[0002] At present, in the display control of a display panel, a display driving chip usually sends a lock signal to indicate that the display driving chip and a timing controller are frequency-locked, but when the display driving chip triggers an unlock signal, the timing controller directly re-sends a calibration code to realize reconnection with the display driving chip. The direct sending of the unlock signal in the related technology causes flickering of the display panel, affecting the user experience. SUMMARY

[0003] Therefore, the present disclosure provides a display control method, which is applied to a timing controller of a display, and the timing controller comprises a signal transmitter. The method comprises the following steps.

[0004] When a level state of a lock signal sent by a display driving chip changes from a first state to a second state, a maintaining duration of the second state of the lock signal is determined, and the lock signal is used to control a communication link between the display driving chip and the timing controller.

[0005] If the maintaining duration exceeds a first preset duration, a voltage swing of a data signal sent by the signal transmitter is increased.

[0006] In a possible implementation, the method further comprises the following steps.

[0007] If the maintaining duration exceeds a second preset duration, the sending of the data signal is interrupted, and a calibration code is sent, the calibration code being used to restore connection of the communication link between the display driving chip and the timing controller, and the second preset duration being greater than the first preset duration.

[0008] In a possible implementation, the method further comprises the following steps.

[0009] When the calibration code is sent, a voltage swing of the calibration code sent by the signal transmitter is increased.

[0010] In a possible implementation, the first preset duration is 1 μs, and the second preset duration is 5 μs.

[0011] In a possible implementation, the increased voltage swing is 2-5 times of an initial voltage swing.

[0012] In a possible implementation, the method further comprises at least one of the following.

[0013] If the duration of maintenance is less than or equal to the first preset duration, then the data signal is transmitted normally.

[0014] When the locking signal switches from the second state to the first state, the voltage swing of the data signal transmitted by the signal transmitter is increased.

[0015] In one possible implementation, the first state is high and the second state is low.

[0016] According to another aspect of this disclosure, a timing controller for a display is provided, the timing controller including a signal transmitter, the timing controller comprising:

[0017] The first determining module is used to determine the duration of the second state of the locking signal when the level state of the locking signal sent by the display driver chip changes from the first state to the second state. The locking signal is used to control the communication link between the display driver chip and the timing controller.

[0018] The power adjustment module is used to: increase the voltage swing of the data signal transmitted by the signal transmitter if the duration of maintenance exceeds a first preset duration.

[0019] According to another aspect of this disclosure, a display driver chip is provided, the display driver chip including a timing controller for the display.

[0020] According to another aspect of this disclosure, a display is provided, the display comprising:

[0021] The display driver chip;

[0022] Display panel.

[0024] According to one aspect of this disclosure, an electronic device is provided, the electronic device including the aforementioned display.

[0025] The timing controller of this embodiment determines the duration of the second state of the lock signal when the level state of the lock signal sent by the display driver chip changes from a first state to a second state. If the duration exceeds a first preset duration, the voltage swing of the data signal sent by the signal transmitter is increased to improve the transmission quality of the data signal. This avoids screen flickering caused by retransmission of the unlock signal due to the state change of the lock signal caused by interference, thereby improving display quality and user experience.

[0034] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0035] As used herein, the terms “comprising,” “including,” “having,” or variations thereof are open-ended and include one or more of the stated features, integrals, elements, steps, components, or functions, but do not exclude the presence or addition of one or more other features, integrals, elements, steps, components, functions, or groups thereof.

[0036] When an element is referred to as “connected,” “coupled,” “responding,” or a variation thereof relative to another element, it may be directly connected, coupled, or responding to another element, or there may be an intermediate element present.

[0037] Although the terms first, second, third, etc., may be used herein to describe various elements / operations, these elements / operations should not be limited by these terms. These terms are only used to distinguish one element / operation from another. Therefore, without departing from the teachings of the inventive concept, a first element / operation in some embodiments may be referred to as a second element / operation in other embodiments.

