Description

Technical Field

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

[0002] With the continuous development of display technology, three-dimensional (3D) display technology has attracted more and more attention. Three-dimensional display technology can make the display image three-dimensional and realistic. Its principle is: use the left and right eyes of a person to receive the left eye image and the right eye image with a certain parallax respectively. When the two parallax images are received by the left and right eyes of a person respectively, the image information is superimposed and fused through the brain to construct a 3D visual display effect.

[0003] In order to achieve compatibility between ultra-multi-viewpoint 3D display and light field display, the traditional sub-pixel is made into a pixel island structure, each pixel island contains multiple sub-pixels. When the display information of multiple sub-pixels is different, light field 3D display can be achieved; when multiple sub-pixels are grouped and each group of sub-pixels is combined for display, ultra-multi-viewpoint 3D display can be achieved. However, in the prior art, each group of sub-pixels can only be set to display the same information, that is, each group of sub-pixels in the pixel island can only be fixedly combined. When the position of the human eye changes, the combined display sub-pixels cannot change accordingly. Summary of the invention

Among them, the control end of the first first selection switch T11 in each data selection circuit 8 is coupled to MU1, the control end of the first second selection switch T21 in each data selection circuit 8 is coupled to MU2, the control end of the second first selection switch T12 in each data selection circuit 8 is coupled to MU3, the control end of the second second selection switch T22 in each data selection circuit 8 is coupled to MU4, the control end of the third first selection switch T13 in each data selection circuit 8 is coupled to MU5, the control end of the third second selection switch T23 in each data selection circuit 8 is coupled to MU6, the control end of the fourth first selection switch T14 in each data selection circuit 8 is coupled to MU7, and the control end of the fourth second selection switch T24 in each data selection circuit 8 is coupled to MU8.

[0122] In specific implementation, Figure 1 As shown, in each data selection circuit 8, the output end of the first first selection switch T11 and the output end of the first second selection switch T21 are coupled to the same data line 4, the output end of the second first selection switch T12 and the output end of the second second selection switch T22 are coupled to the same data line 4, the output end of the third first selection switch T13 and the output end of the third second selection switch T23 are coupled to the same data line 4, and the output end of the fourth first selection switch T14 and the output end of the fourth second selection switch T24 are coupled to the same data line 4.

[0123] In specific implementation, Figure 1As shown, in each data selection circuit 8, the input ends of the first selection switches T11, T12, T13, and T14 are coupled to the same data input line D, the input ends of the second selection switches T21, T22, T23, and T24 are coupled to the same data input line D, and the input ends of the first selection switches T11, T12, T13, and T14 and the input ends of the second selection switches T21, T22, T23, and T24 are coupled to different data input lines D. For example, Figure 1 In the first data selection circuit 8 from left to right, the input ends of the first selection switches T11, T12, T13, and T14 are coupled to D1, and the input ends of the second selection switches T21, T22, T23, and T24 are coupled to D0. In the second data selection circuit 8, the input ends of the first selection switches T11, T12, T13, and T14 are coupled to D2, and the input ends of the second selection switches T21, T22, T23, and T24 are coupled to D1. In the third data selection circuit 8, the input ends of the first selection switches T11, T12, T13, and T14 are coupled to D3, and the input ends of the second selection switches T21, T22, T23, and T24 are coupled to D2. And so on, which will not be repeated here.

[0124] It should be noted that, in specific implementation, the viewpoint needs to correspond to the red sub-pixel, the blue sub-pixel and the green sub-pixel. Next, taking a sub-pixel row of a pixel island including 16 sub-pixels as an example, the correspondence between sub-pixels and viewpoints is illustrated.

[0125] When a pixel island corresponds to 16 viewpoints, each sub-pixel in the same row of each sub-pixel group in the pixel island needs to display different display information. In some display situations, for example, Figure 2 As shown, the i-th viewpoint Pi corresponds to Ri, Gi, and Bi in the first pixel island 22, where i is a positive integer less than or equal to 16. Figure 1 Taking the coupling of the first four data selection circuits arranged from left to right in the figure as an example, in a specific implementation, the first selection switches T11, T12, T13, T14 in the data selection circuit can be controlled to be turned on in sequence through the data selection control signal lines MU1, MU3, MU5, and MU7, and the data signals corresponding to the viewpoints Pi~P4i can be provided in sequence through Di. At the same time, the second selection switches T21, T22, T23, and T24 in the data selection circuit can be controlled to be turned off through the data selection control signal lines MU2, MU4, MU6, and MU8.

