 101 of the first vertical sub-region 112. The first terminal of the second transistor 212 is connected to the second gate driving unit 320, and the second terminal of the second transistor 212 is connected to the scan line 101 of the first vertical sub-region 112. The first terminal of the third transistor 213 is connected to the first gate driving unit 310, and the second terminal of the third transistor 213 is connected to the scan line 101 of the second vertical sub-region 113. The first terminal of the fourth transistor 214 is connected to the second gate driving unit 320, and the second terminal of the fourth transistor 214 is connected to the scan line 101 of the second vertical sub-region 113.
[0044] When the first vertical sub-region 112 includes multiple scan lines 101, the number of first transistors 211 and second transistors 212 can be set to multiple, with multiple first transistors 211 connected in parallel and multiple second transistors 212 connected in parallel. When the second vertical sub-region 113 includes multiple scan lines 101, the number of third transistors 213 and fourth transistors 214 can be set to multiple, with multiple third transistors 213 connected in parallel and multiple fourth transistors 214 connected in parallel.
[0045] The first transistor 211 and the second transistor 212 are turned on alternately, and the average refresh rate of the first vertical sub-region 112 is between the two vertical partitions. The third transistor 213 and the fourth transistor 214 are turned on alternately, and the average refresh rate of the second vertical sub-region 113 is between the two vertical partitions. At the same time, by controlling the turn-on time ratio of the first transistor 211 and the second transistor 212, as well as the turn-on time ratio of the third transistor 213 and the fourth transistor 214, the average refresh rate of the vertical transition region can be controlled.
[0046] In some embodiments, the first control unit 220 includes a first controller 221 and a second controller 222, the control terminals of the first transistor 211 and the second transistor 212 are connected to the first controller 221, and the control terminals of the third transistor 213 and the fourth transistor 214 are connected to the second controller 222.
[0047] The first controller 221 outputs a pulse width modulation (PWM) signal to control the on-time ratio of the first transistor 211 and the second transistor 212. The second controller 222 outputs a pulse width modulation signal to control the on-time ratio of the third transistor 213 and the fourth transistor 214. The on-time ratio of the two transistors is controlled separately by different controllers. The average refresh rate of the first vertical sub-region 112 and the average refresh rate of the second vertical sub-region 113 can be set separately.
[0048] In some embodiments, see Figure 3As shown, the control module 200 also includes a first comparison unit 230, which is connected to the first gate driving unit 310, the second gate driving unit 320, and the first control unit 220. The first comparison unit 230 is used to compare the refresh rates of the first gate driving unit 310 and the second gate driving unit 320. The first control unit 220 controls the first selection unit 210 according to the comparison result, so that the average refresh rate of different areas of the display panel 100 increases or decreases sequentially within a preset time.
[0049] For example, if the refresh rate of the first vertical partition 111 is greater than the refresh rate of the second vertical partition 114, the first control unit 220 controls the first selection unit 210 to work according to the comparison result, so that the average refresh rate of the first vertical sub-region 112 is greater than the average refresh rate of the second vertical sub-region 113. In the column direction, the average refresh rates of the first vertical partition 111, the first vertical sub-region 112, the second vertical sub-region 113 and the second vertical partition 114 decrease sequentially.
[0050] The average refresh rates of the first vertical partition 111, the first vertical sub-partition 112, the second vertical sub-partition 113, and the second vertical partition 114 increase or decrease sequentially, and the refresh rates between the two vertical partitions transition smoothly, which can reduce or eliminate screen flicker and uneven brightness at the junction of the vertical partitions and improve the display effect of the display device.
[0051] In some embodiments, the control module 200 further includes a second comparison unit 240, which is connected to the first gate driving unit 310, the second gate driving unit 320 and the first control unit 220. The second comparison unit 240 is used to compare the difference between the refresh rates of the first gate driving unit 310 and the second gate driving unit 320 with a preset refresh rate.
[0052] When the refresh rate difference is greater than the preset refresh rate, the first control unit 220 controls the first selection unit 210 to switch the scanning signal of the vertical transition area, and the average refresh rate of the first vertical partition 111, the first vertical sub-region 112, the second vertical sub-region 113, and the second vertical partition 114 increases or decreases sequentially. When the refresh rate difference is less than or equal to the preset refresh rate, the first control unit 220 controls the first selection unit 210 not to switch the scanning signal of the vertical transition area, and the refresh rate of the first vertical partition 111 is equal to the refresh rate of either the first vertical partition 111 or the second vertical partition 114, and the refresh rate of the second vertical sub-region 113 is equal to the refresh rate of either the first vertical partition 111 or the second vertical partition 114.
[0053] The first selection unit 210 is controlled according to the relationship between the difference in refresh rates of the first gate driving unit 310 and the second gate driving unit 320 and the preset refresh rate. When the refresh rates of the first gate driving unit 310 and the second gate driving unit 320 are close, the vertical transition area is not enabled, which can reduce the power consumption of the display device.
[0054] Example 2 The difference between Embodiment 2 and Embodiment 1 is that the connection method between the source driver module 400 and the display panel 100 is different.
[0055] See Figure 4 As shown, in this embodiment, the display device includes a source driver module 400, which includes a first source driver unit 410 (SD1) and a second source driver unit 420 (SD2). The display panel 100 includes a first horizontal partition 121, a second horizontal partition 124, and a horizontal transition area. The first horizontal partition 121 and the second horizontal partition 124 are respectively disposed on both sides of the horizontal transition area in the row direction. The data line 102 of the first horizontal partition 121 is connected to the first source driver unit 410, and the data line 102 of the second horizontal partition 124 is connected to the second source driver unit 420.
[0056] The control module 200 includes a second selection unit 250 and a second control unit 260. The second selection unit 250 is connected to the first source drive unit 410, the second source drive unit 420, the data line 102 in the lateral transition region, and the second control unit 260. The second control unit 260 controls the second selection unit 250 to operate, causing the first source drive unit 410 and the second source drive unit 420 to alternately output data signals to the data line 102 in the lateral transition region.
[0057] The display panel 100 is divided into at least two horizontal partitions, and a horizontal transition area is set between the horizontal partitions to reduce or eliminate uneven brightness caused by crosstalk and other reasons.
[0058] In some embodiments, the lateral transition region includes a first lateral sub-region 122. The second selection unit 250 includes a fifth transistor 251 and a sixth transistor 252, which have different channel types. For example, the fifth transistor 251 is an N-channel field-effect transistor, and the sixth transistor 252 is a P-channel field-effect transistor, or vice versa.
[0059] The first terminal of the fifth transistor 251 is connected to the first source driving unit 410, and the second terminal of the fifth transistor 251 is connected to the data line 102 in the first lateral sub-region 122.

