Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device. Background Art

[0002] The timing controller (TCON) is used to convert the video signal obtained from the mainboard into a data signal, and output the data signal to the display panel to drive the display panel.

[0003] The existing display panel is provided with multiple effective sub-pixels and multiple redundant sub-pixels, and the data signal only includes the data to be input to the effective sub-pixels. In order to prevent the data to be input to the effective sub-pixels from being transmitted to the redundant sub-pixels, causing the data signal output to be disordered, it is necessary to insert the redundant data corresponding to the redundant sub-pixels into the data signal. The existing timing controller can only insert redundant data at a fixed position in the data signal sequence. Since the pixel architecture and driving timing of the existing display panel are different, the use of the existing timing controller to output the data signal will cause the data signal of the redundant sub-pixels to be improperly configured or have errors, resulting in poor display problems on the display panel.

The described technical solutions are only used to explain and illustrate the ideas of the present application and should not be regarded as limiting the protection scope of the present application.

[0024] The various embodiments provided in this application are similar, and features in different embodiments may be combined with each other.

[0025] like Figure 1 As shown, an embodiment of the present application provides a display device 100 , including: a display panel 200 and a timing controller 300 , wherein the timing controller 300 and the display panel 200 are electrically connected.

[0026] In an embodiment of the present application, the display panel 200 includes a display area AA and a non-display area NA arranged around the display area AA, the display panel 200 includes a plurality of data lines D and a plurality of scan lines G, and the display panel 200 further includes a gate driver (not shown in the figure) and a source driver 220. The timing controller 300 is electrically connected to the source driver 220 and the gate driver, respectively, and is used to provide driving signals to the source driver 220 and the gate driver. The source driver 220 is electrically connected to the plurality of data lines D, and the gate driver is electrically connected to the plurality of scan lines G.

[0027] In an embodiment of the present application, the display panel 200 further includes a plurality of sub-pixel rows 210, and the sub-pixel rows 210 include a plurality of sub-pixels 211. The sub-pixel 211 includes an effective sub-pixel 211a and a redundant sub-pixel 211b. The plurality of sub-pixel rows 210 include a plurality of sub-pixel 211 groups, and any sub-pixel 211 group includes a red sub-pixel row 210a, a green sub-pixel row 210b, and a blue sub-pixel row 210c arranged along a first direction, the red sub-pixel row 210a includes a plurality of red sub-pixels 211 arranged along a second direction, the green sub-pixel row 210b includes a plurality of green sub-pixels 211 arranged along the second direction, and the blue sub-pixel row 210c includes a plurality of blue sub-pixels 211 arranged along the second direction, the first direction and the second direction intersect, and at least part of the sub-pixel rows 210 include a redundant sub-pixel 211b. The plurality of effective sub-pixels 211a in the sub-pixel row 210 are arranged adjacent to each other. The redundant sub-pixel 211 b is disposed on one side of the effective sub-pixel 211 a close to the non-display area or on two opposite sides of the effective sub-pixel 211 a close to the non-display area.

[0028] like Figure 2 As shown, the display panel 200 includes a plurality of sub-pixel rows 210 , the sub-pixel rows 210 include a plurality of sub-pixels 211 , and the sub-pixels 211 include effective sub-pixels 211 a and redundant sub-pixels 211 b .

[0029] like Figure 3 As shown, the timing controller 300 includes: an acquisition unit 110, a storage unit 120 and a processing unit 130. The acquisition unit 110 is electrically connected to the storage unit 120 and the processing unit 130. The storage unit 120 is electrically connected to the processing unit 130. The processing unit 130 is electrically connected to the display panel.

[0030] like Figure 2 and Figure 3 As shown, the acquisition unit 110 is used to acquire the initial image data of the picture to be displayed. The initial image data includes a plurality of initial data packets, the initial data packets include a plurality of valid data bits, the sequence number of the valid data bits in the initial data packets corresponds to the position of the valid sub-pixel 211a in the sub-pixel row 210, and the number of valid data bits is equal to the number of valid sub-pixels 211a. For example, the initial data packet includes N valid data bits, and correspondingly, a sub-pixel row 210 includes N valid sub-pixels 211a, wherein the value of the third valid data bit is "1", then the data signal corresponding to the valid data bit "1" is output to the third valid sub-pixel 211a in the sub-pixel row 210. N is a positive integer greater than 1.

