[0034] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.
[0035] A touch screen (or, it can also be called a display device) is also called a "touch screen" or a "touch panel", which is an inductive liquid crystal display device capable of receiving input signals of a touch head, etc. When a graphical button on the screen is touched, a tactile feedback system on the screen can drive various connected devices according to a pre-programmed program, which can replace a mechanical button panel and create vivid audio-visual effects through a liquid crystal display screen.
[0036] Figure 1 is a schematic diagram of an application scenario of a display device provided by an embodiment of the present application. As shown in Figure 1 , the display device can be applied in the fields of display, tablet computer, portable computer, etc. As an input device, the display device is a simple, convenient and natural human-computer interaction mode. It gives multimedia a brand-new look and is a new multimedia interaction device with great attraction.
[0037] With the popularization of electronic products, users increasingly pursue the interactive experience performance of electronic products, therefore, the demand of users for large-screen teaching, large-screen conference, large-screen writing and drawing, etc. is also stronger, and then higher requirements are put forward for the touch precision and large size of the display device.
[0038] The capacitive display device works by using the current induction of the human body. When a conductive object touches the glass surface, the capacitance of the touch point changes, so that the position of the touch can be detected. Although the capacitive display device has high touch accuracy and strong anti-interference performance, it cannot realize a large-size display device with high touch accuracy. This is because when the touch accuracy of the capacitive display device is improved, the touch detection time of the capacitive display device is increased, thereby reducing the pixel charging time, resulting in insufficient charging time of the far-end pixel, and color deviation.
[0039] In view of the technical problem, the embodiments of the present application provide a picture display method and a display device, which can solve the problem of insufficient charging time of the far-end pixel of the display device, thereby meeting the dual requirements of high touch accuracy and large size of the display device.
[0040] In the following, the picture display method provided by the embodiments of the present application will be described in conjunction with Figure 2 and Figure 3 .
[0041] It should be noted that the first picture is the basic unit of the display device displaying a picture. In addition, the first picture corresponds to the pixel (also referred to as the pixel point), that is, one picture corresponds to a certain number of pixels, or one picture corresponds to a certain number of pixel points. In order to describe the technical solutions of the embodiments of the present application, the picture display method is described by using the pixel.
[0042] It should be understood that the picture display method described in the embodiments of the present application can be applied to a display device, which includes an image processing chip, a first timing control chip, a second timing control chip, a first driving chip set, and a second driving chip set. The first driving chip set is used to drive a pixel array of a display panel, each first driving chip in the first driving chip set is used to drive at least one column / row of pixels in the display panel, the second driving chip set is used to drive the pixel array, and each second driving chip in the second driving chip set is used to drive at least one column / row of pixels in the display panel.
[0043] Figure 2 is a schematic flowchart of the picture display method provided by the embodiments of the present application. As shown in Figure 2 .
[0044] In S210, the image processing chip acquires a first picture, divides the first picture along a first direction to obtain a first sub-picture and a second sub-picture, and respectively performs image superposition on the first sub-picture and the second sub-picture to generate a second picture and a third picture, wherein the second picture and the third picture have at least a partially overlapped region.
[0045] Specifically, the image processing chip receives a first picture, and divides the first picture along a first direction to obtain a first sub-picture and a second sub-picture; the image processing chip is further configured to perform image overlap on the first sub-picture and the second sub-picture respectively, and accordingly obtain a second picture and a third picture, and the second picture and the third picture have at least a partially overlapped region. After that, the image processing chip transmits the second picture and the third picture to a first time sequence control chip and a second time sequence control chip respectively, specifically, the image processing chip transmits the second picture to the first time sequence control chip, and transmits the third picture to the second time sequence control chip, so that the second picture corresponds to the first time sequence control chip, and the third picture corresponds to the second time sequence control chip.
[0046] It should be understood that the second picture corresponds to the first sub-picture, and the third picture corresponds to the second sub-picture.
[0047] It should be understood that the first direction can be a vertical direction or a horizontal direction. Meanwhile, the process of dividing the first picture along the first direction by the image processing chip is equivalent to the process of partition transmission of the first picture by the image processing chip.
