Control method of 3D (Three-Dimensional) glasses system

Abstract

The invention discloses a control method of a 3D (Three-Dimensional) glasses system. The control method of the 3D glasses system comprises a pair of 3D glasses. The pair of 3D glasses comprises a glasses frame, liquid crystal glasses lenses and a start control device. 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. Each liquid crystal glasses lens comprises a connecting terminal connected to an LCD (Liquid Crystal Display) drive module in the video control module. The connecting terminal passes through a left glasses frame and a right glasses frame close to a middle node pad and extends into a receiving cavity. The left glasses frame or the right glasses frame comprises a first knob connected to an LCD time sequence adjusting module in the video control module. The first knob is used for the user to manually adjust the amplitude of a time sequence waveform received by the LCD time sequence adjusting module. The light transmittance of the liquid crystal glasses lenses can be manually adjusted directly by this way.

Description

technical field [0001] The invention relates to a control method of a 3D glasses system, in particular to a control method of a 3D glasses system including shutter-type 3D glasses with a simple structure and capable of manually adjusting light transmittance. [0002] Background technique [0003] The shutter-type 3D glasses in the common 3D glasses system generally include a picture frame and mirror legs, wherein the picture frame includes two liquid crystal lenses and a signal receiver, and the signal receiver is used to receive wireless signals (such as infrared video signals, wireless audio signal), and decode the wireless signal, from which the video and audio synchronization signals are decoded, the circuit board and the battery are packaged in the temple, and the circuit board includes a central processing and control unit (such as a central processing chip CPU or a microcontroller MCU, etc.), video signal driving circuit and audio signal driving circuit and other cir...

[0004] However, the shutter-type 3D glasses in this traditional 3D glasses system also have the following disadvantages: the 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 generating Three-dimensional effect, but 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, the light will be too strong and the user will often feel glare. Longer, the visual fatigue is more likely to be harmful to health. Therefore, if the brightness of the shutter 3D glasses (that is, the light transmittance of the liquid crystal lens) can be manually adjusted, it will greatly facilitate the user's needs in use.

[0008] 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
