The conventional time sequence control circuit outputs three signals to the data driving circuit, including a data synchronizing signal (TP), a direction control signal and a differential signal, and finally the data driving circuit outputs to the grid circuit and the source circuit to start so as to realize the picture display.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.

It should be noted that the following is a simple description of the background of the present solution:

it can be understood that each row of liquid crystals in the liquid crystal display panel is composed of thin film transistors, after the thin film transistors are turned on by the gate circuit, the source circuit is responsible for charging, during this period, the backlight module on the back of the liquid crystal display panel is responsible for providing illumination of the light source, and each pixel of the liquid crystal is responsible for passing light or not and the number of the passing light, so that a color image is formed under the cooperation of the color filters. This is a display principle of a general liquid crystal panel.

In order to solve the above technical problems, embodiments of the present application provide a driving method of a display panel. By utilizing the display panel driving method provided by the embodiment of the application, the data synchronizing signals output by the time sequence control circuit are rewritten, so that the original data synchronizing signals are converted into a plurality of data synchronizing signals, and each data synchronizing signal can be set with different charging time lengths, so that the charging time of different areas of the display panel is changed under the condition that the CK (clock) output signals of GOA (gate drive on array substrate) are unchanged, and the color cast problem caused by insufficient charging of pixel units is solved.

Referring to fig. 1, fig. 1 is a flow chart of a driving method of a display panel according to an embodiment of the disclosure. The display panel driving method is applied to terminal equipment. Optionally, the terminal device is a terminal or a server. Optionally, the server is an independent physical server, or a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligence platforms, and the like. Optionally, the terminal is a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a smart voice interaction device, a smart home appliance, a vehicle-mounted terminal, and the like, but is not limited thereto.

In one embodiment, the display panel driving method is implemented based on a display panel including a plurality of gate lines and source lines, and a plurality of pixel units arranged in a matrix form defined by intersections of the gate lines and the source lines, each row of liquid crystals being composed of thin film transistors (TFTs, thin Film Transistor). The plurality of pixel units are divided into n partitions from top to bottom. The method may comprise the steps of:

step 101, receiving a gate line control signal, a source line control signal and a data signal sent by a time sequence control circuit according to a preset time sequence, wherein the source line control signal comprises a plurality of data synchronization signals, and the plurality of data synchronization signals respectively correspond to different partitions so as to adjust charging time lengths of the different partitions.

It should be noted that the pixel units described in this embodiment are distributed on the display panel based on the trigger architecture. In the trigger architecture, each pixel is driven by one data line and three gates, which is a reduced-cost pixel architecture. Compared with the strip architecture and the 1Flip architecture, the trigger architecture has the characteristic of faster charging.

It should be explained that the driving system of the display panel mainly includes a data driving Circuit (COF), a Timing Controller (TCON), a gate DRIVER (GATE DRIVER) and a SOURCE DRIVER (SOURCE DRIVER). The timing controller is mainly responsible for sending control signals (namely gate line control signals, source line control signals and data signals in the scheme) for driving the display panel to the gate driver and the source driver to drive the display panel besides converting the sent LVDS differential signals into MINI-LVDS signals with low amplitude and high transmission frequency.

The gate line control signal is used for controlling the TFT opening time sequence corresponding to each row of pixel units on the display panel.

The data synchronization signal, namely the TP signal, is a data source line latch signal output to the source driving circuit by the time sequence control circuit, when the TFTs of a certain line are turned on, the source driver converts the input digital signal into an analog signal and outputs the analog signal to the source line of the TFTs, the rising edge of the TP signal latches data, and the falling edge outputs data.

The data (data) signal refers to a current required for charging the TFT.