[0126] When a pixel island corresponds to 4 viewpoints, the four sub-pixels in each row of the pixel island are combined for display. Figure 3As shown, the i-th viewpoint Pi corresponds to R4i-3~R4i, G4i-3~G4i, B4i-3~B4i in the first pixel island 22, where i is a positive integer less than or equal to 4. In a specific implementation, the first selection switches T11, T12, T13, and T14 in the data selection circuit can be controlled to be turned on at the same time through the data selection control signal lines MU1, MU3, MU5, and MU7, and the data signals corresponding to the viewpoint Pi are sequentially provided through Di, and the second selection switches T21, T22, T23, and T24 in the data selection circuit can be controlled to be turned off through the data selection control signal lines MU2, MU4, MU6, and MU8.

[0127] In some display situations, for example, when the user's eyes move, the sub-pixel corresponding to the viewpoint moves to the Figure 3 When the right side is shifted, when one sub-pixel is shifted, the sub-pixels corresponding to the user's gaze area viewpoint can be as follows: Figure 4As shown, the first viewpoint P1 corresponds to R2-R5, G2-G5, B2-B5 in the first pixel island 22, the second viewpoint P2 corresponds to R6-R9, G6-G9, B6-B9 in the first pixel island 22, the third viewpoint P3 corresponds to R10-R13, G10-G13, B10-B13 in the first pixel island 22, and the fourth viewpoint P4 corresponds to R14-R16, G14-G16, B14-B16 in the first pixel island 22 and R1, G1, B1 in the second pixel island 23. In a specific implementation, each sub-pixel in a sub-pixel group can be implemented by only using each first selection switch in the data selection circuit to input a different data signal. For example, D0 sequentially inputs data signals d4 and d1, D1 sequentially inputs data signals d1 and d2, D2 sequentially inputs data signals d2 and d3, D3 sequentially inputs data signals d3 and d4, and D4 sequentially inputs data signals d4 and d1. Provide a first data selection control signal to MU1, and then provide a first data selection control signal to MU3, MU5, and MU7 at the same time to control T11 in each data selection circuit to turn on first, and then T12, T13, and T14 to turn on at the same time. At the same time, provide a second data selection control signal to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23, and T24 in each data selection circuit to turn off. Alternatively, the first selection switch and the second selection switch in the data selection circuit can also be used to realize that each sub-pixel in a sub-pixel group inputs different data signals. Specifically, D0 inputs a d4 data signal, D1 inputs a d1 data signal, D2 inputs a d2 data signal, D3 inputs a d3 data signal, and D4 inputs a d4 data signal. A first data selection control signal is provided to MU2, MU3, MU5, and MU7 simultaneously to control T21, T12, T13, and T14 in each data selection circuit to be turned on simultaneously. A second data selection control signal is provided to MU1, MU4, MU6, and MU8 simultaneously to control T11, T22, T23, and T24 in each data selection circuit to be turned off.

