Display device and method for splitting display pictures and transmitting pictures to different display units to be displayed

Abstract

The invention discloses a display device and method for splitting display pictures and transmitting pictures to different display units to be displayed. According to the device and the method, a main display unit and subordinate display units are selected from a plurality of display units; a display picture is split into sub display pictures corresponding to all the display units according to all display unit picture display sizes when the main display unit generates a display picture, and all the display units display the corresponding sub display pictures synchronously after the generated sub display pictures are sent to the corresponding subordinate display units, accordingly, the display units can be combined to display the same picture, the display range is increased, and the display picture is amplified.

Description

technical field [0001] The present invention relates to a display device and a display method, in particular to a display device and a method for dividing a display screen and transmitting it to different display devices for display. Background technique [0002] With the advancement of technology, in addition to receiving information from traditional newspapers, magazines and television, people carry mobile phones and liquid crystal displays (LCDs) that can be seen everywhere also provide a wealth of information. [0003] Since portable display devices such as mobile phones are usually not large, the area where information can be displayed is not too large. However, in some cases, a larger display area may be required. For example, when you want to share the information displayed on the mobile phone with multiple people, the information displayed on the mobile phone can only be viewed by two or three people at the same time. If you want to share If there are too many peopl...

Problems solved by technology

[0005] However, erecting a video wall requires complex and expensive control equipment, which is usually beyond the reach of ordinary users

Furthermore, the signal source of the TV wall comes from the external devices of the monitors that make up the TV wall, which makes the whole structure complex, and the monitors on the TV wall cannot be moved and combined at will, lacking flexibility. If portable devices such as mobile phones are used as monitors for display, then There is a lack of uniformity among various portable devices, and it is impossible to truly display the technical effect of the same picture in high definition

[0006] In summary, it can be seen that there has been a problem in the prior art that portable display devices cannot be combined to display the same picture for a long time, so it is necessary to propose improved technical means to solve this problem
