Referring to FIG. 4, FIG. 4 is a first embodiment of the image generation method of the present invention, the image generation method is applied to the above-mentioned display panel assembly, and the steps of the image generation method include the following steps:

Step S10, when receiving the shooting instruction, start the photosensitive element, so that the photosensitive surface of the photosensitive element receives the primary color light decomposed by the color filter;

In the present invention, the display panel assembly is a part of the mobile terminal, and this embodiment is described with the mobile terminal as the execution subject.

When the mobile terminal does not enable the shooting function, the photosensitive element is in a closed state, so as to reduce power consumption of the mobile terminal. When the mobile terminal receives the shooting instruction, the mobile terminal switches the current interface to the shooting interface. At this time, the mobile terminal activates the photosensitive element, and the light enters from the display screen of the mobile terminal (the glass substrate in the display panel assembly), and then passes through the color screen. The filter is decomposed into the corresponding primary color light, and the primary color light is received by the photosensitive surface of the photosensitive element (because the photosensitive surface of the photosensitive element is not provided with a filter, it will not appear that the primary color light is not received by the photosensitive surface of the photosensitive element ).

The mobile terminal Pulse signals can be generated from grayscale values.

The spatial color mixing method is to make use of the poor spatial detail resolution of the human eye to bring the corresponding positions of the three primary color lights on the same plane close enough to each other. , you will feel the color of the three primary color lights mixed.

Step S60, determining the thin film transistor corresponding to the pulse signal;

Pixels have corresponding display positions on the display panel (glass substrate) of the mobile terminal, and each display position has a corresponding thin film transistor. Since the mobile terminal uses the spatial color mixing method to display images, the display position corresponds to three thin film transistors (three The thin film transistors are adjacent to each other), and the pixel point also has three pixel units, and the three pixel units correspond to the display position, so the thin film transistor corresponding to the pixel unit can be determined according to the thin film transistor corresponding to the display position.

Step S70, sending each of the pulse signals to a driving circuit to display the image, wherein the driving circuit loads a corresponding pulse current value to the thin film transistor corresponding to the pulse signal according to the pulse signal;

The driving circuit is provided with a signal electrode and a wire electrode, and the wire electrode is a closed loop. When the display panel component is working, a current flows through the wire electrode. When the drive circuit receives the pulse signal, the display panel assembly will turn on the thin film transistor switch corresponding to the pulse signal, so that the thin film transistor corresponding to the thin film transistor switch forms a small closed loop, so that the current of the wiring electrode It can flow into the thin film transistor through the thin film transistor switch, and the thin film transistor switch will control the opening of its switch according to the pulse signal to control the current flowing into the thin film transistor, so that the voltage value of the induced electric field where the liquid crystal molecules in the liquid crystal layer is the set voltage The voltage value can determine the twist angle of the liquid crystal molecules in the liquid crystal layer, and the twist angle of the liquid crystal molecules can determine the intensity of the light, that is, the twist angle of the liquid crystal molecules can determine the gray value of the light.

Specifically, after the mobile terminal obtains the grayscale value of the pixel unit in the pixel point, the mobile terminal will generate a corresponding pulse signal according to the grayscale value of the pixel unit, and each pulse signal can correspond to the opening degree of the thin film transistor switch. Adjustment, so that the current in the thin film transistor is the set current value, so that the liquid crystal molecules are in the induced electric field of the set voltage, and then make the liquid crystal molecules twist the corresponding angle to determine the transmittance of the primary color light, and finally make the liquid crystal molecules penetrate the liquid crystal The primary color light of the molecular layer is a preset gray value, so that the image is displayed on the display panel of the mobile terminal.

In the technical solution provided by this embodiment, after the image is generated, the pixels of the image are determined, and the pixel units of the pixels are determined, and a pulse signal is generated according to the pixel unit, and then the thin film transistor corresponding to the pulse signal is determined, and each pulse signal is Send it to the driving circuit, so that the driving circuit loads the corresponding pulse current value and the thin film transistor corresponding to the pulse signal according to the pulse signal, so as to display the image; because the photosensitive area of the mobile terminal is set on the TFT substrate, the area of the photosensitive area is not limited by the size of the camera , so that the quality of the image displayed by the mobile terminal is guaranteed.