[0038] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0039] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0040] In view of the deficiencies mentioned in the background art, this disclosure proposes a timing controller that, when the level state of a lock signal received from a display driver chip changes from a first state to a second state, determines the duration of the second state of the lock signal. If the duration exceeds a first preset duration, the voltage swing of the data signal transmitted by the signal transmitter is increased, thereby improving the transmission quality of the data signal. This avoids screen flickering caused by retransmission of the unlock signal due to a change in the state of the lock signal caused by interference, thereby improving display quality and user experience.

[0041] The embodiments disclosed herein do not limit the specific implementation of the timing controller and the display driver chip; those skilled in the art can set them according to actual conditions and needs.

[0042] For example, the timing controller TCON is located between the image source and the driver chip. It can receive host image data and convert it into a format compatible with the panel driver chip (such as LVDS to miniLVDS / RSDS). It can generate control signals such as horizontal synchronization (HSync), vertical synchronization (VSync), and data enable (DE). It can perform image quality enhancement functions such as gamma correction, frame rate conversion (FRC), and data scrambling. The specific functions of the timing controller TCON are not limited in this disclosure. Those skilled in the art can implement it according to the actual situation and needs, referring to relevant technologies.

[0043] For example, the timing controller TCON can be implemented using a processing component. In some possible implementations, the processing component includes, but is not limited to, a separate processor, discrete components, or a combination of a processor and discrete components. The processor can include a controller in an electronic device with instruction execution capabilities. The processor can be implemented in any suitable manner, for example, by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components. Within the processor, the executable instructions can be executed using hardware circuitry such as logic gates, switches, ASICs, programmable logic controllers, and embedded microcontrollers.

[0044] Preferably, the timing controller TCON may include a dedicated ASIC chip, or the TCON function may be implemented through a hardware description language (Verilog / VHDL).

[0045] For example, the timing controller TCON may include an input interface module that receives LVDS / MIPI / HDMI signals from the host, performs level conversion and data recovery, and may have a built-in CDR (clock data recovery) circuit to extract the clock from the serial data stream; a core control module that may include a timing generator (generating a precise pixel clock based on a PLL to drive row and column counters to generate synchronization signals), a state machine (coordinating the workflow of each stage to ensure strict synchronization between data and control signals), and a data processing unit (performing gamma correction, color space conversion, and data bit width adjustment); an output interface module that generates differential signals (such as mini LVDS / RSDS) and control signals required by the display driver chip; a power management circuit that can provide various voltages (VGH / VGL / AVDD / DVDD / Vcom) through DC-DC conversion; and a gamma correction circuit that can generate a 256-level grayscale voltage reference to compensate for the nonlinear characteristics of the liquid crystal, etc.

[0046] This disclosure does not limit the type or implementation method of the display driver chip. Those skilled in the art can refer to relevant technologies to implement it according to actual conditions and needs. For example, the display driver chip can be adapted to the type of display panel, such as LCD driver chips, LED / OLED driver chips, MicroLED driver chips, etc.

[0047] For example, a display driver chip may include a gate driver, a source driver, etc.

[0048] For example, the timing controller TCON and the source driver in the display driver chip can be implemented based on the P2P (Point-to-Point) protocol. For details on the P2P protocol, please refer to the relevant technical documentation.

[0049] Please see Figure 1 , Figure 1 A flowchart of a display control method according to an embodiment of the present disclosure is shown.

[0050] The method is applied to the timing controller (TCON) of the display, the timing controller including a signal transmitter, such as... Figure 1 As shown, the method includes:

[0051] Step S11: When the level state of the lock signal sent by the display driver chip (DDIC) changes from the first state to the second state, determine the duration of the second state of the lock signal. The lock signal is used to control the communication link between the display driver chip and the timing controller.

[0052] Step S12: If the duration exceeds the first preset duration, increase the voltage swing of the data signal transmitted by the signal transmitter.

[0053] The embodiments disclosed herein do not limit the type of level state of the lock signal. Those skilled in the art can set it according to actual conditions and needs. For example, the first state can be a high level and the second state can be a low level.

[0054] The embodiments disclosed herein do not limit the specific size of the increased voltage swing. Those skilled in the art can set it according to actual conditions and needs. For example, in one possible implementation, the increased voltage swing is 2 to 5 times the initial voltage swing.