The control terminals of both the fifth transistor 251 and the sixth transistor 252 are connected to the second control unit 260. When the first lateral sub-region 122 includes multiple data lines 102, the number of fifth transistors 251 and sixth transistors 252 can be set accordingly, with multiple fifth transistors 251 connected in parallel and multiple sixth transistors 252 connected in parallel.
[0060] The second selection unit 250 includes a fifth transistor 251 and a sixth transistor 252.

When the fifth transistor 251 and the sixth transistor 252 are alternately on, the data signal for the lateral transition region is alternately provided by the two source driving units. At the same time, the brightness of the vertical transition region can be finely adjusted by controlling the on-time ratio of the fifth transistor 251 and the sixth transistor 252 through the second control unit 260.
[0061] In some embodiments, see Figure 5 As shown, the horizontal transition area includes a first horizontal sub-area 122 and a second horizontal sub-area 123.

For example, the fifth transistor 251 can be an N-channel field-effect transistor, and the sixth transistor 252 can be a P-channel field-effect transistor, or vice versa; the seventh transistor 253 can be an N-channel field-effect transistor, and the eighth transistor 254 can be a P-channel field-effect transistor, or vice versa.
[0063] The first terminal of the fifth transistor 251 is connected to the first source driving unit 410, and the second terminal of the fifth transistor 251 is connected to the data line 102 of the first lateral sub-region 122.

The first terminal of the eighth transistor 254 is connected to the second source driving unit 420, and the second terminal of the eighth transistor 254 is connected to the data line 102 of the second lateral sub-region 123.
[0064] When the first horizontal sub-region 122 includes multiple data lines 102, the number of fifth transistors 251 and sixth transistors 252 can be set accordingly, with multiple fifth transistors 251 connected in parallel and multiple sixth transistors 252 connected in parallel. When the second horizontal sub-region 123 includes multiple data lines 102, the number of seventh transistors 253 and eighth transistors 254 can be set accordingly, with multiple seventh transistors 253 connected in parallel and multiple eighth transistors 254 connected in parallel.
[0065] The fifth transistor 251 and the sixth transistor 252 are turned on alternately, and the brightness of the first horizontal sub-region 122 is between the two horizontal sub-regions. The seventh transistor 253 and the eighth transistor 254 are turned on alternately, and the brightness of the second horizontal sub-region 123 is between the two horizontal sub-regions.
[0066] In some embodiments, the second control unit 260 includes a third controller 261 and a fourth controller 262, the control terminals of the fifth transistor 251 and the sixth transistor 252 are connected to the third controller 261, and the control terminals of the seventh transistor 253 and the eighth transistor 254 are connected to the fourth controller 262.
[0067] The third controller 261 outputs a pulse width modulation signal to control the on-time ratio of the fifth transistor 251 and the sixth transistor 252. The fourth controller 262 outputs a pulse width modulation signal to control the on-time ratio of the seventh transistor 253 and the eighth transistor 254. The on-time ratio of the two transistors is controlled separately by different controllers. The average refresh rate of the first horizontal sub-region 122 and the brightness of the second horizontal sub-region 123 can be finely adjusted separately.