[0031] In the embodiment of the present application, the values ​​of the multiple valid data bits are equal. For example, the initial data packet includes 8 valid data bits, and the value of each valid data bit is "1", that is, the initial data packet is "11111111", and correspondingly, a sub-pixel row 210 includes 8 valid sub-pixels 211a, and the data signal corresponding to the valid data bit "1" is output to each valid sub-pixel 211a in the sub-pixel row 210.

[0032] In the embodiment of the present application, the storage unit 120 is used to store initial image data, where the initial image data includes first identification data to be input to the effective sub-pixel.

[0033] In an embodiment of the present application, the first identification data includes the position and number of valid data bits. The redundant sub-pixel 211b is located on the side of the valid sub-pixel 211a close to the edge of the display panel. For example, the sub-pixel row 210 includes K sub-pixels 211, the 1st to the Mth sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211b, the M+1st to the Pth sub-pixels 211 in the sub-pixel row 210 are valid sub-pixels 211a, and the P+1st to the Kth sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211b. K is greater than P, P is greater than M, and M is a positive integer greater than or equal to 1, P is a positive integer greater than or equal to 4, and K is a positive integer greater than or equal to 4. When M is equal to 1, the first sub-pixel 211 of the sub-pixel row 210 is a redundant sub-pixel 211 b , and the P+1th to Kth sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211 b .

[0034] Alternatively, the sub-pixel row 210 includes K sub-pixels 211, the 1st to Mth sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211b, and the M+1th to Kth sub-pixels 211 in the sub-pixel row 210 are valid sub-pixels 211a. Wherein, K is greater than M, and M is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. When M is equal to 1, that is, only the 1st sub-pixel 211 in the sub-pixel row 210 is a redundant sub-pixel 211b.

[0035] Alternatively, the sub-pixel row 210 includes K sub-pixels 211, the 1st to Mth sub-pixels 211 in the sub-pixel row 210 are valid sub-pixels 211a, and the M+1th to Kth sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211b. K is greater than M, M is a positive integer greater than 1, and K is a positive integer greater than or equal to 4.

[0036] That is, the subpixel row 210 includes a plurality of adjacently arranged effective subpixels 211a, and a plurality of redundant subpixels 211b are located on one side of the plurality of effective subpixels 211a close to the edge of the display panel, or the plurality of redundant subpixels 211b are located on two opposite sides of the plurality of effective subpixels 211a close to the edge of the display panel. Wherein, when the plurality of redundant subpixels 211b are located on two opposite sides of the plurality of effective subpixels 211a close to the edge of the display panel, the number of redundant subpixels 211b located on one side of the effective subpixel 211a is not equal to the number of redundant subpixels 211b located on the other side of the effective subpixel 211a. For example, the first subpixel 211 in the subpixel row 210 is a redundant subpixel 211b, the second to the 1000th subpixels 211 are effective subpixels 211a, and the 1001st to the 1018th subpixels 211 are redundant subpixels 211b. Alternatively, the first sub-pixel 211 in the sub-pixel row 210 is a redundant sub-pixel 211b, and the second to 1018th sub-pixels 211 are effective sub-pixels 211a. Alternatively, the first to 1000th sub-pixels 211 in the sub-pixel row 210 are effective sub-pixels 211a, and the 1001st to 1018th sub-pixels 211 are redundant sub-pixels 211b. The number of redundant sub-pixels 211b can be adjusted according to the architecture of the display panel.

[0037] Alternatively, when the plurality of redundant sub-pixels 211b are located on opposite sides of the plurality of effective sub-pixels 211a close to the edge of the display panel, the number of redundant sub-pixels 211b located on one side of the effective sub-pixel 211a is equal to the number of redundant sub-pixels 211b located on the other side of the effective sub-pixel 211a. For example, the first to second sub-pixels 211 in the sub-pixel row 210 are redundant sub-pixels 211b, the third to 1016th sub-pixels 211 are effective sub-pixels 211a, and the 1017th to 1018th sub-pixels 211 are redundant sub-pixels 211b.

