Referring to Figure 1, a TFT module contrast adjustment method includes:

Step S101: Acquire VOP voltage data and glass transmittance data, and generate a curve chart based on the VOP voltage data and glass transmittance data.

It should be noted that there are multiple sets of VOP voltage data and glass transmittance data, and they correspond to each other. As shown in Figure 2, Figure 2 is a graph about VOP voltage data and glass transmittance data, in which the horizontal axis is the VOP voltage data and the vertical axis is the glass transmittance data.

Step S102: Calculate the curve chart and output module display brightness data.

It should be noted that according to the curve chart, the data corresponding to the VOP voltage data and glass transmittance data on the chart are calculated, and the output module displays the brightness data. The module display brightness data here refers to the display brightness of the module, and multiple sets of module display brightness data will be generated.

Step S103: Obtain module black screen brightness data, calculate and process the output module display brightness data and module black screen brightness data, and output contrast data.

It should be noted that the module black screen brightness data refers to the brightness of the module in the black screen state. By calculating the brightness in the black screen state and the module display brightness data, the contrast data corresponding to each VOP voltage data can be obtained. .

Through the above method, the contrast of the entire display screen can be adjusted by only changing the VOP voltage data without changing the backlight brightness, which solves the problem of contrast adjustment in special scenes.

Please refer to Figure 3. Figure 3 is a more specific implementation of Figure 1, a TFT module contrast adjustment method, including:

Step S201: Acquire VOP voltage data through the first device, obtain glass transmittance data through the second device, and generate a curve chart based on the VOP voltage data and glass transmittance data.

It should be noted that the first device refers to the microcontroller baseboard, and the second device refers to the light intensity measuring instrument. The software draws a curve chart based on the data provided by the first device and the second device.

Step S202: Calculate and process the curve chart through the first algorithm according to the curve chart, and output the module display brightness data.

It should be noted that the first algorithm refers to multiplying the backlight brightness and the glass transmittance data. The backlight brightness here is unique and can be measured by a light intensity meter.

Step S203: Obtain module black screen brightness data, use the second algorithm to calculate and process the output module display brightness data and module black screen brightness data, and output contrast data.

It should be noted that the second algorithm here refers to dividing the module display brightness data by the module black screen brightness data, and their quotient is the contrast data.

Further, in another embodiment, a TFT module contrast adjustment method includes:

S104. Obtain the ambient brightness data, analyze and process the ambient brightness data and module display brightness data, output real-time contrast data, and use the real-time contrast data as contrast data.

It should be noted that in special scenes, due to different light intensities and even direct strong light, the contrast needs to be adjusted to achieve the best display effect. The software will obtain the ambient brightness data in real time, analyze and calculate the acquired ambient brightness data and the module display brightness data, then input an optimal VOP voltage, and calculate the real-time contrast data to achieve the best contrast.

Further, in another embodiment, a TFT module contrast adjustment method includes:

S105. Generate energy-saving instructions according to the preset time threshold;

S106. Execute the energy-saving instruction, and output energy-saving contrast data as contrast data through the first algorithm and the second algorithm according to the curve chart.

It should be noted that in order to prevent high power consumption and meet the requirements of energy conservation and emission reduction, this application sets a time threshold, generally 30 minutes. When 30 minutes is reached, an energy-saving instruction will be generated, and the most energy-saving contrast data corresponding to the current VOP voltage will be calculated based on the curve chart to achieve the purpose of energy saving.
