Description

Technical Field

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

[0002] With the development of display technology, people have higher and higher requirements on the resolution of display devices. For high-resolution products, a large amount of data transmission is required, which leads to a decrease in the refresh rate of electronic products.

[0003] In the related art, the display device usually adopts the method of scanning the attention area and the non-attention area separately to reduce the amount of data transmission. Specifically, the display device obtains the position of the attention area through the human eye gaze coordinates. During the scanning process, the sub-pixel units in the attention area are scanned line by line, and the sub-pixel units in the non-attention area are scanned simultaneously in multiple lines. In this way, the amount of data transmission can be reduced while ensuring the display effect.

[0004] However, the display device generally writes data signals in a row-by-row scanning manner, and therefore, the sub-pixel units located on both sides of the viewing area cannot be scanned in multiple rows simultaneously.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0060] This exemplary embodiment provides a display device such as Figure 1 , 2 , 3, Figure 1 This is a schematic diagram of the working principle of an exemplary embodiment of the display device disclosed in the present invention. Figure 2 is a pixel structure distribution diagram in an exemplary embodiment of the display device disclosed in the present invention, Figure 3 This is a functional block diagram of an exemplary embodiment of the display device of the present disclosure. The display device may include: a plurality of pixel island groups 1, a plurality of lenses 2, a positioning module 6, and a gate drive chip 5. The plurality of pixel island groups 1 are arranged in an array, and each of the pixel island groups 1 may include a plurality of pixel islands 11. Each of the pixel islands 11 may include a plurality of sub-pixel units P of the same color distributed in an array, and different pixel islands 11 may be scanned in different scanning modes; the lens 2 may be arranged in a one-to-one correspondence with the pixel island 11, and the lens 2 may be used to image the corresponding pixel island 11 to a preset virtual image plane A. Specifically, the lens 2 may transmit the light emitted by the pixel island 11 to the human eye 0, and the human eye 0 may see the image formed by the pixel island 11 on the preset virtual image plane A. The positioning module 6 can determine the gaze area 31 and the non-attention area according to the human eye gaze coordinates 41, wherein 25 pixel island groups can be arranged in the gaze area 31; the gate drive chip 5 is used to provide gate drive signals to the sub-pixel units in the gaze area 31 row by row during the scanning phase of the sub-pixel units in the gaze area 31, and is used to provide gate drive signals to adjacent multiple rows of sub-pixel units in the non-attention area at the same time during the scanning phase of the sub-pixel units in the non-attention area.

[0061] In this exemplary embodiment, different pixel islands 11 can be scanned in different scanning modes, that is, each pixel island can independently select multiple rows to scan simultaneously or scan row by row. For example, in two pixel islands located in the same row, one pixel island can scan the sub-pixel units therein row by row, and the other pixel island can scan the sub-pixel units therein in multiple rows at the same time. It should be understood that scanning a sub-pixel unit can be understood as writing a data signal to the sub-pixel unit under the action of a gate drive signal.

[0062] In this exemplary embodiment, the display device divides the viewing area and the non-viewing area outside the viewing area into basic units using pixel island groups, and different pixel islands 11 can be scanned in different scanning modes, so that the display device can scan only the sub-pixel units in the viewing area row by row and scan multiple rows of sub-pixel units in the non-viewing area simultaneously.

[0063] In this exemplary embodiment, the positioning module 6 determines the gaze area 31 according to the gaze coordinates 41 of the human eye, which may include: the positioning module 6 determines the gaze coordinates 41 according to the line of sight of the human eye, the gaze coordinates 41 may be located on a pixel island group, and the gaze coordinates 41 may be located at the center of the gaze area 31. When the gaze area is located at a corner of the display device, the gaze coordinates may also be located at a non-central position of the gaze area. For example, Figure 2 As shown, when the gaze coordinate is located at the position of the dotted frame 42, the gaze area is located at the position of the dotted frame 32. If the gaze coordinate is located at any position in the dotted frame 32, the gaze area corresponding to the gaze coordinate is located at the position of the dotted frame 32.

[0064] It should be understood that in other exemplary embodiments, multiple rows of sub-pixel units in the attention area may be scanned simultaneously, wherein the number of rows of sub-pixel units scanned simultaneously in the attention area may be less than the number of rows of sub-pixel units scanned simultaneously in the non-attention area. In other exemplary embodiments, the attention area 31 may also include other numbers of pixel island groups, for example, the attention area 31 may include 1 pixel island group, 4 pixel island groups, and so on.

[0065] In this exemplary embodiment, when the display device forms a light-emitting material layer on the pixel definition layer, the opening size of the mask can be equal to the size of the pixel island, and the opening of the mask can be directly opposite to the pixel island. Thus, the light-emitting material layer on each pixel island can be an integral structure. This setting can increase the aperture ratio of the display device, thereby improving the brightness of the display device.

[0066] In this exemplary embodiment, Figure 4 , which is a schematic diagram of the structure of another exemplary embodiment of the display device of the present disclosure. One way to achieve that different pixel islands can be scanned in different scanning modes may be that the gate drive chip 5 may include: a plurality of sub-drive chips 51, the sub-drive chips 51 are arranged in a one-to-one correspondence with the pixel islands 11, and each of the sub-drive chips 51 is used to independently provide a gate drive signal to the pixel island 11 corresponding thereto. For example, one sub-drive chip 51 can provide a gate drive signal to the sub-pixel units in the pixel island 11 row by row, and another sub-drive chip 51 can provide a gate drive signal to the sub-pixel units in the pixel island 11 in multiple rows at the same time.

