Specifically, the parameter adjusting module 3 shown in fig. 2 includes three current signal input terminals B1, and if the parameter adjusting module 3 detects that the input currents of the three current signal input terminals B1 change at different times according to a certain sequence, and the sequence of the input currents of the current signal input terminals B1 of the parameter adjusting module 3 corresponds to the gesture sequence of the light sensing module 21 shielded by the touch subject, the parameter adjusting module 3 can accordingly determine the gesture sequence of the touch subject shielding the light sensing module 21 and adjust the operating parameters of the terminal device according to the gesture sequence.
Illustratively, as shown in FIG. 2, may be providedThe light sensing module 21 includes a phototransistor T having a source b2 and a drain b3, the source b2 or the drain b3 of the phototransistor T can be configured as the current signal output A1 of the light sensing module 21, the drain b3 of the phototransistor T can be configured as the current signal output A1 of the light sensing module 21, and the source b2 of the phototransistor T can be connected to a fixed potential V1.

For example, as shown in fig. 2, when the parameter adjusting module 3 detects that the input current at the current signal input terminal B1 sequentially changes at different times in the left-to-right sequence, that is, the input current at the current signal input terminal B1 corresponding to the light sensing module 211 changes first, the input current at the current signal input terminal B1 corresponding to the light sensing module 212 changes first at the next time, and the input current at the current signal input terminal B1 corresponding to the light sensing module 213 changes first at the next time, the parameter adjusting module 3 adjusts the brightness adjusting signal output by the brightness adjusting signal output terminal C according to the sequence of the electrical signals output by the light sensing module 21, and the brightness adjusting signal can increase the duty ratio of the PWM signal output by the pulse signal output terminal of the system terminal control module 10, the duty ratio of the PWM signal is the ratio of the effective signal for adjusting the brightness of the backlight module 5 in the PWM signal, the luminance of the backlight module 5 is in direct proportion to the duty ratio of the PWM signal, and the backlight control module 4 adjusts the luminance of the backlight module 5 to increase, whereas for the liquid crystal display device, the luminance of the backlight module 5 increases, and the luminance of the display device 1 increases. Here, the change value of the current is used as a determination criterion, that is, a difference value between the output electrical signal of the photo sensing module 21 when being blocked by the touch subject and the output electrical signal of the photo sensing module 21 when not being blocked by the touch subject is used as a determination criterion, so that the influence of ambient light or backlight of the display device on the determination result can be effectively avoided.
When the parameter adjusting module 3 detects that the input current of the current signal input terminal B1 changes sequentially at different moments in the order from right to left, that is, the input current of the current signal input terminal B1 corresponding to the light sensing module 213 changes first, the input current of the current signal input terminal B1 corresponding to the light sensing module 212 changes first at the next time, the input current of the current signal input terminal B1 corresponding to the light sensing module 211 changes first at the next time, the parameter adjusting module 3 adjusts the brightness adjusting signal output by the brightness adjusting signal output terminal C according to the sequence of the output electrical signals of the light sensing module 21, and the brightness adjusting signal can reduce the duty ratio of the PWM signal output by the pulse signal output terminal of the system terminal control module 10, and the backlight control module 4 adjusts the brightness of the backlight module 5 to reduce, so that the brightness of the display device 1 is reduced.
When the parameter adjusting module 3 detects that only the current signal input terminal B1 is set, for example, only the input current of the current signal input terminal B1 corresponding to the light sensing module 211 changes, the parameter adjusting module 3 adjusts the brightness adjusting signal output by the brightness adjusting signal output terminal C, and the brightness adjusting signal enables the duty ratio of the PWM signal output by the pulse signal output terminal of the system terminal control module 10 to be the minimum value, the light emitting brightness of the backlight module 5 is the minimum, the brightness of the display device 1 is the minimum, for example, the display device 1 is turned off. Accordingly, the terminal device utilizes the virtual gesture key 2 formed by the light sensing modules 21 to adjust the brightness of the display device 1 according to the sequence that the touch subject blocks the light sensing modules 21, that is, the touch gesture of the user.

Illustratively, as shown in fig. 3, when the parameter adjusting module 3 detects that the input current at its current signal input terminal B1 changes sequentially at different times in the order from left to right, the parameter adjusting module 3 outputs a brightness adjusting signal through a brightness adjusting signal output terminal C, and the driving module 8 increases the gray-scale voltage output to the pixel unit according to the brightness adjusting signal. Referring to fig. 1 and 3, the display panel 11 includes a plurality of pixel units (not shown), the driving module 8 may be connected to each pixel unit in the display panel 11 and output a gray-scale voltage to the corresponding pixel unit, the gray-scale voltage is proportional to the brightness of the pixel unit in the display panel 11, the gray-scale voltage increases, the brightness of the display device 1 increases, and the display device 1 may be an organic light emitting display device or a liquid crystal display device. When the parameter adjusting module 3 detects that the input current of the current signal input terminal B1 sequentially changes at different times in the order from right to left, the parameter adjusting module 3 outputs a brightness adjusting signal through the brightness adjusting signal output terminal C, and the driving module 8 decreases the gray-scale voltage output to the pixel unit according to the brightness adjusting signal, so that the brightness of the display device 1 decreases.
