Control method of shutter type 3D eyeglass

Abstract

The invention discloses a control method of a shutter type 3D eyeglass. The shutter type 3D eyeglass comprises an eyeglass frame, a liquid crystal eyeglass lens and a start control device, wherein the start control device comprises a signal receiving module, a power supply management module and a central control module, the central control module comprises a video control module, and the video control module comprises a video processing module, a video regulating module and a video driving module; the liquid crystal eyeglass lens comprises a wire connecting terminal, the wire connecting terminal is connected to the video driving module, and the wire connecting terminal penetrates through a left eyeglass frame and a right eyeglass frame which are close to middle nasal supports of the eyeglass frame to extend into a containing cavity; the left eyeglass frame or the right eyeglass frame comprises a first rotary knob, the first rotary knob is connected to the video regulating module, the first rotary knob is used for manually regulating the size of the amplitude value of a second video synchronizing signal received by the video regulating module by a user, and the light transmission rate of the liquid crystal eyeglass lens can be directly manually regulated in the way.

Description

technical field [0001] The invention relates to a control method of shutter type 3D glasses, in particular to a control method of shutter type 3D glasses with simple structure and capable of manually adjusting light transmittance. Background technique [0002] Common shutter-type 3D glasses generally include a frame and temples, wherein the frame includes two liquid crystal lenses and a signal receiver, which is used to receive wireless signals (such as infrared video signals, wireless audio signals) emitted by 3D TVs, And decode the wireless signal, from which the video and audio synchronization signals are decoded. The circuit board and battery are packaged in the mirror leg. The circuit board includes a central processing and control unit (such as a central processing chip CPU or a microcontroller MCU, etc.), video Circuit structures such as signal drive circuit and audio signal drive circuit, which can synchronize the video synchronization signal and audio synchronizatio...

[0003] However, this traditional shutter-type 3D glasses also has the following disadvantages: this traditional shutter-type 3D glasses can only quickly switch the video perceived by the left and right eyes, that is, realize the function of opening and closing, thereby producing a three-dimensional effect, but not It does not take into account the visual impact caused by the distance between the user and the 3D TV, that is, if the user is relatively close to the 3D TV, he will often feel glare due to the strong light. The longer the viewing time, the easier the vision Fatigue is bad for health. Therefore, if you can manually adjust the brightness of the shutter 3D glasses (that is, the light transmittance of the liquid crystal lens), it will greatly facilitate the user's needs in use.

[0007] In addition, the current shutter-type 3D glasses, because its start-up control module is generally divided into two parts (such as a battery and a circuit board), which are respectively arranged in two temples. The shutter-type 3D glasses with this structure have both temples. It is designed as a two-layer sandwich structure, and its internal space is used for wiring. Therefore, this kind of glasses are generally large in size and heavy in weight. When worn for a long time, the pressure is strong, the structure is also relatively complicated, and the power loss in the transmission process Also larger and more expensive