[0038] In an embodiment of the present application, a plurality of sub-pixel rows 210 include a plurality of sub-pixel groups 211, any sub-pixel 211 group includes a red sub-pixel row 210a, a green sub-pixel row 210b, and a blue sub-pixel row 210c arranged along a first direction, the red sub-pixel row 210a includes a plurality of red sub-pixels 211 arranged along a second direction, the green sub-pixel row 210b includes a plurality of green sub-pixels 211 arranged along the second direction, the blue sub-pixel row 210c includes a plurality of blue sub-pixels 211 arranged along the second direction, and the first direction and the second direction intersect.

[0039] In an embodiment of the present application, the number of initial data packets is less than or equal to the number of sub-pixel rows 210. Specifically, the number of initial data packets is equal to the number of sub-pixel rows 210 that the display panel needs to drive to display the picture to be displayed. For example, if the picture to be displayed is a red picture, a green picture, or a blue picture, the number of sub-pixel rows 210 that the display panel needs to drive to display the red picture, the green picture, or the blue picture is one third of the number of sub-pixel rows 210 in the display panel.

[0040] Specifically, the display panel only needs to drive multiple red sub-pixel rows 210a to display a red image, and the number of initial data packets is equal to the number of red sub-pixel rows 210a in the display panel. The display panel only needs to drive multiple green sub-pixel rows 210b to display a green image, and the number of initial data packets is equal to the number of green sub-pixel rows 210b in the display panel. The display panel only needs to drive multiple blue sub-pixel rows 210c to display a blue image, and the number of initial data packets is equal to the number of blue sub-pixel rows 210c in the display panel.

[0041] Alternatively, the display panel needs to drive all sub-pixel rows 210 in the display panel to display the image to be displayed, and the number of initial data packets is equal to the number of sub-pixel rows 210 in the display panel.

[0042] like Figure 4 As shown, the sub-pixel row 210 includes K sub-pixels 211. When the image to be displayed is a red image, the 1st to Mth sub-pixels 211 in any red sub-pixel row 210a are valid sub-pixels 211a, and the M+1th to Kth sub-pixels 211 in the red sub-pixel row 210a are redundant sub-pixels 211b. K is greater than M, and M is a positive integer greater than 1, and K is a positive integer greater than or equal to 4. For example, M is equal to 5, and K is equal to 7.

[0043] And the 1st to Nth sub-pixels 211 of another red sub-pixel row 210a are redundant sub-pixels 211b, the N+1th to Pth sub-pixels 211 in the red sub-pixel row 210a are valid sub-pixels 211a, and the P+1th to Kth sub-pixels 211 in the red sub-pixel row 210a are redundant sub-pixels 211b. Wherein, K is greater than P, P is greater than N, and N is a positive integer greater than or equal to 1, P is a positive integer greater than or equal to 4, and K is a positive integer greater than or equal to 4. For example, N is equal to 2, P is equal to 7, and K is equal to 9.

[0044] like Figure 5As shown, the sub-pixel row 210 includes K sub-pixels 211. When the image to be displayed is a green image, the 1st to Sth sub-pixels 211 in any green sub-pixel row 210b are redundant sub-pixels 211b, and the S+1st to Kth sub-pixels 211 in the green sub-pixel row 210b are valid sub-pixels 211a. K is greater than S, and S is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, S is equal to 2, and K is equal to 7.

[0045] And the 1st to Qth sub-pixels 211 of another green sub-pixel row 210b are effective sub-pixels 211a, and the Q+1th to Kth sub-pixels 211 in the green sub-pixel row 210b are redundant sub-pixels 211b. Wherein, K is greater than Q, and Q is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, Q is equal to 5, and K is equal to 7.