[0048] It should be understood that the first picture corresponds to a plurality of pixels of the display panel, which can be understood as that the plurality of pixels corresponding to the first picture can be all the pixels of the display panel, or can be part of the pixels, and the embodiments of the present application are not limited specifically.
[0049] It should be understood that the overlapping degree of the partially overlapped region between the second picture and the third picture can be 30%, can be 50%, or can be 100%, and the embodiments of the present application do not limit the picture overlapping degree between the second picture and the third picture specifically.
[0050] It should be understood that the picture overlapping degree refers to the proportion of the overlapped picture region to the original picture, and when the picture overlapping degree is 100%, it means that the second picture and the third picture are identical pictures, that is, the first picture, the second picture and the third picture are the same picture (all are the first picture).
[0051] As a possible implementation manner, when the image overlapping region between the second picture and the third picture is 100%, the second picture is equivalent to the first picture, and the third picture is equivalent to the first picture, and the picture overlapping region between the second picture and the third picture is the entire content of the first picture.
[0052] Exemplarily, the first picture corresponds to 3840 (columns) * 2160 (rows) pixels, the image processing chip divides the first picture into a first sub-picture and a second sub-picture, the first sub-picture corresponds to 1920 (columns) * 2160 (rows) pixels, and the second sub-picture corresponds to 1920 (columns) * 2160 (rows) pixels. The image processing chip respectively performs image superposition on the first sub-picture and the second sub-picture to generate a second picture and a third picture, and the overlapping picture area between the first sub-picture and the second sub-picture is defined as 1920 (columns) * 2160 (rows) pixels. Therefore, the second picture corresponds to 3840 (columns) * 2160 (rows) pixels, and the third picture corresponds to 3840 (columns) * 2160 (rows) pixels.
[0053] The following will be described in combination with Figure 3 the partition transmission shown in Figure 2 .
[0054] Figure 3 is a schematic diagram of a partition transmission provided by an embodiment of the present application. As shown in Figure 3 , the image processing chip of the display device divides the area where the first picture needs to be displayed into two partitions, and transmits two sub-pictures (that is, the left partition corresponds to the first sub-picture, and the right partition corresponds to the second sub-picture) by the left and right two partitions. Each partition corresponds to 1920 (columns) * 2160 (rows) pixels, and the overlapping picture area is set as 1920 (columns) * 2160 (rows) pixels. In this way, the second picture actually transmitted by the left partition corresponds to the sum of 1920 (columns) * 2160 (rows) pixels of the non-overlapping picture area and 1920 (columns) * 2160 (rows) pixels of the overlapping picture area, that is, 3840 (columns) * 2160 (rows) pixels (the complete first picture) are actually transmitted. Similarly, the right partition also actually transmits the complete first picture.
[0055] It should be noted that Figure 3 the partition transmission shown in is a partition transmission along the vertical direction, but the partition transmission can be a partition transmission along the horizontal direction, and the embodiments of the present application do not make specific limitations.
[0056] S220, the first timing control chip controls the first driving chip set to drive the pixels in the pixel array corresponding to the second picture to display according to the second picture.
[0057] S230, the second timing control chip controls the second driving chip set to drive the pixels in the pixel array corresponding to the third picture to display according to the third picture.
[0058] Specifically, after the image processing chip performs partition transmission and image overlap processing on the first picture, the second picture and the third picture are generated, and the second picture and the third picture are transmitted to the first timing control chip and the second timing control chip respectively. The first timing control chip controls the first driving chip set to drive the pixels corresponding to the second picture in the pixel array of the display panel to display according to the second picture; and the second timing control chip controls the second driving chip set to drive the pixels corresponding to the third picture in the pixel array of the display panel to display according to the third picture.
[0059] It should be understood that after the first driving chip set and the second driving chip set drive the pixels corresponding to the second picture and the third picture respectively, the second picture and the third picture are displayed on the display panel respectively, so as to finally complete the display of the first picture.
