AI Technical Summary

Problems solved by technology

like figure 2 As shown, the second video signal (video B) is shrunk to a size smaller than a quarter of the display area 100, so that the audience who wants to watch the second video signal (video B) cannot clearly see the second video signal (Video B)
Moreover, because the pixels originally used to display the first video signal (Video A) are converted to display the second video signal (Video B), the viewer watching the first video signal (Video A) may miss the first video signal (Video A). Some key images (Video A), not to mention subtitles would be missed by the second video signal (Video B)

Embodiment Construction

[0073] Please refer to image 3 , image 3 It is a timing diagram of displaying multiple full-screen video signals on a display screen in an embodiment of the present invention. Such as image 3 As shown, the first video signal (Video A) and the second video signal (Video B) can be displayed on the display screen. From time t0 to time t1, the first video signal (video A) can be displayed on the display screen. Then, from time t1 to time t2, the second video signal (video B) can be displayed on the display screen. Additionally, from time t2 to time t3, the display screen displays a first video signal (Video A), and from time t3 to time t4, the display screen displays a second video signal (Video B).

[0074] The shutter glasses have left and right eye liquid crystal filters that control how light passes through or blocks it. Traditionally, shutter glasses are used to watch stereoscopic images. The principle is that at the same time, only one of the left-eye and right-eye l...

Abstract

The invention discloses a display system and a method for displaying multiple full-screen video signals on display screen. The display system includes a first video source for outputting a first video signal, a second video source for outputting a second video signal, a display module for displaying an image frame, a system control module for receiving the first video signal and the second video signal, and generating an image signal comprising alternating full-screen image frames of the first and second video signals. Therefore, the invention enables each viewer to watch the program which is selected by him or her in the full screen without being interfered by other programs which are displayed on the same display screen.

Description

technical field [0001] The present invention relates to a display system and its method, especially to a display system and its method for displaying multiple full-screen video signals. Background technique [0002] Televisions allow viewers to watch live or pre-recorded video from a TV channel or from an external source such as a DVD player, Blu-ray player or camcorder. Due to the advancement of display technology (such as liquid crystal display, plasma display and organic light-emitting diode display), TV sets are now developing towards the trend of increasing size, reducing thickness and lighter weight, and also due to the advancement of the above-mentioned display technology. The resolution of the display. [0003] Most television sets are placed in the family for family members to watch TV programs together. However, since different family members have different program preferences, disputes often arise over which programs to watch. In order to solve the above proble...