[0055] For example, if the initial voltage swing is 200~300mV, the voltage swing of the data signal transmitted by the signal transmitter is increased to more than 600mV after a first preset duration. For example, the maximum voltage swing can reach 1V.

[0056] The duration of this embodiment can be adjusted between the first preset duration and the second preset duration to activate the operation of increasing the voltage swing of the transmitted data signal.

[0057] The embodiments disclosed herein do not limit the specific values ​​of the first preset duration and the second preset duration. Those skilled in the art can set them according to actual circumstances and needs. For example, in one possible implementation, the first preset duration is 1 μs and the second preset duration is 5 μs. Of course, the first preset duration can also be a value around 1 μs (e.g., ±0.3 μs), and the second preset duration can also be a value around 5 μs (e.g., ±0.3 μs). The embodiments disclosed herein do not limit this.

[0058] In this embodiment of the disclosure, by setting the first preset duration to 1μs (or a value near 1μs) and the second preset duration to 5μs (or a value near 5μs), if the lock signal is restored within 1μs to 5μs, abnormal screen flickering can be avoided.

[0059] It should be understood that, in one example, the timing of restoring the lock signal (the lock signal switching from low to high) may be at any time between the first preset duration and the second preset duration, for example, 4 μs. Even if the lock signal is restored at 4 μs, embodiments of this disclosure may increase the data signal quality by increasing the voltage swing until a certain time when the duration exceeds the second preset duration.

[0060] Of course, the specific implementation method of the display driver chip restoring the state of the lock signal is not limited in the embodiments of this disclosure. For example, the display driver chip can directly restore the lock signal when it can continuously obtain accurate data signals (such as when the error rate of the data signal is lower than the threshold). Of course, other methods are also possible. Those skilled in the art can refer to relevant technologies to implement it according to actual conditions and needs.

[0061] For example, when the level of the locking signal is in the first state, the communication link between the display driver chip and the display timing controller is in the connected state. The display driver chip locks the clock signal of the timing controller, and the display driver chip can lock the data signal of the timing controller. Therefore, the display data can be accurately obtained.

[0062] When the level of the locking signal is in the second state, the communication link between the display driver chip and the display timing controller is in the unlock state, which can also be called the unlocked state. In this state, the display driver chip cannot lock the data signal of the timing controller.

[0063] In related technologies, when the timing controller detects that the lock signal has switched from the first state to the second state, it immediately sends a training code to relock the clock with the display driver chip. However, during the relocking process of retransmitting the training code, because the logic of the display driver chip is to "pause normal display and prioritize link calibration," the display driver chip will force the sout output to enter one of two abnormal states: high impedance (Hiz) or short to GND. In the high impedance state, the sout pin of the display driver chip is disconnected from the pixel electrode, and the voltage on the pixel electrode that originally maintained the brightness will rapidly dissipate, causing the pixel to change from normal brightness to "no voltage state" (grayscale jumps / turns black). In the short to GND state, the sout pin is directly grounded, and the pixel electrode is forced to 0 potential, resulting in the corresponding pixel being instantly completely black. When the display driver chip completes the relock, sout will restore the normal voltage output, and the pixel will return from "abnormal black / grayscale jumps" to normal brightness.

[0064] Therefore, retransmitting the training code triggers the relocking of the display driver chip's link. During the relocking transition (Unlock), the core signal (sout) output by the display driver chip to the panel loses its normal voltage, causing the pixel brightness to be abnormal for a moment. When the relocking is completed, the output returns to normal. This rapid switch from abnormal to normal will manifest as screen flickering.

[0065] This embodiment detects the state switching duration of the lock signal. If the duration exceeds a first preset duration, the voltage swing of the data signal transmitted by the signal transmitter is increased. This improves the transmission quality of the data signal, allowing the display chip to receive high-quality display data. Therefore, the cause of the current signal anomaly can be considered to be real-time interference (including radio frequency interference). In this case, the display driver chip can switch the lock signal from the second state back to the first state, and the timing controller can avoid sending a training code, thereby preventing screen flickering.