[0060] By the picture display method, the embodiment of the present application can divide the first picture into the first sub-picture and the second sub-picture, and perform image overlap on the first sub-picture and the second sub-picture respectively to obtain the corresponding second picture and third picture. There is a partially overlapped picture area between the second picture and the third picture. The second picture corresponds to the first timing control chip, and the third picture corresponds to the second timing control chip. Each timing control chip corresponds to a driving chip set. In this way, each pixel in the overlapped picture area of the second picture and the third picture is bidirectionally driven. In other words, each pixel in the overlapped area is bidirectionally charged. In this way, the charging rate of each pixel in the overlapped area is balanced, and the color deviation between pixels is minimized. In this way, the embodiment of the present application can meet the dual requirements of high touch precision and large size of the display device.
[0061] More specifically, by realizing bidirectional charging of each pixel, the embodiment of the present application can ensure that the charging rate of each pixel of the display device is balanced. In this way, when a large-size display device is prepared, the charging time of the far-end pixel of the display device is not insufficient, thereby reducing the touch precision of the display device, so as to meet the dual requirements of high touch precision and large size of the display device.
[0062] As a possible implementation manner, the first timing control chip inserts at least one row of blanking row into the second picture along the second direction, and the second timing control chip inserts at least one row of blanking row into the third picture along the second direction.
[0063] It should be understood that the first timing control chip and the second timing control chip respectively insert at least one row of blanking row into the second picture and the third picture along the second direction, and the at least one row of blanking row is not used for picture display.
[0064] Specifically, when the first timing control chip inserts the at least one line of blanking lines into the second picture along the second direction, the at least one line of blanking lines can be distributed between the multiple lines of data lines corresponding to the second picture in a staggered manner, for example, one line of data lines followed by one line of blanking lines, or at least two lines of data lines followed by one line of blanking lines, or one line of data lines followed by at least two lines of blanking lines, or at least two lines of data lines followed by at least two lines of blanking lines, and the like. The present application does not limit the distribution of the at least one line of blanking lines in the second picture. The process of inserting the at least one line of blanking lines into the third picture along the second direction by the second timing control chip is as described above.
[0065] It should be understood that each line of data line in the multiple lines of data lines can be used for picture display or other purposes, such as control information. Therefore, the data line can be a display data line, a control data line, or other types of data line, but the blanking line is not used for picture display, i.e., the blanking line is not a display data line.
[0066] Specifically, each line of blanking line in the at least one line of blanking line is used for non-picture display. It can be understood that when the display device receives picture data, a line of blanking line is inserted after each line of data line, and the blanking line is not used for actual picture display. During the time period corresponding to each line of blanking line, the display device is not used for picture display, but for other purposes, such as audio playback or touch detection.
[0067] By inserting the at least one line of blanking line into the second picture and the third picture by the first timing control chip and the second timing control chip respectively, the total number of lines corresponding to the second picture and the third picture respectively can be increased. For example, the second picture corresponds to 100 lines * 100 columns, and after the first timing control chip inserts 100 lines of blanking lines, the second picture corresponds to 200 lines * 100 columns. In the time period corresponding to the newly added 100 lines of blanking lines, other purposes such as audio playback can be realized.
[0068] As a possible implementation manner, the display device further includes a touch detection chip, and the method of displaying a picture further includes:
[0069] The touch detection chip detects whether the pixels corresponding to the second picture and the third picture in the pixel array are touched in the time period corresponding to the at least one line of blanking line.
[0070] By detecting whether the pixels of the second picture and the third picture are touched at the pixel level by the touch detection chip in the time period corresponding to the at least one line of blanking line, the touch accuracy of the display device can be further improved.
[0071] As a possible implementation manner, the first picture can also be a partial picture of a complete picture, that is, the first picture acquired by the image processing chip is a part of the complete picture to be displayed by the display panel, instead of the whole picture.
[0072] As a possible implementation manner, the first direction is perpendicular to the second direction, or the first direction is the same as the second direction, where the first direction is a vertical direction or a horizontal direction.
[0073] As a possible implementation manner, each first driving chip in the first driving chip group drives the same pixel as each second driving chip in the second driving chip group.
[0074] As a possible implementation manner, the display device further includes the display panel.
[0075] As a possible implementation manner, the first driving chip group and the second driving chip group are arranged on the upper and lower sides of the display panel respectively, or the first driving chip group and the second driving chip group are arranged on the left and right sides of the display panel respectively.
