The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
An embodiment of the present application provides a display panel, as shown in fig. 1, the display panel includes: a control module 200 and at least one display area 100.

Each signal output unit 210 is electrically connected to each GOA circuit 300 and each acquisition module 400 of the corresponding display area 100, and is configured to output a GOA signal and a corresponding acquisition signal to each GOA circuit 300 and each acquisition module 400, respectively.
Each GOA circuit 300 of the display area 100 is configured to control the plurality of pixel circuits of the display area 100 to be turned on line by line when receiving the GOA signal.
Each acquisition module 400 of the display area 100 is configured to, when receiving a corresponding acquisition signal, synchronously acquire pixel data of a pixel circuit that is turned on in each row to obtain first sub-image information; the first sub-picture information of each display area 100 is used for stitching into the picture information of the display panel. The image information of the display panel is information of a complete image which needs to be acquired by the whole display panel.
Optionally, referring to fig. 1, the control module 200, the GOA circuit 300, and the acquisition module 400 are all located in the non-display area, and are correspondingly disposed in the peripheral area of the display area 10.

The embodiment of the application adopts at least two acquisition modules 400 to acquire data synchronously, thereby reducing the quantity of image information acquired by each acquisition module 400, reducing the digital acquisition time, effectively realizing the improvement of the acquisition frame rate by cooperating with the GOA (Gate Driver on Array, Array substrate Gate drive) signal control, avoiding the problem of slow or unsmooth human-computer interaction reaction, and improving the user experience.
The display panel of the embodiment of the application can output the GOA signal and the corresponding acquisition signal to each GOA circuit 300 and each acquisition module 400 respectively through the control module 200, and the control module 200 can control the GOA circuit 300 and the acquisition module 400 respectively, so that the acquisition module 400 can not have the GOA function, the control module 200 can control the acquisition modules 400 synchronously, and the rapid acquisition of the image information is realized.
Optionally, in the embodiment of the present application, at least two acquisition modules 400 without a GOA function, which are used to increase the frame rate, are used, and under the cooperative control of the source and gate signals, the frame rate of the acquired images is effectively increased.
Optionally, referring to fig. 1, a structure and a connection relationship of one display area 100 are shown, and two acquisition modules 400 and two GOA circuits 300 are correspondingly disposed in the display area 100. It is conceivable that the display area 100 may be further provided with more than two acquisition modules 400 according to the actual acquisition frame rate requirement.
Optionally, the acquisition module 400 is an acquisition IC (Integrated Circuit) chip.
Optionally, the display panel of the embodiment of the application is suitable for the relevant field of human-computer interaction of the spliced large screen.
The inventor considers that the human-computer interaction technology is realized for a large screen formed by splicing a plurality of pieces, a high image frame rate is required to be guaranteed for better user experience and quick interaction, and if the frame rate is too low, the problem of slow human-computer interaction reaction or blockage occurs, so that the user experience is greatly influenced. However, the gate of the panel design mostly adopts the GOA design at present, which requires the source acquisition IC to support the GOA, and the GOA signal is automatically controlled inside the acquisition IC, so the frame rate is fixed, and it is difficult to increase the frame rate.
Based on the above consideration, the control module 200 according to the embodiment of the present application implements the control of the GOA signal, and then converts the first level signal into the second level signal required by the display panel through the level conversion subunit 212, and implements the synchronous control with the acquisition IC without the GOA function, thereby implementing the fast acquisition of the image data.
In some embodiments, referring to fig. 2, the signal output unit 210 includes a signal control subunit 211 and a level conversion subunit 212.
The signal control subunit 211 is electrically connected to each acquisition module 400 corresponding to the display area 100, and is configured to output an acquisition signal to each acquisition module 400;
the level shift subunit 212 is electrically connected to the signal control subunit 211 and each of the GOA circuits 300 corresponding to the display area 100, and is configured to convert the first level signal output by the signal control subunit 211 into a second level signal, and output the second level signal as a GOA signal to each of the GOA circuits 300; the level of the second level signal is higher than the level of the first level signal.