[0066] The embodiments disclosed herein do not limit the specific implementation of the detection of the level state and duration of the lock signal. Those skilled in the art can adopt appropriate technical solutions according to actual conditions and needs. For example, it may include a level comparator, a timer and its peripheral circuits. The lock signal is determined by comparing the current level state of the lock signal with a preset level (such as any value between half the level value of the first state and the level value of the first state) through the level comparator. When the comparison state of the comparator deflects, the timer can start timing to determine the duration of the lock signal.

[0067] Please seeFigure 2 , Figure 2 A flowchart of a display control method according to an embodiment of the present disclosure is shown.

[0068] In one possible implementation, such as Figure 2 As shown, the method further includes:

[0069] Step S13: If the duration of maintenance exceeds the second preset duration, the transmission of data signals is interrupted and a calibration code is transmitted. The calibration code is used to restore the communication link between the display driver chip and the timing controller. The second preset duration is longer than the first preset duration.

[0070] If the duration exceeds the second preset duration, the screen may flicker even if the voltage swing of the data signal is increased, as the locked state cannot be restored. Therefore, a calibration code needs to be sent to restore the lock.

[0071] This disclosure does not limit the specific calibration code. Those skilled in the art can set it according to the actual situation and needs, referring to the P2P protocol. As an example, the calibration code can be 100001111.

[0072] For example, after transmitting one or more sets of calibration codes, the display driver chip and timing controller can relock.

[0073] In one possible implementation, such as Figure 2 As shown, the method may further include:

[0074] Step S14: When sending the calibration code, increase the voltage swing of the calibration code sent by the signal transmitter.

[0075] By increasing the voltage swing of the calibration code transmitted by the signal transmitter, embodiments of this disclosure can improve the efficiency of lock recovery.

[0076] For example, in embodiments of this disclosure, the voltage swing of the calibration code sent by the signal transmitter until the lock signal completes the state switch can be increased, or the time can be extended as needed. This disclosure does not limit the scope of the embodiments.

[0077] The embodiments disclosed herein do not limit the specific size of the voltage swing that increases the transmission of the calibration code. Those skilled in the art can set it according to actual conditions and needs. For example, in one possible implementation, the increased voltage swing is 2 to 5 times the initial voltage swing.

[0078] For example, if the initial voltage swing is 200~300mV, the voltage swing of the data signal transmitted by the signal transmitter is increased to more than 600mV after a first preset duration. For example, the maximum voltage swing can reach 1V.

[0079] In one possible implementation, such as Figure 2 As shown, the method may further include at least one of the following:

[0080] Step S15: After the locking signal switches from the second state to the first state, increase the voltage swing of the data signal transmitted by the signal transmitter;

[0081] Step S16: If the duration of maintenance is less than or equal to the first preset duration, then the data signal is sent normally.

[0082] For example, if the duration of maintenance is less than or equal to the first preset duration, it can be considered a normal lock. Therefore, fluctuations in the lock signal are ignored, and data signals are transmitted normally.

[0083] For example, when the locking signal switches from the second state to the first state, the voltage swing of the data signal transmitted by the signal transmitter can be increased as needed, thereby improving the quality of signal transmission and preventing the display driver chip and timing controller from losing their lock due to sudden signal interference.

[0084] Of course, those skilled in the art can set the specific timing for increasing the voltage swing according to actual conditions and needs. It can be increased periodically or after the interference intensity value of the acquired radio frequency signal reaches a preset value. This disclosure does not limit the specific period size or the specific method for determining the radio frequency signal interference intensity; those skilled in the art can refer to relevant technologies to implement it according to actual conditions and needs.

[0085] The various signals of the embodiments of this disclosure are described below with reference to specific waveform diagrams.

[0086] In the waveform diagrams below, LOCK represents the lockout signal, DLM Error represents the DataLink Monitor Error, and Data represents the transmitted data (including RGB signal data and calibration code CT).

[0087] Please see Figure 3 , Figure 3 A waveform diagram is shown when the duration of maintenance is less than the first preset duration.

[0088] For example, such as Figure 3 As shown, if the duration T1 is less than or equal to the first preset duration (1μs), the data signal is transmitted normally.