[0076] It should be particularly noted that in the embodiments of the present application, the image processing chip of the display device can not only divide the first picture along the first direction to obtain the first sub-picture and the second sub-picture, but also divide the first picture along the first direction to obtain a plurality of sub-pictures. When the image processing chip divides the first picture to obtain a plurality of sub-pictures, the number of the timing control chips is consistent with the number of the sub-pictures, and the number of the driving chip groups is also consistent with the number of the timing control chips.
[0077] More specifically, when the image processing chip divides the first picture to obtain N pictures through partition transmission and image overlap, each picture in the N pictures corresponds to a timing control chip, and each timing control chip corresponds to a driving chip group, where N is a positive integer greater than 2, that is, there are as many timing control chips and driving chip groups as there are pictures. In this way, the embodiments of the present application can realize multi-directional charging (N-directional charging) of each pixel in the image overlap area.
[0078] The display device of the embodiments of the present application will be described below in conjunction with Figure 4 and 5 .
[0079] Figure 4 is a structural schematic block diagram of a display device provided by the embodiments of the present application. As shown in Figure 4 , the display device of the embodiments of the present application includes:
[0080] The image processing chip, the first timing control chip, the second timing control chip, the first driving chip set, the second driving chip set, the first driving chip set is used for driving a pixel array of the display panel, each first driving chip in the first driving chip set is used for driving at least one column / row of pixels in the display panel respectively, and the second driving chip set is used for driving the pixel array, each second driving chip in the second driving chip set is used for driving at least one column / row of pixels in the display panel respectively.
[0081] It should be understood that the first driving chip set can be arranged in the upper side region of the display panel, the second driving chip set can be arranged in the lower side region of the display panel, and the number of driving chips included in each driving chip set is the same, for example, each driving chip set includes 24 driving chips, that is, the display device includes two driving chip sets, each driving chip set includes 24 driving chips, and the arrangement positions of the two driving chip sets can be one-to-one corresponding.
[0082] It should be noted that, as described above, when the image processing chip divides the first picture along the first direction to obtain N sub-pictures, the display device includes N timing control chips and N driving chip sets, and the specific arrangement mode of the N driving chip sets is not limited in the embodiment of the application, which can be arranged according to specific scenes. For example, when N is 4, the four driving chip sets can be arranged on the four sides of the display panel, i.e., the upper side, the lower side, the left side and the right side.
[0083] Figure 5 is another structural schematic block diagram of a display device provided by the embodiment of the application. As shown in the figure, the display device of the embodiment of the application includes: Figure 5
[0084] The image processing chip is used for acquiring a first picture, dividing the first picture along a first direction to obtain a first sub-picture and a second sub-picture, and performing image overlap on the first sub-picture and the second sub-picture respectively to generate a second picture and a third picture, wherein the second picture and the third picture have at least a partially overlapped region.
[0085] The first timing control chip is used for controlling the first driving chip set to drive pixels corresponding to the second picture in the pixel array to display according to the second picture.
[0086] The second timing control chip is used for controlling the second driving chip set to drive pixels corresponding to the third picture in the pixel array to display according to the third picture.
[0087] The related description of the first picture, the second picture and the third picture can be referred to the foregoing content, which will not be described here.
[0088] Specifically, the image processing chip has a partition transmission and image overlap function. After the first picture is divided into two sub-pictures, a first sub-picture and a second sub-picture are obtained, and image overlap is performed on the first sub-picture and the second sub-picture respectively to generate a second picture and a third picture. Then, the image processing chip transmits the second picture and the third picture to the first time sequence control chip and the second time sequence control chip, and the corresponding first driving chip set and the second driving chip set drive the corresponding pixels, so that the second picture and the third picture are displayed on the display panel.
[0089] As a possible implementation, the display device further includes a touch detection chip configured to detect whether the pixels corresponding to the second picture and the third picture in the pixel array are touched in a time period corresponding to the at least one row of blanking lines.
[0090] Specifically, the touch detection chip detects whether the pixels of the second picture and the third picture are touched at the pixel level in the time period corresponding to the at least one row of blanking lines, so that the touch accuracy of the display device can be further improved.