[0128] In some display situations, for example, when the user's eyes continue to move, the sub-pixel corresponding to the viewpoint moves to the Figure 4 When the right side is shifted by one sub-pixel again, the sub-pixels corresponding to the user's gaze area viewpoint can be as follows: Figure 5As shown, the first viewpoint P1 corresponds to R3-R6, G3-G6, B3-B6 in the first pixel island 22, the second viewpoint P2 corresponds to R7-R10, G7-G10, B7-B10 in the first pixel island 22, the third viewpoint P3 corresponds to R11-R14, G11-G14, B11-B14 in the first pixel island 22, the fourth viewpoint P4 corresponds to R15-R16, G15-G16, B15-B16 in the first pixel island 22 and R1, R2, G1, G2, B1, B2 in the second pixel island 23. In a specific implementation, each sub-pixel in a sub-pixel group can be implemented by only using each first selection switch in the data selection circuit to input a different data signal. D0 sequentially inputs data signals d4 and d1, D1 sequentially inputs data signals d1 and d2, D2 sequentially inputs data signals d2 and d3, D3 sequentially inputs data signals d3 and d4, and D4 sequentially inputs data signals d4 and d1. At the same time, a first data selection control signal is provided to MU1 and MU3, and then a first data selection control signal is provided to MU5 and MU7 simultaneously to control T11 and T12 in each data selection circuit to be turned on simultaneously first, and then T13 and T14 are turned on simultaneously. At the same time, a second data selection control signal is provided to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23, and T24 in each data selection circuit to be turned off. Alternatively, the first selection switch and the second selection switch in the data selection circuit can also be used to realize that each sub-pixel in a sub-pixel group inputs different data signals. Specifically, D0 inputs a d4 data signal, D1 inputs a d1 data signal, D2 inputs a d2 data signal, D3 inputs a d3 data signal, and D4 inputs a d4 data signal. A first data selection control signal is provided to MU2, MU4, MU5, and MU7 simultaneously to control T21, T22, T13, and T14 in each data selection circuit to be turned on simultaneously. A second data selection control signal is provided to MU1, MU3, MU6, and MU8 simultaneously to control T11, T12, T23, and T24 in each data selection circuit to be turned off.

[0129] In a specific implementation, the display panel may be a rigid display panel or a flexible display panel, that is, the display panel is bendable and foldable.

[0130] In some embodiments, the display panel provided by the embodiments of the present disclosure is a liquid crystal display panel, which can be a twisted nematic (TN) type, a vertical alignment (VA) type, an in-plane switching (IPS) type, or an advanced super dimension switch (ADS) type liquid crystal display panel.

[0135] The cylindrical lens structure 25 is located at the light-emitting side of the display panel; the cylindrical lens structure includes a plurality of cylindrical lenses arranged in an array.

[0136] In some embodiments, Figure 6 As shown, the display device also includes:

[0137] A light-transmitting spacer layer 26 is located between the display panel 24 and the cylindrical lens structure 25;

[0138] The flat layer 27 is located on the side of the cylindrical lens structure 25 away from the light-transmitting spacer layer 26 .

[0139] In some embodiments, when the display panel is a liquid crystal display panel, the display device further includes a backlight module located on the display panel away from the cylindrical lens structure.

[0140] In some embodiments, the display device further comprises:

[0141] Eye-tracking is used to determine the user's gaze area on the display device in real time.

[0142] In this way, the display information of each sub-pixel in the pixel island corresponding to the gaze area of ​​the user's eyes on the display device can be determined according to the determined gaze area of ​​the user's eyes on the display device.

[0143] In specific implementation, since the sub-pixel subdivision is performed in the pixel island (which can be used as a pixel for two-dimensional image (2D) display), the same resolution as 2D display can be maintained in the three-dimensional image (3D) display mode, and combined with eye-tracking, a multi-viewpoint display with a large viewing angle can be achieved, and a 3D display with a higher pixel density (ppi) can be achieved, with a larger amount of information, lower color crosstalk between adjacent viewpoints, and the user's dizziness when watching 3D images can be reduced, thereby improving the user experience. When the display device is provided with a cylindrical lens array, the cylindrical lens array can not only perform pixel mapping on the sub-pixels in the pixel island, but also perform light field modulation on the outgoing light of the pixel island, so that the final outgoing light of the pixel island forms multiple viewpoints, thereby realizing light field 3D display.

[0144] The display device provided in the embodiment of the present disclosure is any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a laptop computer, a digital photo frame, a navigator, etc. Other essential components of the display device should be understood by a person skilled in the art, and will not be described in detail here, nor should they be used as a limitation of the present disclosure. The implementation of the display device can refer to the embodiment of the display panel above, and the repeated parts will not be described in detail.

