Three dimensional glasses and driving method of the same

Abstract

Three-dimensional glasses include a first driving portion that receives a sync signal from an image display apparatus on which a three-dimensional image is displayed, and generates and outputs a timing signal using the received sync signal; a second driving portion that receives an input voltage and outputs the input voltage using the timing signal; a storage portion that stores information for pairing with the image display apparatus and outputs the stored information on request of the first driving portion; and a lens portion having left and right eye glasses that alternately perform on and off operation based on the output voltage of the second driving portion, wherein the second driving portion and the storage portion are configured of a single chip.

Description

technical field [0001] The present invention relates to three-dimensional (3D) glasses and a driving method for 3D glasses, and in particular to reducing the number of ICs when a driving unit for driving 3D glasses is formed on a printed circuit board (PCB) in the form of an integrated circuit (IC). , in order to achieve miniaturization and simplify the IC structure, thereby reducing power consumption or heat generation of 3D glasses and the driving method of 3D glasses. Background technique [0002] Recently, image display devices provide not only two-dimensional (2D) images but also 3D images with a stereoscopic effect. In particular, image display devices for viewing and listening to stereoscopic 3D images include a glasses system using special glasses and a non-glasses system not using special glasses. The glasses method using special glasses includes the color filter method of separating and selecting images using color filters in a complementary color relationship, an...

Problems solved by technology

[0007] However, in conventional 3D glasses like this, peripheral circuits such as the analog switch 110 are collectively controlled by the RF chip 100, thereby increasing the number of pins (pins) for outputting signals, resulting in high cost, and RF The power consumption of the chip 100, especially the power consumption when receiving an RF signal from an image display device, increases significantly

[0008] Moreover, ICs such as the analog switch 110, the DC / DC converter 130, and the charger 120 other than the RF chip 100 are formed separately on the PCB, thereby increasing the size of the PCB and reducing the space efficiency for configuring the circuit. reduced problem