Optionally, the signal output unit 210 in the embodiment of the present application outputs the acquisition signal and the GOA signal through the signal control subunit 211 and the level conversion subunit 212, so that cooperative control of the acquisition module 400 and the GOA circuit 300 is realized, an increase in the acquisition frame rate is effectively realized, a problem of slow or unsmooth human-computer interaction reaction is avoided, and user experience is improved.
Optionally, a level shift subunit 212 is added to the signal output unit 210, and the level shift subunit 212 may be a level conversion circuit, so that the signal output unit 210 can flexibly control gate and source signals.
Optionally, the level shift circuit is a typical level shifter circuit, and mainly comprises an NMOS and two pull-up resistors, and the function is bidirectional. When the NMOS is inputted with a high level of 3.3V at its S-pole (source), the NMOS does not conduct, and since its D-pole (drain) is pulled up to 5V, the diode does not conduct either, so that its output is at 5V level. When the S pole input of the NMOS is low level 0V, the NMOS is turned on, and the D pole output is pulled to 0V. This achieves a level transition from left to right. When the D input of the NMOS is high at 5V, it is pulled up to 3.3V through the 4.7k resistor due to its S. Therefore, both the NMOS and the diode at the back are not turned on, and thus the level of the S-pole is 3.3V, and when the input of the D-pole of the NMOS is low level of 0V, the level of the S-pole is 0V because the diode at the back is turned on.
In some embodiments, as shown in fig. 3, the control module 200 further includes a data synchronization unit 220.
The data synchronization unit 220 is electrically connected to all the acquisition modules 400, and is configured to perform synchronization processing on the first sub-image information acquired from each acquisition module 400 of each display area 100 to obtain second sub-image information.
In some embodiments, referring to fig. 3, the control module 200 further comprises an image stitching unit 230.
And the image stitching unit 230 is electrically connected to the data synchronization unit 220, and is configured to correspondingly stitch the second sub-image information to obtain third image information corresponding to all the display areas 100, which is used as image information of the display panel.
In some embodiments, referring to fig. 4, the control module 200 further includes an interactive algorithm processing unit 230 electrically connected to the image stitching unit 230 for performing algorithm processing and interactive control according to the third image information.
The acquisition frame rate of the display panel is greatly improved, the reaction time of an interaction algorithm is prolonged, the user experience is smoother, and the competitiveness of the product is effectively improved.
Optionally, referring to fig. 4, the display panel further includes a clock control module 500 electrically connected to the control module 200, and configured to output a clock signal to the control module 200, so as to facilitate logic calculation performed by the control module 200. The clock control module 500 can provide a clock source for the control module 200, so that the modules of the control module 200 can realize corresponding functions.

In some embodiments, as shown in FIG. 5, the display panel includes four display regions 100.
The four display areas 100 are arranged adjacently in pairs along the first direction and the second direction; the first direction is perpendicular to the second direction. The first direction is vertical in the figure, and the second direction is horizontal in the figure.
The control module 200 includes two signal output units 210; the two signal output units 210 are disposed at two sides of the display area 100 in the first direction, and each signal output unit 210 is electrically connected to two adjacent display areas 100.
Alternatively, the control module 200 may also include only one signal output unit 210, and the signal output unit 210 is electrically connected to each of the acquisition modules 400 and each of the GOA circuits 300 of each of the display regions 100, that is, all the acquisition modules 400 and the GOA circuits 300 may be controlled by one signal output unit 210.
Alternatively, referring to fig. 5, one GOA circuit 300 is disposed on each side of each display area 100 along the second direction.
The inventor of the application finds that the digital acquisition time of one line of the acquisition IC with the GOA is 50us, the acquisition IC is changed into two common acquisition ICs to acquire one line of data at the same time, the digital acquisition time of one line only needs 25us, so that the acquisition time is shortened by half from the time, the corresponding frame rate is improved a lot, theoretically, the more the common acquisition ICs are, the higher the frame rate is, and the cost is also high.
Based on the above consideration, in the embodiment of the present application, the acquisition module 400 that does not support the GOA is adopted, and the control signals of the gate and the source are controlled and generated by the signal output unit 210, so that the number of the acquisition modules 400 is increased, the acquisition bandwidth of the image is increased, the digital acquisition time is reduced, and the frame rate of the acquired image is increased.