[0145] Based on the same inventive concept, the embodiment of the present disclosure also provides a driving method of the above display device, such as Figure 7 As shown, including:

[0146] S101, determining a current display mode, and determining in real time a gaze area of ​​a user's eyes on a display panel;

[0149] The driving method of the display device provided by the embodiment of the present disclosure can provide the signal of the same data input line to each coupled data line respectively by using the data selection circuit under the control of the signals of multiple data selection control lines, and can also provide the signals of different data input lines to the corresponding data lines respectively through different multiplexers. When multiple sub-pixels that need to be in the same row in each pixel island are combined for display and when the position of the human eye changes, the combined display sub-pixels also change. After determining the display information corresponding to each sub-pixel, even if the combined display sub-pixel changes, the display information of the combined display sub-pixel can be changed accordingly through the data selection circuit, so that the display information of the sub-pixel can be smoothly transitioned as the human eye moves, thereby improving the display effect and user experience.

[0150] In some embodiments, in step S101, determining in real time the gaze area of ​​the user's eyes on the display panel specifically includes:

[0154] A target sub-pixel in a pixel island corresponding to the view information is determined according to the view information, and display information of the target sub-pixel corresponding to the view information is determined.

[0155] In some embodiments, determining the current display mode specifically includes:

[0156] When the system resource occupancy of the display device meets the preset condition, determining that the current display mode is the first display mode; wherein in the first display mode, each sub-pixel in a sub-pixel row of the pixel island corresponds to a viewpoint;

[0157] When the system resource occupancy of the display device does not meet the preset conditions, the current display mode is determined to be the second display mode; in the second display mode, f adjacent sub-pixels in a sub-pixel row in the pixel island correspond to one viewpoint, wherein a sub-pixel row in the pixel island includes h sub-pixels, h / f is a positive integer; h and f are both positive integers greater than 1.

[0158] In a specific implementation, if the system resource occupancy of the display device meets the preset condition, the system resources of the display device are sufficient; if the system resource occupancy of the display device does not meet the preset condition, the system resources of the display device are insufficient.

[0159] In some embodiments, each data selection circuit includes a first multiplexer and a second multiplexer, the first multiplexer includes f first selection switches, and the second multiplexer includes f second selection switches;

[0160] When it is determined that the current display mode is the first display mode, providing a data selection control signal to the data selection control line according to the display information, and providing a data signal corresponding to the display information provided by the data write line to each data line corresponding to the pixel island in the gaze area through the data selection circuit, specifically including:

[0161] A first data selection control signal is provided to a plurality of data selection lines coupled to each first selection switch to control the f first selection switches in each data selection circuit to be turned on in sequence, and the data signal of the data input line coupled to the first poles of the f first selection switches is transmitted to the data line coupled to the second poles of the f first selection switches; at the same time, a second data selection control signal is provided to a plurality of data selection lines coupled to each second selection switch to control the f second selection switches in each data selection circuit to be turned off.

[0162] In some embodiments, when the first transistor in the first selection switch and the second transistor in the second selection switch are transistors of the same type, the first data selection control signal that controls the selection switch to be turned on is a high-level signal, and the second data selection control signal that controls the selection switch to be turned off is a low-level signal, or the first data selection control signal that controls the selection switch to be turned on is a low-level signal, and the second data selection control signal that controls the selection switch to be turned off is a high-level signal.

[0163] In specific implementation, Figure 1 Taking the display panel shown in FIG. 1 as an example, when it is determined that the current display mode is the first display mode, the corresponding timing diagram is as follows: Figure 8As shown, the first data selection control signal is sequentially provided to MU1, MU3, MU5, and MU7 to control the four first selection switches T11, T12, T13, and T14 in each data selection circuit 8 to be turned on sequentially. At the same time, the second data selection control signal is provided to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23, and T24 in each data selection circuit 8 to be turned off. Thus, for each data selection circuit 8 arranged sequentially from left to right, the first data selection circuit 8 inputs the data signal input by D0 to the corresponding data line through the first selection switch T11, T12, T13, T14, the second data selection circuit 8 inputs the data signal input by D1 to the corresponding data line through the first selection switch T11, T12, T13, T14, the third data selection circuit 8 inputs the data signal input by D2 to the corresponding data line through the first selection switch T11, T12, T13, T14, and the fourth data selection circuit 8 inputs the data signal input by D3 to the corresponding data line through the first selection switch T11, T12, T13, T14. In a specific implementation, Figure 1 One pixel island in corresponds to 16 viewpoints, and the correspondence between viewpoint P and sub-pixel can be, for example, as follows Figure 2 As shown, Figure 8 In the figure, di represents the data signal corresponding to the display information of the i-th viewpoint Pi in the pixel island. That is, D0 sequentially inputs data signals d1 to d4, D1 sequentially inputs data signals d5 to d8, D2 sequentially inputs data signals d9 to d12, and D3 sequentially inputs data signals d13 to d16. Figure 8 The ga signal is the scan line input signal.