[0091] As a possible implementation, the display device further includes a data transmission chip configured to be responsible for data transmission between the image processing chip and the first time sequence control chip and the second time sequence control chip.
[0092] It should be understood that Figure 5 The image processing chip, the time sequence control chip, and the driving chip in the display device shown are described as a high-level description, which can correspond to other devices or equipment or chips and the like for realizing the method of displaying the picture. Figure 2 The method of displaying the picture shown.
[0093] As an exemplary description, the image processing chip is a system on chip (SOC) chip, and the time sequence control chip is a time controller (TCON) chip, where the number of the TCON chips is related to the number of sub-pictures obtained by dividing the first picture along the first direction.
[0094] Specifically, the SOC chip is configured to receive and process the first picture to be displayed on the screen. The processing manner is to divide the first picture into two sub-pictures, and perform image overlap on the first sub-picture and the second sub-picture to obtain the second picture and the third picture. There is a partially overlapping area between the second picture and the third picture. In other words, the SOC chip supports the partition transmission function and the image overlap function.
[0095] After the SOC chip completes the partition transmission and image superposition function on the first picture, the second picture and the third picture are obtained, and then the second picture and the third picture are transmitted to the corresponding two TCON chips. There is a primary and secondary distinction between the two TCON chips, that is, there is a TCON master chip, and the remaining one is a TCON slave chip. The TCON master and slave chips can communicate with each other, and the TCON master chip generates a synchronization signal, thereby realizing the synchronous driving of the two TCON chips on the pixels corresponding to the first picture.
[0096] It should be understood that the TCON chip is used to receive the picture required for screen display and transmit the picture to the display panel, and supports the function of inserting a blanking row.
[0097] Exemplarily, after receiving a certain number of data rows, the TCON chip inserts a certain number of blanking rows, and the number of data rows and the number of blanking rows can be 1 row, 2 rows, or multiple rows. The number of data rows and the number of blanking rows do not have to be the same, for example, the TCON chip inserts one blanking row after receiving one data row, or the TCON chip inserts one blanking row after receiving two data rows, or the TCON chip inserts one blanking row after receiving three data rows, or the TCON chip inserts four blanking rows after receiving two data rows. The application embodiment does not make specific limitations on the form of the interval distribution between the data rows and the blanking rows. It should be understood that the data row can be a display data row, a control data row, or other types of data rows.
[0098] More specifically, the TCON chip supporting the insertion of a blanking row is equivalent to: the TCON chip divides the received data rows into multiple data regions, and each data region includes a blanking area. Exemplarily, if the TCON chip needs to receive a total of 2160 data rows, the TCON chip can divide the 2160 data rows into 16 data regions, each data region includes 135 data rows, and a blanking area including multiple blanking rows is inserted after each data region. The number of blanking rows included in the blanking area can be consistent with the number of data rows included in the data region, or it can not be consistent.
[0099] It should be understood that when the TCON chip outputs a blanking row signal, the TCON chip will stop receiving data rows; when the TCON chip outputs a data row signal, the TCON chip will continue to receive data rows, so that a frame of data scanning can be repeatedly completed.
[0100] It should be understood that in the embodiments of the present application, each group of drive chips includes a plurality of drive chips, which are used to actually drive the pixels corresponding to the first picture, and each drive chip controls a certain number of pixels arranged inside the display panel. For example, each group of drive chips includes 24 drive chips.
[0101] It should be noted that in the embodiments of the present application, the number of groups of drive chips is related to the number of TCON chips. For example, when the TCON chips are two, the display device includes two groups of drive chips, and each TCON chip is responsible for driving a group of drive chips; or when the TCON chips are four, the display device includes four groups of drive chips, and each TCON chip is responsible for driving a group of drive chips.
[0102] It should be noted that in the embodiments of the present application, the specific arrangement of the two groups of drive chips can be uniformly arranged on the upper and lower sides of the display panel, or on the left and right sides, and the number of drive chips in each group of drive chips can be the same or different.
[0103] It should be noted that the embodiments of the present application do not limit the specific arrangement of each drive chip in the plurality of groups of drive chips.