As an example, in some embodiments, referring to fig. 5, two acquisition modules 400 are provided for each display area 100.
Each acquisition module 400 is configured to, when receiving a corresponding acquisition signal, respectively and synchronously acquire pixel data of half of the pixel circuits that are turned on in each row, so as to obtain first sub-image information.
Alternatively, each acquisition module 400 acquires half of each row of pixel data, and two acquisition modules 400 may acquire the entire row of pixel data.
Alternatively, referring to fig. 6, based on the structure of the display panel in fig. 5, the acquisition timing sequence of the acquisition module 400 and the GOA circuit 300 is as follows: the first row is started, and analog control of the circuit is firstly carried out, wherein the analog control mainly comprises signal acquisition and GOA signal control. After the analog control is finished, a line of data is synchronously acquired by the two acquisition modules 40, so that half of the digital acquisition time is saved. And after the acquisition of the first row is finished, starting the analog control of the second row, and after the acquisition of the second row is finished, performing digital acquisition until the acquisition of the Nth row is finished, thereby finally finishing the acquisition of one frame of data.

And the upper computer 600 is in communication connection with the display panel and is used for obtaining an image acquisition frame rate and a corresponding display image according to the first sub-image information of each acquisition module 400.
Alternatively, referring to fig. 7, the control module 200 includes a data synchronization unit 220 and an image stitching unit 230. The upper computer 600 is electrically connected with the image stitching unit 230 and is used for obtaining the image acquisition frame rate and the corresponding display image according to the third image information output by the image stitching unit 230.
As an example, in the embodiment of the present application, an image acquisition system is used to test an acquisition frame rate of a display panel, the image acquisition system takes a fingerprint acquisition system as an example, the control module 200 controls 3 ROIC _512 (i.e., the acquisition module 400) and 2 GATE ICs (i.e., the GOA circuit 300) to realize panel area acquisition with a resolution of 1600x1536, line _ time of each line is 195us, and control logic of the main control chip is simultaneously started at analog time of each line, so that 3 ROIC _512 share the same analog time, and after analog control is finished, digital acquisition is performed. The method comprises the steps that 3 ROIC _512 synchronously acquire a line of data information and a line of 1536 pixel points, the data acquisition section of a first ROIC (namely an acquisition module 400) is 0-511, the data acquisition section of a second ROIC is 512-1023, the data acquisition section of a third ROIC is 1024-1535, the data acquisition is completed in the same digital time, the time is 150us, the analog time is 45us, the line number is 1600, and the image acquisition frame rate is 1/(1600x195us) ≈ 3.2 frames.
As another example, based on the above image acquisition system, the embodiment of the present application replaces ROIC with 6 256 channels, and the GTAE IC is not changed, so that the acquisition of one line of data by 3 ROICs is changed into the acquisition of 6 ROICs. The synchronous panel end adopts a bonding6 ROIC structure, a circuit is correspondingly modified with a pin of a main control chip, then a control logic of the main control chip is started at the same time in the simulation time of each row, so that 6 ROICs share the same simulation time, after the simulation control is finished, digital acquisition is carried out, 6 ROICs synchronously acquire data information of one row, one row is 1536 pixel points, the first ROIC acquisition data section is 0-255, the second ROIC acquisition data section is 256-511, the third ROIC acquisition data section is 512-767, the fourth ROIC acquisition data section is 768-1023, the fifth ROIC acquisition data section is 1024-1279, the sixth ROIC acquisition data section is 1280-1535, the acquisition is completed in the same digital time, the time is 75us, is half of the ROIC _512 digital time (the channel is halved), the analog time is 45us, and the frame rate is 1600x 120.84/(355) frames on the basis of the same row line, compared with the original example, the frame rate is improved by 2 frames/s, and the improvement effect is very obvious.
Optionally, the display panel of the embodiment of the present application may determine feasibility of increasing the frame rate of acquisition through verification on the fingerprint acquisition system. As the number of ROICs increases, the acquisition frame rate is gradually increased. In practical applications, the space for bonding the panel bindable is also limited and the cost requirement is considered, and the number of ROICs, that is, the number of the acquisition modules 400, is reasonable.
