Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] figure 1 It is the working principle diagram of the shutter type 3D glasses in the prior art, such as figure 1 As shown, the 3D_Vsync synchronization signal of the TV represents the reference information of the left and right eye switches. The TV sends the synchronization signal to the 3D glasses in the form of infrared or radio frequency. The 3D glasses start to receive the signal, first in the working mode, capture the synchronization signal,...

Abstract

The invention relates to the technical field of 3D glasses and provides an energy-saving control method of the 3D glasses. The method can be applied to the 3D glasses with a receiving unit, which comprises the following steps of: A, receiving a synchronous signal; B, judging whether the synchronous signal is valid or not, if so, leading the 3D glasses to enter a synchronous mode, leading the receiving unit to enter a dormant state, and executing the step C, and otherwise, going back to the step A; and C, capturing synchronous signals once at intervals of N synchronous cycles. By applying the invention, the capture time of the synchronous signal can be greatly shortened, the power consumption can be reduced and the product can be ensured to work stably. The method provided by the inventionis suitable for various types of active shutter type 3D glasses.

Description

technical field [0001] The invention relates to the technical field of 3D glasses, in particular to an energy-saving control method for 3D glasses. Background technique [0002] Along with popularization of 3D TV, the shutter type 3D glasses that appear on the market are also increasing day by day. The early 3D glasses mainly used the infrared method, that is, the 3D synchronous signal (left and right eye switching signal) was sent from the TV end to the glasses end through infrared, and the glasses recognized the signal after receiving the signal, and at the same time controlled the conduction of the left and right lenses. The biggest disadvantage of infrared glasses is that they are susceptible to interference from external objects, so 3D glasses are gradually adopting other working methods such as Bluetooth and radio frequency. For example, Samsung uses Bluetooth 3D glasses; LG uses RF2.4G radio frequency 3D glasses. A big problem brought about by this is the multiplicat...