[0046] like Figure 6 As shown, the sub-pixel row 210 includes K sub-pixels 211. When the image to be displayed is a blue image, the 1st to Qth sub-pixels 211 in any blue sub-pixel row 210c are valid sub-pixels 211a, and the Q+1st to Kth sub-pixels 211 in the blue sub-pixel row 210c are redundant sub-pixels 211b. K is greater than Q, and Q is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, Q is equal to 5, and K is equal to 7.

[0047] And the 1st to Sth sub-pixels 211 in another blue sub-pixel row 210c are redundant sub-pixels 211b, and the S+1th to Kth sub-pixels 211 in the blue sub-pixel row 210c are valid sub-pixels 211a. Wherein, K is greater than S, and S is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, S is equal to 2, and K is equal to 7.

[0048] In an embodiment of the present application, the processing unit 130 is used to obtain second identification data to be input into the redundant sub-pixel based on the first identification data, and to adjust the initial image data to target image data based on the first identification data and the second identification data, and to output the target image data.

[0049] In an embodiment of the present application, the target image data includes multiple target data packets, each target data packet includes multiple valid data bits, and at least some of the target data packets also include redundant data bits, the sequence numbers of the redundant data bits in the target data packets correspond to the positions of the redundant sub-pixels 211b in the sub-pixel row 210, and the number of redundant data bits is equal to the number of redundant sub-pixels 211b.

[0050] In an embodiment of the present application, the second identification data includes the position and number of redundant data bits. Specifically, the processing unit 130 is used to insert the redundant data bits corresponding to the redundant sub-pixel 211b into the initial data packet according to the position and number of valid data bits in the sub-pixel row 210 and the position and number of redundant data bits to generate a target data packet.

[0051] In an embodiment of the present application, the sequence numbers of the redundant data bits in at least some of the target data packets are different, and / or the number of the redundant data bits in at least some of the target data packets is different. Specifically, the value of the valid data bit is "1" and the value of the redundant data bit is "0".

[0052] In an embodiment of the present application, the number of target data packets is the same as the number of initial data packets.

[0053] As a specific implementation, the sub-pixel row 210 includes K sub-pixels 211. When the image to be displayed is a red image, if the 1st to Mth sub-pixels 211 of any red sub-pixel row 210a are valid sub-pixels 211a, the M+1th to Kth sub-pixels 211 in the red sub-pixel row 210a are redundant sub-pixels 211b. Wherein, K is greater than M, and M is a positive integer greater than 1, and K is a positive integer greater than or equal to 4. For example, M is equal to 5, and K is equal to 7. Then the initial data packet corresponding to the red sub-pixel row 210a is "11111", and the target data packet corresponding to the red sub-pixel row 210a is "1111100", that is, two redundant data bits are inserted at the end of the initial data packet, so as to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the red sub-pixel row 210a when driving the display panel.

[0054] Specifically, if the 1st to Nth sub-pixels 211 of another red sub-pixel row 210a are redundant sub-pixels 211b, the N+1th to Pth sub-pixels 211 in the red sub-pixel row 210a are valid sub-pixels 211a, and the P+1th to Kth sub-pixels 211 in the red sub-pixel row 210a are redundant sub-pixels 211b. Wherein, K is greater than P, P is greater than N, and N is a positive integer greater than or equal to 1, P is a positive integer greater than or equal to 4, and K is a positive integer greater than or equal to 4. For example, N is equal to 2, P is equal to 7, and K is equal to 9. The initial data packet corresponding to the red sub-pixel row 210a is "11111", and the target data packet corresponding to the red sub-pixel row 210a is "001111100", that is, two redundant data bits are inserted at the beginning and the end of the initial data packet, so as to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the red sub-pixel row 210a when driving the display panel.

Wherein, K is greater than S, and S is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, S is equal to 2, and K is equal to 7. Then the initial data packet corresponding to the green sub-pixel row 210b is "11111", and the target data packet corresponding to the red sub-pixel row 210a is "0011111", that is, two redundant data bits are inserted at the beginning of the initial data packet, so as to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the red sub-pixel row 210a when driving the display panel.