Because the charge and discharge of the pixel units on the display panel are realized through the switch control of the gate circuit and the power input of the source line, the source line usually has the problem of signal delay, so that the charge time of the pixel units corresponding to different display areas in the display panel is not uniform, and the color cast problem of the display panel is caused. In order to solve the above technical problem, in this embodiment, the data synchronization signal outputted by the timing control circuit is rewritten to change from an original data synchronization signal to a plurality of data synchronization signals, and each data synchronization signal can be set to a different charging duration, so that the charging time of different areas of the display panel is changed under the condition that the output signal of the GOA (gate drive on array substrate) CK (clock) is unchanged, so as to improve the color shift problem caused by insufficient charging of the pixel unit.

Specifically, the open time length for controlling the source line is written in the data synchronizing signal, and the charge time length of different partitions can be controlled by limiting the open time length of the source line, so that the charge time of different areas of the display panel is changed, and the color cast problem of the pixel unit caused by insufficient charge is improved.

In some embodiments, the data synchronization signal further includes a control line number from which a target partition containing the control line number can be determined from the n partitions.

In some embodiments, the display panel further includes a plurality of scan lines parallel to each other, the scan lines extending from one end to another end opposite to the one end, and the data synchronization signal further includes a direction control signal for controlling a scanning direction of each of the scan lines on the partition.

In some embodiments, the data synchronization signal further comprises a differential signal for controlling the data signal transmission rate.

In some embodiments, a major problem caused by too large impedance difference of the fan-out area (the fan-out area is the portion where the signal line of the display area is connected to the driving chip) on the source side is that color shift occurs on both sides of the panel when displaying the color mixing picture. In the mixed-color picture, the source line charges two sub-pixels continuously, and then charges two sub-pixels of the next pixel, and the RC delay of the signal is serious due to the larger impedance of the fan-out area. Thus, the first charged subpixel is less charged than the second subpixel. Particularly where the fan-out area routing impedance is greatest, i.e. the difference in subpixel charging on both sides of the panel, will result in color shift. To solve this problem, the on-time period corresponding to the upper partition of the n partitions needs to be set to be longer than the on-time period corresponding to the lower partition.

As shown in fig. 2-5, the display panel is divided into A, B, C three partitions, the charging durations corresponding to the A, B, C three partitions are t1, t2 and t3 respectively, fig. 2 is a conventional panel charging time sequence diagram, fig. 3 is a panel charging time sequence diagram of a region a, fig. 4 is a panel charging time sequence diagram of a region B, and fig. 5 is a panel charging time sequence diagram of a region C. And taking the B area as a reference, adjusting TP signals of the A area and the C area, increasing the charging rate within the control range, wherein t1 is more than t2 and t1 is more than t3, and optimizing the color cast problem caused by insufficient charging of different areas.

Step 102, the pixel units of each partition are controlled to be turned on row by row through the gate line control signals, and meanwhile, the source line is controlled to input data signals to the turned-on pixel units for charging through the data synchronizing signals according to the corresponding charging time length so as to control the liquid crystal molecules of the pixel units to deflect at different angles, so that picture display is achieved.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein in detail.

In particular, the present application is not limited by the order of execution of the steps described, and certain steps may be performed in other orders or concurrently without conflict.

As can be seen from the above, in the display panel driving method provided by the embodiment of the present application, the gate line control signal, the source line control signal and the data signal are sent by the timing control circuit according to the preset timing, where the source line control signal includes a plurality of data synchronization signals, and the plurality of data synchronization signals respectively correspond to different partitions to adjust charging durations of the different partitions; the pixel units of each partition are controlled to be opened row by row through the grid line control signals, meanwhile, the source line is controlled to charge the data signals input to the opened pixel units through the data synchronous signals according to the corresponding charging time length, so that the liquid crystal molecules of the pixel units are controlled to deflect at different angles, and picture display is achieved. By utilizing the display panel driving method provided by the embodiment of the application, the data synchronizing signals output by the time sequence control circuit are rewritten, so that the original data synchronizing signal is converted into a plurality of data synchronizing signals, and each data synchronizing signal can be set with different charging time lengths, so that the charging time of different areas of the display panel is changed under the condition that the CK output signal of the GOA is unchanged, and the color cast problem caused by insufficient charging of the pixel units is improved.
