[0039] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0040] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0041] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0042] In a possible implementation, the display panel of the embodiment of the present disclosure may include a display driver chip, a plurality of display points, and a display component. The display driver chip may include a touch chip, which may be applied to a touch terminal; the number of display points may correspond to the resolution of the display panel; the display component may include at least one of a liquid crystal display component, a light-emitting diode display component, an organic light-emitting diode display component, and an OLED (Organic Light Emitting Diode) display component. It should be noted that the embodiment of the present disclosure does not limit the types of the display panel, the display driver chip, the display points, and the display component.

[0043] In a possible implementation, the display driving method of the embodiment of the present disclosure can be applied to a display driving chip of a display panel. For example, the display driving method of the embodiment of the present disclosure can be implemented by a dedicated hardware circuit, which can include multiple computing units, such as adders, multipliers, etc.; it can also be implemented by general processing hardware (such as a microcontroller unit (MCU), FPGA (Field Programmable Gate Array, field programmable logic device), etc.) in combination with executable logic instructions to perform the corresponding working process. The present disclosure is not limited to this.

[0044] Figure 1 The display driving method according to the embodiment of the present disclosure is shown in the flowchart. The display driving method according to the embodiment of the present disclosure can be applied to a display panel, such as Figure 1 As shown, the method includes:

[0045] Step S101, determining a first charging time length of each display point in the display panel based on a preset position of each display point in the display panel;

[0046] Step S102, generating a display control signal corresponding to each display point according to the first charging time of each display point;

[0047] Step S103: adjusting the second charging time of each display point according to the display control signal.

[0048] In one possible implementation, the first charging time may be determined based on a preset position of each display point in the display panel; the second charging time may include a charging time for display points at different positions to reach their corresponding target potentials; the first charging time may be equal to the second charging time, and the embodiments of the present disclosure do not limit the types of the first charging time and the second charging time.

[0049] In a possible implementation, in step S101, the circuit loads (e.g., resistance and capacitance loads) corresponding to display points at different positions of the display panel are inconsistent, and the first charging durations of the display points at different positions may be different. Accordingly, the charging durations for the display points at different positions of the display panel to reach their corresponding target potentials, that is, the second charging durations may also be different. It should be noted that the target potentials corresponding to each display point may be the same or different, and the embodiments of the present disclosure are not limited to this.

[0050] Figure 2 FIG. 2 shows a schematic diagram of the structure of a display panel according to an embodiment of the present disclosure. Figure 2 As shown, A, B, and C represent different display points, respectively, and D may represent an amplifier. For example, taking the circuit load as a resistor and capacitor load, the closer the distance between the display point and the display driver chip, the smaller the resistor and capacitor load corresponding to the display point, and the shorter the time required to reach the corresponding target potential; correspondingly, the farther the distance between the display point and the display driver chip, the larger the resistor and capacitor load corresponding to the display point, and the longer the time required to reach the corresponding target potential.

[0051] In a possible implementation, the larger the resistance and capacitance load of each display point, the longer the second charging time for each display point to reach its corresponding target potential may be; the smaller the resistance and capacitance load of each display point, the shorter the second charging time for each display point to reach its corresponding target potential may be. For example, taking the display points A and B in the display panel as an example, assuming that the display point A is closer to the display driver chip, the display point B is farther from the display driver chip, and the target potentials of display points A and B are the same, the second charging time for display point A to reach the target potential from 0V can be 1us, and the second charging time for display point B to reach the target potential from 0V can be 3us. It should be noted that the target potential corresponding to each display point may be different, and the resistance and capacitance loads corresponding to different display points are different, but the second charging time to reach the corresponding target potential may also be the same, and the embodiments of the present disclosure do not limit this.

[0052] Exemplarily, based on the preset position of each display point in the display panel, the first charging time of each display point can be determined according to historical data or real-time measurement. The embodiment of the present disclosure does not limit the implementation method of determining the first charging time of each display point.

[0053] By determining the first charging time of each display point by the preset position of each display point in the display panel, the output time of the display control signal corresponding to the display point can be dynamically adjusted so that each display point reaches its corresponding target potential.

[0054] In a possible implementation, in step S102, each display point has a corresponding display control signal, which may include a square wave signal. Figure 3 A schematic diagram of a display control signal according to an embodiment of the present disclosure is shown. Figure 3 T1 may represent a rising edge interval, and T2 may represent a falling edge interval. It should be noted that the embodiment of the present disclosure does not limit the specific form of the display control signal.

[0055] Each display point has a corresponding display control signal, and each display point can be accurately regulated by the display control signal to ensure the display effect of the display panel.

[0056] In a possible implementation, in step S103, when the display control signal reaches the corresponding display point, the display point starts charging, and the second charging time length of each display point can be adjusted according to the display control signal.

[0057] Exemplarily, according to the display control signal corresponding to each display point, the second charging duration of each display point can be controlled to be within the time range of the valid interval of the display control signal.

[0058] The valid interval of the display control signal includes but is not limited to the rising edge interval or the falling edge interval of the display control signal.