[0067] In this exemplary embodiment, Figure 5As shown, it is a schematic diagram of the structure of another exemplary embodiment of the display device disclosed in the present invention. One way to achieve that different pixel islands can be scanned in different scanning modes may also be that the display device further includes: a plurality of switch components 7, the switch components 7 are arranged in a one-to-one correspondence with the pixel islands 11, the switch components 7 may include a plurality of switch units 71, the number of the switch units 71 may be the same as the number of columns of sub-pixel units in the pixel island 11, and the sub-pixel units in the same column in the pixel island 11 may be connected to the data line Data through the switch units 71, wherein the data line Data is connected to the source driving circuit, and is used to transmit the data signal output by the source driving circuit to the sub-pixel unit. The switch unit 71 may be used to respond to a control signal to connect the data line Data and the sub-pixel unit P in the same column in the pixel island 11. As shown in FIG. Figure 5 As shown, the sub-pixel units in the same row in the display device can be connected to a gate line Gate1, Gate2, etc., and the gate line can be used to transmit the gate drive signal provided by the gate drive chip to the sub-pixel unit. The display device can realize different scanning modes of different pixel islands by controlling the switch component 7. For example, Figure 5 As shown, when the display device needs to scan line by line Figure 5 When the display device needs to scan the pixel island on the upper left, all the switch units 71 in the switch assembly 7 corresponding to the pixel island on the upper left can be turned on, and gate drive signals are provided to the gate lines Gate1 and Gate2 row by row; when the display device needs to scan the pixel island on the upper right in multiple rows at the same time, all the switch units 71 in the switch assembly 7 corresponding to the pixel island on the upper right can be turned on, and gate drive signals are provided to the gate lines Gate1 and Gate2 at the same time. It should be noted that this exemplary embodiment only takes the pixel island including 2*2 sub-pixel units as an example for description, and in other exemplary embodiments, the pixel island may also include other numbers of sub-pixel units.

[0068] In this exemplary embodiment, in one frame scan, the gate driver chip can provide gate drive signals to the sub-pixel units connected thereto in any order. For example, in one frame scan, the gate driver chip can first provide gate drive signals to the sub-pixel units in the attention zone, so that the sub-pixel units located in the attention zone are scanned first. This setting can enable the display device to adjust the scanning mode in the attention zone in a timely manner when the position of the attention zone changes, thereby improving the display effect.

[0069] In this exemplary embodiment, Figure 3As shown, the display device may further include a source driving circuit 8, which may be used to output a data signal according to a pixel value; wherein the source driving circuit 8 is used to provide a data signal to a column of sub-pixel units in the viewing area according to a pixel value during the scanning phase of the sub-pixel units in the viewing area, and is used to provide the same data signal to multiple columns of sub-pixel units in the non-viewing area according to a pixel value during the scanning phase of the sub-pixel units in the non-viewing area. That is, in the scanning phase of the sub-pixel units in the viewing area, the data signals received by sub-pixel units in different columns may correspond to a pixel value respectively, and the multiple columns of sub-pixel units may display different or the same grayscale. In the scanning phase of the sub-pixel units in the non-viewing area, the data signals received by sub-pixel units in different columns can only correspond to the same pixel value, and the multiple columns of sub-pixel units can only display the same grayscale. This setting only reduces the amount of pixel value data in the non-viewing area, thereby reducing the amount of data transmission of the display device under the premise of ensuring a certain display effect, thereby reducing the power consumption of the display device.

[0070] In this exemplary embodiment, Figure 6 As shown, it is a schematic diagram of the structure of the pixel island group in an exemplary embodiment of the display device of the present disclosure. The pixel island group 1 may include: an R pixel island 11R, a B pixel island 11B, a first G pixel island 11G1, and a second G pixel island 11G2. The R pixel island 11R, the B pixel island 11B, the first G pixel island 11G1, and the second G pixel island 11G2 may respectively form the above-mentioned pixel islands. The R pixel island 11R may include 8 rows and 8 columns of R sub-pixel units R, wherein the R sub-pixel unit in the Xth row and Yth column is located in the same column as the R sub-pixel unit in the X+2th row and Yth column, and the R sub-pixel unit in the Xth row and Yth column is located in the same row as the R sub-pixel unit in the Xth row and Y+2 column. That is, the R sub-pixel units in adjacent rows are staggered by one sub-pixel unit position in the row direction, and the R sub-pixel units in adjacent columns are staggered by one sub-pixel unit position in the column direction.

[0085] In this exemplary embodiment, acquiring the pixel value of the target sub-pixel unit according to the pixel value of the key sub-pixel and the pixel value of the related sub-pixel may include:

[0086] Obtaining a weight of the key sub-pixel to the pixel value of the target sub-pixel unit and a weight of the relevant sub-pixel to the pixel value of the target sub-pixel unit according to the pixel value of the key sub-pixel and the pixel value of the relevant sub-pixel;

[0087] Obtaining a pixel value of a target sub-pixel unit according to the pixel value of the key sub-pixel, the pixel value of the related sub-pixel, and the weight corresponding to the key sub-pixel and the weight corresponding to the related sub-pixel;

The preset judgment rule can be to compare the average value obtained by the above calculation with a threshold, and obtain a group of corresponding weight values ​​according to the size relationship between the above average value and the threshold. The group of weight values ​​may include the weight of the key sub-pixel to the pixel value of the target sub-pixel unit, and the weight of the related sub-pixel to the pixel value of the target sub-pixel unit.

[0091] In this exemplary embodiment, the related sub-pixel may be multiple, and the key sub-pixel and the multiple related sub-pixels may be arranged in an array structure.
