[0001] The present invention belongs to the technical field of displays, and particularly relates to a method, device, equipment, medium and display for adjusting display effects. Background Art

[0002] According to the display principle of LCD displays, the light source of the LCD display screen comes from a backlight module using LED light bars. The liquid crystal panel covers the backlight, and the display control circuit board outputs various voltage signals to the liquid crystal panel to control the light transmission time, frequency, deflection angle, etc. of the liquid crystal, so that the LCD display can present various display screens with different brightness levels.

[0003] For displays that use voltage modulation waves to adjust the backlight intensity, there are the following defects. When the voltage modulation waveform is at a high level, the backlight is in a bright state. It is observed that the charging efficiency of the liquid crystal is low at this time, and the low charging efficiency of the liquid crystal will cause the brightness of the display screen controlled by the display control circuit board to be relatively low, and the display screen brightness is relatively low at this time; when the voltage modulation waveform is at a low level, the backlight is in a non-bright state. It is observed that the charging efficiency of the liquid crystal is higher at this time compared to the bright state of the backlight, and the display screen brightness is relatively high at this time. Due to the above phenomena, the difference in the high and low levels of the voltage modulation wave causes the same picture with the same brightness to be inconsistent in brightness and darkness, affecting the display effect.

The terms used herein are for the purpose of describing embodiments of this application only and are not intended to limit this application.

[0026] Embodiment 1:

[0027] In view of the problems existing in the prior art, such as Figure 1 As shown, this application provides a method for adjusting display effects. The method is applied to an electronic device, which can be a server, a mobile terminal, a computer, a cloud platform, a display, etc. The functions implemented by the device data processing in the embodiments of this application can be realized by a processor of the electronic device calling program code. Among them, the program code can be stored in a computer storage medium. The method for adjusting the display effect includes:

[0028] Step S1: Obtain the current level state of the backlight drive voltage pulse width modulation wave in the display.

[0029] At present, the method for adjusting the overall brightness of the display screen of an LCD display is to control the average brightness of the light bar within a period of time. The backlight drive voltage pulse width modulation wave can be used to adjust the overall brightness of the LED light bar within a period of time. This method uses a device that controls the high and low levels of the PWM wave to achieve the purpose. When the backlight drive voltage pulse width modulation wave is at a high level, the LED light bar is in the lit state. When the backlight drive voltage pulse width modulation wave is at a low level, the LED light bar is in the off state. Let the high-level time of the backlight drive voltage pulse width modulation wave within a period of time (t) be x, and the low-level time of the voltage modulation wave within a period of time t be (t - x). Let the brightness of the LED light bar at a high level be y, and the brightness of the LED light bar at a low level be z. Then the average brightness of the LED light bar within a period of time (t) = yx + z(1 - x). Through such a relationship, the average brightness of the LED light bar within a period of time (t) can be controlled to achieve the brightness adjustment function of the LCD display. However, since the backlight is in a lit state when the voltage modulation waveform is at a high level, it is observed that the charging efficiency of the liquid crystal is low at this time, and the low charging efficiency of the liquid crystal will cause the brightness of the display screen controlled by the display control circuit board to be relatively low. At this time, the brightness of the display screen is relatively low; when the voltage modulation waveform is at a low level, the backlight is in an unlit state, and it is observed that the charging efficiency of the liquid crystal is higher than that in the state where the backlight is lit at this time. At this time, the brightness of the display screen is relatively high. Due to the above phenomena, the difference in the high and low levels of the voltage modulation wave makes the same picture with the same brightness bright and dark inconsistent, affecting the display effect.

[0030] Therefore, in the present application, to solve this technical problem, it is necessary to adjust the display effect of the display according to the level state of the backlight drive voltage pulse width modulation wave. Therefore, in the present application, it is necessary to obtain the current level state of the backlight drive voltage pulse width modulation wave. The level state includes: high level and low level.

[0031] Step S2: Obtain the current grayscale data of the display.

[0032] In the display principle of an LCD display, the liquid crystal in the display is driven by the TFT array. The TFT array can output an on-state voltage, and the on-state voltage will affect the deflection angle of the liquid crystal and the charging rate of the liquid crystal. When the on-state voltage is the same, the grayscale data controls the display result of the liquid crystal image, and different grayscale data gives different charging times to the liquid crystal. Therefore, in the present application, it is also necessary to obtain the current grayscale data of the display.