[0059] For example, the first charging time of each display point may be pre-set, and the embodiment of the present disclosure does not limit the setting method of the first charging time of each display point. Figure 3 As shown, T1 can represent the time range of the rising edge interval, and T2 can represent the time range of the falling edge interval. In practical applications, as the size, resolution and refresh rate of the display panel increase, the effective interval of the display control signal (the rising edge or falling edge interval of the display control signal) becomes shorter and shorter, and the display point can increase the potential within the time range of the effective interval, or reduce the potential within the time range of the effective interval.

[0060] Taking the example of the display point raising the potential within the effective interval, some display points that are far away from the display driver chip cannot reach their corresponding preset potential within the effective interval, which ultimately leads to inconsistent display effects of the entire display panel, where the preset potential can be the potential that the display point is expected to reach, and the preset potential can be the same as the target potential or different from the target potential, which is not limited in the embodiments of the present disclosure. Controlling the second charging time of each display point according to the display control signal can effectively overcome this problem, as follows:

[0061] In a possible implementation, taking the display points A, B, and C, and the time range of the effective interval as an example, assuming that the preset potentials of the display points A, B, and C are the same, all 8V, and the display point A is closest to the display driver chip, the display point B is the second closest to the display driver chip, and the display point C is the farthest from the display driver chip. The second charging time for the display point A to reach the preset potential is 1us, the second charging time for the display point B to reach the preset potential is 2us, and the second charging time for the display point C to reach the preset potential is 3us. By controlling the second charging time of each display point through the display control signal, the display point that is far away from the display driver chip cannot reach the preset potential within the time range of the effective interval, which ultimately leads to the adverse effect of inconsistent display effect of the entire display panel.

[0062] For example, since display point C is the farthest from the display driver chip, the resistance and capacitance loads are correspondingly larger, and display point C may not be able to reach the preset potential. Within the time range of the effective interval, the potential that display point C can reach can be 7.5V, while the other two display points are closer to the display driver chip and can reach the preset potential within the time range of the effective interval. In order to make the display effect of the display panel consistent, the second charging time of the other two display points can be controlled so that within the time range of the effective interval, the final potentials of display points A, B, and C are all 7.5V.

[0063] Figure 4 FIG. 1 is a schematic diagram showing the corresponding relationship between the display control signal and the potential change according to an embodiment of the present disclosure. Figure 4 As shown, when display point C receives its corresponding display control signal, display point C can be controlled to start charging at the same time; after display point B receives its corresponding display control signal, display point B can be controlled to start charging with a delay of 1us; after display point A receives its corresponding display control signal, display point A can be controlled to start charging with a delay of 2us, so as to ensure that within the time range of the effective interval, display points A, B, and C can all reach the same target potential.

[0064] In addition, the time length of the effective interval of the display control signal can also be controlled according to the second charging time length of each display point. For example, if the time required for the display point A to reach the preset potential of 8V is 1us, the time length of the effective interval of the display control signal can be changed to 0.8us, so that the final potential of the display point A is 7.5V.

[0065] Adjusting the second charging time of each display point according to the display control signal can not only improve the picture display quality of the display panel, but also effectively reduce the temperature and electromagnetic interference of the display panel.

[0066] In a possible implementation manner, determining the first charging duration of each display point includes:

[0067] Determining the distance between each display point and a display driver chip in the display panel according to the circuit configuration of the display panel;

[0068] A first charging time length of each display point is determined according to a distance between each display point and a display driving chip in the display panel.

[0069] For example, the first charging time of each display point can be determined according to the distance between each display point and the display driver chip in the display panel. The first charging time of each display point can be determined by searching historical data or by real-time measurement. The embodiment of the present disclosure does not limit the implementation method of determining the first charging time of each display point.

[0070] Taking the display points A and B in the display panel as an example, assuming that the display point A is closer to the display driver chip and the display point B is farther from the display driver chip, the first charging time of the display point A and the display point B can be determined by real-time measurement, for example, the first charging time of the display point A and the display point B can be directly measured by a meter. The embodiment of the present disclosure does not limit the implementation method of determining the first charging time of each display point.

[0071] In a possible implementation, in step S102, generating a display control signal corresponding to each display point includes:

[0072] According to the first charging time of each display point, a display control signal corresponding to each display point is generated through a preset corresponding relationship between the charging time and the display control signal.

[0073] Exemplarily, the correspondence between the charging time and the display control signal can be pre-stored in the display driver chip of the display panel, wherein the correspondence between the charging time and the display control signal can include a program code. The embodiment of the present disclosure does not limit the specific form of the correspondence between the charging time and the display control signal.

[0074] Through the correspondence between the charging time and the display control signal, as well as the first charging time of each display point, the display control signal corresponding to each display point can be quickly and accurately determined, thereby achieving accurate regulation of each display point to ensure the display effect of the display panel.

[0075] The display driving method of the embodiment of the present disclosure can determine the first charging time of each display point according to the preset position of each display point in the display panel, generate a display control signal corresponding to each display point according to the first charging time, and adjust the second charging time of each display point, so as to ensure the display consistency of the display panel; according to the display control signal, the moment when each display point reaches its corresponding target potential is controlled to be within a preset time range, which can not only improve the picture display quality of the display panel, but also effectively reduce the temperature and electromagnetic interference of the display panel.
