Positioning system and control system of remote control coordinate and display apparatus thereof

Abstract

The invention relates to a remote-control coordinate positioning system, a control system and a display device thereof. The remote-control coordinate positioning system comprises a liquid crystal panel, a backlight plate, a plurality of infrared sources and a directional remote controller, wherein the liquid crystal panel includes a plurality of display blocks; the plurality of infrared sources are configured behind the liquid crystal panel and are respectively arranged according to the display blocks for transmitting infrared light capable of penetrating the liquid crystal panel; and the directional remote controller is used for receiving the infrared light emitted by the infrared sources and further pointing to the position information of the liquid crystal panel. The infrared sources can be superposed with liquid crystal display pixels so as to accurately construct the quasi-coordinate relationship between the infrared sources and the pixels. The outside directional remote controller can accurately acquire the pointed coordinate information without considering the distance and the size of the display screen; and the display device can control outside controlled devices according to the video condition played by the display device or other control parameters to interact with the display device.

Description

technical field [0001] The present invention relates to a technology related to a control system, and in particular to a control system, a remote control coordinate positioning system and a display device with the system. Background technique [0002] In recent years, due to the rapid development of technology, audio-visual game equipment has also become more and more popular. And the most popular audio-visual game equipment recently is the Wii game console of Nintendo. The success of the Wii game console lies in the innovation of the product, the change of the gameplay, the sensor joystick can be controlled by one hand, and the easy-to-use game software, so that the player can use real strikes, swings and actions on the display screen. Images for interaction. Therefore, more game fun can be generated. Nintendo has also applied for many related controller patents, such as US Patent Application Early Publication Nos. US20070049374 and US20070052177 and so on. [0003] Fig...

AI Technical Summary

Problems solved by technology

If the remote controller (70, 76) held by the user is closer to the display, the above-mentioned coordinate position correspondence will be destroyed, that is to say, if the user is not standing at the position where the coordinate position correspondence relationship was originally established, such as from If the display is slightly closer or farther away, since these reference light sources 8L and 8R do not have a spatial correspondence with the pixels displayed on the display, the coordinates positioned by the remote controller (70, 76) will be inaccurate, causing the user Operational inconvenience

In addition, when the size of the display becomes larger, the user has to stand farther away from the display to establish the correspondence between the coordinates and positions. Invisibly, the user is limited in space when using this coordinate positioning system.
