Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

Example 1:

in view of the problems in the prior art, as shown in fig. 1, the present application provides a method for adjusting a display effect, where the method is applied to an electronic device, and the electronic device may be a server, a mobile terminal, a computer, a cloud platform, a display, and the like. The function realized by the device data processing provided by the embodiment of the application can be realized by calling a program code by a processor of the electronic device, wherein the program code can be stored in a computer storage medium, and the method for adjusting the display effect comprises the following steps:

step S1: and acquiring the current level state of a backlight driving voltage pulse width modulation wave in the display.

At present, the method for adjusting the overall brightness of the display frame by the LCD display is to control the average brightness of the light bar within a period of time. The method includes that a device for controlling the high level and the low level of a PWM wave is used for achieving the purpose, when the backlight driving voltage PWM wave is at the high level, the LED light bar is in a lighting state, when the backlight driving voltage PWM wave is at the low level, the LED light bar is in a blanking state, the high level time of the backlight driving voltage PWM wave in a period of time (t) is set to be x, the D low level time of the voltage modulation wave in the period of time t is set to be (t-x), the brightness of the LED light bar at the high level is set to be y, the brightness of the LED light bar at the low level is set to be z, and the average brightness of the LED light bar in the period of time (t) is = yx + z (1-x). Through the relation, the average brightness of the LED lamp bars in a period of time (t) can be controlled, and the brightness adjusting function of the LCD display is realized. However, when the voltage modulation waveform is at a high level, the backlight is in a bright state, and the observation shows that the charging efficiency of the liquid crystal is low, and the low charging efficiency of the liquid crystal can cause the brightness of the display picture controlled by the display control circuit board to be relatively low, and the brightness of the display picture is relatively low; when the voltage modulation waveform is at a low level, the backlight is in a non-bright state, and the charging efficiency of the liquid crystal is observed to be higher than that of the backlight in a bright state, and the brightness of the display screen is relatively higher. Due to the above phenomenon, the different levels of the voltage modulation wave make the same image with the same brightness inconsistent in brightness, which affects the display effect.

Therefore, in order to solve the technical problem in the present application, the display effect of the display needs to be adjusted according to the level state of the backlight driving voltage pwm wave. It is necessary in this application to acquire the current level state of the backlight driving voltage pulse width modulated wave. The level states include: high and low.

Step S2: and acquiring current gray scale data of the display.

In the display principle of LCD displays, the liquid crystal in the display is driven by an array of TFTs. The TFT array may output an on-voltage that affects the angle of deflection of the liquid crystal and the rate of charging of the liquid crystal. Under the condition of the same on-state voltage, the gray scale data controls the picture display result of the liquid crystal, and the charging time of different gray scale data to the liquid crystal is different. There is also a need in the present application to obtain current gray scale data for the display.

And step S3: and determining the target on-state voltage of the TFT array according to the current level state and the current gray scale data.

The purpose of the present application is to make the brightness of the final display frame of the display not affected by the brightness of the backlight. It is necessary to determine the target on-state voltage of the TFT array based on the current level state and the current gray scale data.

In some embodiments, the step S3 "determining a target on-state voltage of the TFT array according to the current level state and the current gray scale data" includes:

step S31: and acquiring a target modulation table of the display.

A target modulation table is present in the display. The target modulation table is determined during a development test phase. And in the development and test stage, the target on-state voltage of the optimal TFT switch under the joint influence of a group of gray scale data and the level state of a backlight driving pulse width modulation wave can be obtained according to the current performance of the display and multiple chips carried in the display.

So in some embodiments, the target modulation table comprises: current gray scale data, sequence number, on voltage, and current level condition. The current gray scale data and the serial number are in corresponding relation. Each serial number corresponds to at least two of the on-state voltages. Each of the on-state voltages corresponds to one of the current level states.

The gray scale data is divided into a plurality of ranges according to a preset rule, each gray scale data range corresponds to one serial number, and each serial number corresponds to two target on-state voltages. Each of which is followed by a current level state. For example, 0-50 of the gray scale data is divided into the gray scale data range of No. 1, and the No. 1 corresponds to two target on-state voltages, which are assumed to be 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. As shown in detail in fig. 2.

But the performance of some displays may vary. Wherein the performance of the display comprises: current resolution and current power. Therefore, in some embodiments, the step S31 "acquiring the target modulation table of the display" includes:

step S311: a current resolution of the display is obtained.

Step S312: obtaining a current power of the display.

Step S313: and determining the target modulation table according to the current power and the current resolution.

Because the optimal TFT on-state voltage of the display under different performances is different, the different performances of the display correspond to different modulation tables. While the main performance of the display is the current resolution and the current power. The current resolution and current power need to be obtained in this application. There are a plurality of modulation tables in the display database or in-line database, which correspond to different display capabilities. It is necessary in this application to determine the corresponding target modulation bar based on the current resolution and current power of the display.

In some embodiments, the modulation table further includes a corresponding relationship between the current resolution and the current power. I.e. a unique target modulation table can be determined by the current resolution and the current power.

Step S32: and determining a target on-state voltage in the target modulation table according to the current gray scale data and the current level state.

The target modulation table has the target on-state voltage of the optimal TFT switch under the joint influence of the gray scale data and the level state of the backlight driving pulse width modulation wave. Therefore, in the present application, the corresponding target on-state voltage can be determined in the target modulation table according to the current gray scale data and the current level state.

However, there are many corresponding relationships in the target modulation table. Therefore, in some embodiments, the step S32 "determining a target on-state voltage in the target modulation table according to the current gray-scale data and the current level state" includes:

step S321: and determining the sequence number from the target modulation table according to the current gray scale data.

Step S322: and determining the target on-state voltage in the target modulation table according to the sequence number and the current level.

Since the gray scale data is subjected to range division in the target modulation table, after the current gray scale data is obtained, the range of the current gray scale data can be determined, and the ranges of different gray scale data correspond to different serial numbers, so that the serial number of the target on-state voltage can be determined according to the current gray scale data. Since there are at least two target on-state voltages in each sequence number, after the sequence number where the target on-state voltage is located is determined, it is further required to determine which on-state voltage in the sequence number is the currently optimal target on-state voltage according to the current level condition.

And step S4: and adjusting the display effect of the display according to the target on-state voltage.

After the target on-state voltage is determined, the target on-state voltage can be connected to the G pole of the TFT switch, the opening rate of the TFT switch is changed, the charging rate of the liquid crystal is influenced by changing the opening rate of the TFT switch, and the display effect of the final display is influenced. Finally, the display can still ensure the brightness of the display picture under the condition of different backlight voltages, and the display effect of the display is improved. The defects caused by the pulse width modulation of the backlight driving voltage of the LCD display are improved.
