A light hole 8 is formed in one side of the substrate 1 corresponding to the position of any one of the plurality of photoelectric devices 5, a light guide plate 6 is arranged on any one of the plurality of photoelectric devices, and the light guide plate 6 surrounds the corresponding photoelectric device 5 and the light hole 8;
The photoelectric devices 5 and the main key 7 are respectively connected with the main control unit in a signal mode.
In the embodiment of the present invention, only some components of the television are described, and the components not described may be implemented with reference to the prior art, and the embodiment of the present invention is not described one by one.
The operation principle of the single-key optical control borderless television is as follows: under the normal playing condition, the backlight module and the liquid crystal module are matched to realize the display of pictures; when the outside needs to control the television, the main key triggers the main control unit to drive the liquid crystal module to display the OSD control console, then the photoelectric device 5 captures the luminous flux change condition of the display area of the OSD control console synchronously, and the touch area of the outside to the OSD control console is judged according to the luminous flux change condition, so as to judge the control instruction issued by the user and execute the control instruction.
Specifically, the backlight device performs light dispersion through the diffusion plate, so that the backlight module can emit uniform backlight light, and the backlight light displays specific colors through light treatment of the liquid crystal module and is combined to form a picture. For the photoelectric device, since the diffusion plate has an irregular divergence effect on the light, the light reversely emitted from the diffusion plate can pass through the light holes 8 and be received by the photoelectric device (under the guidance of the light guide plate), and the photoelectric device can convert the acquired light signal to generate a feedback signal; specifically, the sources of the optical signals acquired by the photoelectric device include light rays of the backlight device and external light rays, when objects such as fingers touch the surface of the liquid crystal module, on one hand, the objects such as fingers can block the external light rays, and on the other hand, the objects such as fingers have a certain reflection function and can reflect the light rays transmitted out of the liquid crystal module into the diffusion plate; because the diffusion of the diffusion plate has a certain range, the light intensity of the diffusion plate area can be locally changed under the superposition of the two conditions; correspondingly, the light intensity of the light reversely emitted from the area of the diffusion plate can be correspondingly changed; the amount of light variation is indistinguishable to the naked eye, but can capture this subtle variation in the photovoltaic device.
It should be noted that, the object such as a finger will block the external light and cause the reverse light intensity of the corresponding area of the diffusion plate to be weakened, and the reflected light will cause the directional light intensity of the corresponding area of the diffusion plate to be increased, but in practical implementation, it is found that the situation of offset occurs under the condition that the superposition of the two is very small (the influence of the external light on the reverse light intensity is smaller), so that the situation of offset of the two can not be considered in specific setting.
Optionally, in order to simplify the manufacturing process, the main key is optionally bonded on the circuit board and is processed with other devices through an SMT process, and specifically, the main key may be a physical key or a photoelectric key.
Optionally, any one of the plurality of photoelectric devices is correspondingly provided with a plurality of light holes. The light holes are arranged along the up-down direction of the drawing, the aperture can be correspondingly reduced, and the inner walls of the light holes can be sprayed with light absorbing materials; through this embodiment, the usable light trap filters the light of wide-angle incidence, avoids the luminous direct light trap that passes through of backlight unit, simultaneously, the light that the light trap obtained is only to its just to the diffuser plate region, and the counterpoint effect is better to avoid discernment mistake.

Therefore, the main control unit starts to execute the corresponding flow after receiving the trigger signal of the main key.
Specifically, after receiving the trigger signal of the main key, the main control unit sends a control display signal to the liquid crystal module, wherein the display signal enables the liquid crystal module to display a console in a preset area.
Synchronously, the main control unit starts to receive and process the feedback signal of the photoelectric device.
Specifically, the starting of the photoelectric device can be activated through the main key so as to reduce the overall power consumption of the television. Further, only the optoelectronic device corresponding to the area of the console may be awakened.

Further, if the trigger signal disappears in the preset time, the control display signal stops generating. According to different preset time, the display of the control console can be delayed display or real-time display; when the display is performed in real time, the preset time is short, the user needs to operate by two hands, one hand continuously presses the main key, and the other hand operates to prevent the display of the console from disappearing.
S102, judging whether the position corresponding to the photoelectric device is selected or not according to the change condition of the feedback signal of the photoelectric device in the preset area;