[0033] Step S3: Determine the target on-state voltage of the TFT array according to the current level state and the current grayscale data.

[0034] Since the purpose of the present application is to make the brightness of the final displayed image of the display not affected by the backlight brightness. Therefore, it is necessary to determine the target on-state voltage of the TFT array according to the current level state and the current grayscale data.

[0035] In some embodiments, step S3 "determine the target on-state voltage of the TFT array according to the current level state and the current grayscale data" includes:

[0036] Step S31: Obtain the target modulation table of the display.

[0037] There is a target modulation table in the display. The target modulation table is determined during the development and testing stage. During the development and testing stage, a set of optimal on-state voltages of the TFT switches under the joint influence of the current performance of the display and the level state of the backlight drive pulse width modulation wave are obtained according to the current performance of the display and the chips installed in the display.

[0038] Therefore, in some embodiments, the target modulation table includes: current grayscale data, serial number, on-state voltage, and current level condition. The current grayscale data has a corresponding relationship with the serial number. Each serial number corresponds to at least two on-state voltages. Each on-state voltage corresponds to one current level state.

[0039] Among them, the grayscale data is divided into multiple ranges according to a preset rule, each grayscale data range corresponds to a serial number, and each serial number corresponds to two target on-state voltages. And behind each on-state voltage, there corresponds a current level state. For example, the grayscale data from 0 to 50 is divided into the grayscale data range of serial number 1, and serial number 1 corresponds to two target on-state voltages. Suppose these two target on-state voltages are 1-1 and 1-2 respectively. And the current level state corresponding to the 1-1 target on-state voltage is high level, and the current level corresponding to the 1-2 target on-state voltage is low level. Specifically, as Figure 2 shown.

[0040] However, the performance of some displays can be changed. The performance of the display includes: current resolution and current power. Therefore, in some embodiments, step S31 "obtain the target modulation table of the display" includes:

[0041] Step S311: Obtain the current resolution of the display.

[0042] Step S312: Obtain the current power of the display.

[0043] Step S313: Determine the target modulation table according to the current power and the current resolution.

[0044] Since the optimal TFT on-state voltage of the display is different under different performances, different performances of the display correspond to different modulation tables. And the main performances of the display are current resolution and current power. Therefore, in this application, it is necessary to obtain the current resolution and current power. And there are multiple modulation tables in the database of the display or the online database, and these modulation tables correspond to different display performances. Therefore, in this application, it is necessary to determine the corresponding target modulation table according to the current resolution and current power of the display.

[0045] Therefore, in some embodiments, the modulation table further includes the correspondence with the current resolution and the current power of the reality. That is, the unique target modulation table can be determined through the current resolution and the current power.

[0046] Step S32: Determine the target on-state voltage in the target modulation table according to the current grayscale data and the current level state.

[0047] Since there is the target on-state voltage of the optimal TFT switch under the joint influence of the grayscale data and the level state of the backlight drive pulse width modulation wave in the target modulation table. Therefore, in this application, the corresponding target on-state voltage can be determined in the target modulation table according to the current grayscale data and the current level state.

[0048] Since there are many corresponding relationships in the target modulation table, in some embodiments, step S32, "determine the target on-state voltage in the target modulation table according to the current grayscale data and the current level state", includes:

[0049] Step S321: Determine the serial number from the target modulation table according to the current grayscale data.

[0050] Step S322: Determine the target on-state voltage in the target modulation table according to the serial number and the current level.

[0051] Since the grayscale data is divided into ranges in the target modulation table, after obtaining the current grayscale data, the range of the current grayscale data can be determined. Different ranges of grayscale data correspond to different serial numbers, so the serial number where the target on-state voltage is located can be determined according to the current grayscale data. Since there are at least two target on-state voltages in each serial number, after determining the serial number where the target on-state voltage is located, it is also necessary to determine which on-state voltage in this serial number is the current best target on-state voltage according to the current level situation.

[0052] Step S4: Adjust the display effect of the display according to the target on-state voltage.

[0053] After determining the target on-state voltage, the target on-state voltage can be connected to the G pole of the TFT switch to change the opening rate of the TFT switch, and then affect the charging rate of the liquid crystal by changing the opening rate of the TFT switch, and further affect the final display effect of the display. Finally, it enables the display to maintain a consistent display screen brightness under different backlight voltages, improving the display effect of the display. It improves the defects brought by the pulse width modulation of the backlight drive voltage of the LCD display.