[0089] Please see Figure 4 , Figure 4 The diagram shows a waveform when the duration is between a first preset duration and a second preset duration.

[0090] For example, such as Figure 4 As shown, if the duration exceeds the first preset duration, the voltage swing of the data signal transmitted by the signal transmitter is increased until the timing duration reaches the second preset duration.

[0091] For example, such as Figure 4 As shown, since the duration T1 exceeds the first preset duration, this embodiment of the present disclosure increases the voltage swing of the transmitted data signal until the timing duration reaches the second preset duration.

[0092] For example, such as Figure 4 As shown, when the locking signal switches from the second state to the first state, this embodiment of the present disclosure can still increase the voltage swing of the data signal transmitted by the signal transmitter to improve signal quality.

[0093] Please see Figure 5 , Figure 5 A waveform diagram is shown when the duration exceeds the second preset duration.

[0094] For example, such as Figure 5 As shown, the duration T1 exceeds the second preset duration. Therefore, in this embodiment of the present disclosure, the transmission of data signals is interrupted starting from the second preset duration, and a calibration code is transmitted to restore the connection of the communication link between the display driver chip and the timing controller.

[0095] For example, such as Figure 5 As shown, when the locking signal switches from the second state to the first state, this embodiment of the present disclosure can still increase the voltage swing of the data signal transmitted by the signal transmitter to improve signal quality.

[0096] It should be understood that, Figure 3 , Figure 4 , Figure 5 Although the data link monitoring error rate represented by N and M for DLM Error has been introduced, and the descriptions of normal TX (representing normal voltage swing) and large swing (representing increased voltage swing) in the various figures are exemplary descriptions, these identification information should not be regarded as a limitation on the embodiments of this disclosure.

[0097] Please see Figure 6 , Figure 6 A schematic diagram of a timing controller for a display according to an embodiment of the present disclosure is shown.

[0098] like Figure 6 As shown, the timing controller includes a signal transmitter, and the timing controller further includes:

[0099] The first determining module 10 is used to determine the duration of the second state of the locking signal when the level state of the locking signal sent by the display driver chip changes from the first state to the second state. The locking signal is used to control the communication link between the display driver chip and the timing controller.

[0100] The power adjustment module 20 is used to: increase the voltage swing of the data signal transmitted by the signal transmitter if the duration of maintenance exceeds the first preset duration.

[0101] The timing controller of this embodiment determines the duration of the second state of the lock signal when the level state of the lock signal sent by the display driver chip changes from a first state to a second state. If the duration exceeds a first preset duration, the voltage swing of the data signal sent by the signal transmitter is increased to improve the transmission quality of the data signal. This avoids screen flickering caused by retransmission of the unlock signal due to the state change of the lock signal caused by interference, thereby improving display quality and user experience.

[0102] In one possible implementation, the timing controller further includes:

[0103] The transmitting module is configured to: interrupt the transmission of data signals and transmit a calibration code if the duration of maintenance exceeds a second preset duration, wherein the calibration code is used to restore the communication link between the display driver chip and the timing controller, and the second preset duration is longer than the first preset duration.

[0104] In one possible implementation, the power adjustment module is further configured to include:

[0105] When the calibration code is sent, the voltage swing of the calibration code sent by the signal transmitter is increased.

[0106] In one possible implementation, the first preset duration is 1 μs and the second preset duration is 5 μs.

[0107] In one possible implementation, the increased voltage swing is 2 to 5 times the initial voltage swing.

[0108] In one possible implementation, the timing controller is further configured to perform at least one of the following:

[0109] If the duration of maintenance is less than or equal to the first preset duration, then the data signal is transmitted normally.

[0110] When the locking signal switches from the second state to the first state, the voltage swing of the data signal transmitted by the signal transmitter is increased.

[0111] In one possible implementation, the first state is high and the second state is low.

[0112] It should be understood that the timing controller is the same as the aforementioned method, and its specific description can be found in the previous description of the method, which will not be repeated here.

[0113] According to another aspect of this disclosure, a display driver chip is provided, including the aforementioned timing controller.