[0164] In some embodiments, each row of sub-pixels in the pixel island is divided into a sub-pixel groups, where a=h / f, and each sub-pixel group includes f adjacent sub-pixels;

[0165] When it is determined that the current display mode is the second display mode, providing a data selection control signal to the data selection control line according to the display information, and providing a data signal corresponding to the display information provided by the data write line to each data line corresponding to the pixel island in the gaze area through the data selection circuit, specifically including:

[0166] When the display information of each sub-pixel in each sub-pixel group is the same, a first data selection control signal is provided to f data selection lines coupled to each first selection switch to control the f first selection switches in each data selection circuit to be turned on at the same time, and the data signal of the data input line coupled to the first pole of the f first selection switches is transmitted to the data line coupled to the second pole of the f first selection switches; at the same time, a second data selection control signal is provided to f data selection lines coupled to each second selection switch to control the f second selection switches in each data selection circuit to be turned off.

[0167] In specific implementation, Figure 1 Taking the display panel shown in FIG. 1 as an example, when it is determined that the current display mode is the second display mode, that is, Figure 1 In the example, four adjacent sub-pixels correspond to one viewpoint, that is, four adjacent sub-pixels are combined for display. When the display information of each sub-pixel in each sub-pixel group is the same, the correspondence between the viewpoint P and the sub-pixel can be, for example, as follows: Figure 3 The corresponding timing diagram is shown in Fig. 9 The first data selection control signal is provided to MU1, MU3, MU5, and MU7 simultaneously to control the four first selection switches T11, T12, T13, and T14 in each data selection circuit 8 to be turned on simultaneously, and the second data selection control signal is provided to MU2, MU4, MU6, and MU8 simultaneously to control the four second selection switches T21, T122, T23, and T24 in each data selection circuit 8 to be turned off. In this way, for each data selection circuit 8 arranged in sequence from left to right, the first data selection circuit 8 inputs the data signal input by D0 to the corresponding data line through the first selection switch T11, T12, T13, T14, the second data selection circuit 8 inputs the data signal input by D1 to the corresponding data line through the first selection switch T11, T12, T13, T14, the third data selection circuit 8 inputs the data signal input by D2 to the corresponding data line through the first selection switch T11, T12, T13, T14, and the fourth data selection circuit 8 inputs the data signal input by D3 to the corresponding data line through the first selection switch T11, T12, T13, T14. Fig. 9 In , di represents the data signal corresponding to the display information of the i-th viewpoint Pi in the pixel island, that is, D0 inputs d1 data signal, D1 inputs d2 data signal, D2 inputs d3 data signal, and D3 inputs d4 data signal.

[0168] In some embodiments, each data selection circuit includes a first multiplexer and a second multiplexer; when it is determined that the current display mode is the second display mode, a data selection control signal is provided to the data selection control line according to the display information, and a data signal corresponding to the display information provided by the data write line is provided to each data line corresponding to the pixel island of the attention area through the data selection circuit, specifically including:

[0169] When, in a part of the sub-pixel groups, the display information of the 1st to g-1th sub-pixels is the same, the display information of the gth to fth sub-pixels is the same, and the display information of the g-1th sub-pixel is different from the display information of the gth sub-pixel, a first data selection control signal is provided to a plurality of data selection lines coupled to each first selection switch to control the 1st to g-1th first selection switches to be turned on simultaneously, the gth to fth first selection switches to be turned on simultaneously, and the 1st to g-1th first selection switches and the gth to fth first selection switches to be turned on in sequence, so as to transmit the data signal of the data input line coupled to the first poles of the f first selection switches to the data line coupled to the second poles of the f first selection switches; at the same time, a second data selection control signal is provided to a plurality of data selection lines coupled to each second selection switch to control the f second selection switches in each data selection circuit to be turned off;

[0170] Among them, the data signal of each data input line when the 1st to g-1th first selection switches are turned on is different from the data signal when the g-th to f-th first selection switches are turned on; the data signal of the kth data input line when the g-th to f-th first selection switches are turned on is the same as the data signal of the k+1th data input line when the 1st to g-1th first selection switches are turned on.

[0171] The driving method of the display device provided in the embodiment of the present disclosure can change the merged display sub-pixels when the position of the human eye changes. After determining the display information corresponding to each sub-pixel, the data selection control signal provided by the data selection control signal line can be used to control the data selection circuit so that the display information of the merged display sub-pixels changes accordingly. This can make the display information of the sub-pixels transition smoothly as the human eye moves, thereby improving the display effect and enhancing the user experience.

[0172] It should be noted that g is an integer greater than or equal to 2 and less than f. When g is equal to 2, the display information of the second to f-th sub-pixels in each sub-pixel group is the same, and the display information of the second to f-th sub-pixels is different from the display information of the first sub-pixel.

[0173] In a specific implementation, when it is determined that the current display mode is the second display mode, and when the user's eyes move, relative to Figure 3Move one sub-pixel to the right, that is, g=2, and the correspondence between the viewpoint P and the sub-pixel can be, for example, as follows: Figure 4 The corresponding timing diagram is shown in Fig.10 As shown, Fig.10 In the figure, di represents the data signal corresponding to the display information of the i-th viewpoint Pi in the pixel island. That is, D0 sequentially inputs data signals d4 and d1, D1 sequentially inputs data signals d1 and d2, D2 sequentially inputs data signals d2 and d3, D3 sequentially inputs data signals d3 and d4, and D4 sequentially inputs data signals d4 and d1. Provide a first data selection control signal to MU1, and then provide a first data selection control signal to MU3, MU5, and MU7 at the same time to control T11 in each data selection circuit 8 to turn on first, and then T12, T13, and T14 to turn on at the same time. At the same time, provide a second data selection control signal to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23, and T24 in each data selection circuit 8 to turn off. In this way, it can be achieved Figure 4 The corresponding merge display scheme.

[0174] In a specific implementation, when it is determined that the current display mode is the second display mode, and when the user's eyes continue to move, the gaze area is relative to Figure 4 Move one sub-pixel to the right, that is, g=3, the correspondence between the viewpoint P and the sub-pixel can be, for example, Figure 5 The corresponding timing diagram is shown in Fig.11 As shown, Fig.11 In the figure, di represents the data signal corresponding to the display information of the i-th viewpoint Pi in the pixel island. That is, D0 sequentially inputs data signals d4 and d1, D1 sequentially inputs data signals d1 and d2, D2 sequentially inputs data signals d2 and d3, D3 sequentially inputs data signals d3 and d4, and D4 sequentially inputs data signals d4 and d1. At the same time, a first data selection control signal is provided to MU1 and MU3, and then a first data selection control signal is provided to MU5 and MU7 simultaneously to control T11 and T12 in each data selection circuit 8 to be turned on simultaneously first, and then T13 and T14 to be turned on simultaneously. At the same time, a second data selection control signal is provided to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23, and T24 in each data selection circuit 8 to be turned off. In this way, it can be achieved Figure 5 The corresponding merge display scheme.

[0175] It should be noted that if Fig.10 , Fig.11As shown, only one set of data selectors in the data selection circuit is used, and different data signals can be provided to a sub-pixel group through the data selector by adjusting the timing. However, in the second display mode, the refresh frequency of the display device needs to be doubled, which affects the power consumption of the display device when the system resources of the display device are insufficient.