[0056] Specifically, if the 1st to Qth sub-pixels 211 of another green sub-pixel row 210b are valid sub-pixels 211a, the Q+1th to Kth sub-pixels 211 in the green sub-pixel row 210b are redundant sub-pixels 211b. Wherein, K is greater than Q, and Q is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, Q is equal to 5, and K is equal to 7. Then the initial data packet corresponding to the green sub-pixel row 210b is "11111", and the target data packet corresponding to the green sub-pixel row 210b is "1111100", that is, two redundant data bits are inserted at the end of the initial data packet, so as to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the green sub-pixel row 210b when driving the display panel.

[0057] As a specific implementation, the sub-pixel row 210 includes K sub-pixels 211. When the image to be displayed is a blue image, if the 1st to Qth sub-pixels 211 of any blue sub-pixel row 210c are valid sub-pixels 211a, the Q+1st to Kth sub-pixels 211 in the blue sub-pixel row 210c are redundant sub-pixels 211b. Wherein, K is greater than Q, and Q is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, Q is equal to 5, and K is equal to 7. Then the initial data packet corresponding to the blue sub-pixel row 210c is "11111", and the target data packet corresponding to the blue sub-pixel row 210c is "1111100", that is, two redundant data bits are inserted at the end of the initial data packet, so as to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the green sub-pixel row 210b when driving the display panel.

[0058] Specifically, if the 1st to Sth sub-pixels 211 in another blue sub-pixel row 210c are redundant sub-pixels 211b, the S+1th to Kth sub-pixels 211 in the blue sub-pixel row 210c are valid sub-pixels 211a. Wherein, K is greater than S, and S is a positive integer greater than or equal to 1, and K is a positive integer greater than or equal to 3. For example, S is equal to 2, and K is equal to 7. Then the initial data packet corresponding to the blue sub-pixel row 210c is "11111", and the target data packet corresponding to the blue sub-pixel row 210c is "0011111", that is, two redundant data bits are inserted at the beginning of the initial data packet to input the data signal corresponding to the redundant data bit "0" to the redundant sub-pixel 211b in the red sub-pixel row 210a when driving the display panel.

[0059] like Figure 7 As shown, the timing controller 300 also includes a judgment unit 140. The judgment unit 140 is used to judge whether the initial image data of at least two consecutive frames to be displayed are the same. If they are the same, the judgment unit 140 is used to output the initial image data of one frame to be displayed to the storage unit 120 and issue a continuous output instruction to the processing unit 130. For example, the judgment unit 140 is used to obtain the initial image data of two consecutive frames to be displayed, and compare the initial image data of the two consecutive frames to be displayed to determine whether the initial image data of the two consecutive frames to be displayed are the same. If the initial image data of the two consecutive frames to be displayed are the same, the judgment unit 140 is used to output the initial image data of any frame of the two consecutive frames to be displayed to the storage unit 120, so as to store the initial image data through the storage unit 120. At the same time, the judgment unit 140 issues a continuous output instruction to the processing unit 130. The continuous output instruction is an instruction to continuously drive the display panel to display two frames of display images according to the acquired target image data.

[0060] In the embodiment of the present application, if the initial image data corresponding to at least two consecutive frames of the to-be-displayed pictures are different, the determination unit 140 is configured to output the initial image data of at least one frame of the to-be-displayed picture to the storage unit 120 .

[0061] For example, the judgment unit 140 is also used to obtain the initial image data of two consecutive frames to be displayed, and compare the initial image data of the two consecutive frames to be displayed to determine whether the initial image data of the two consecutive frames to be displayed are the same. If the initial image data of the two consecutive frames to be displayed are not the same, the judgment unit 140 is used to output the initial image data of the first frame to be displayed in the two consecutive frames to be displayed to the storage unit 120, so as to store and identify the initial image data through the storage unit 120. Alternatively, if the initial image data of the two consecutive frames to be displayed are not the same, the judgment unit 140 is used to output the initial image data corresponding to the two consecutive frames to be displayed to the storage unit 120, so as to store the initial image data through the storage unit 120.
