Display device, display system and control method

Abstract

The invention discloses a display device, a display system and a control method, which are used to realize synchronous interaction between a terminal and a liquid crystal display device, and at the same time ensure the consistency of contacts between the display and the terminal. The display device includes: a receiving module for receiving an image frame, a first decoder for decoding the image frame, a display module for outputting and displaying the decoded image data, and a display module for responding to user The touch control module of the image display command corresponding to the touch point on the touch screen is used to read the first coordinate data of the user's touch point on the touch screen. The corresponding relationship of the resolution of the terminal, the single-chip microcomputer for converting the first coordinate data into the second coordinate data, the encoder for generating the control frame containing the second coordinate data, and the encoder for sending the control frame to The sending module of the terminal.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display device, a display system and a control method. Background technique [0002] In the prior art, the structure of the wireless display device is as follows figure 1 As shown, the device includes a display module 11 , a key input part 12 , a control module 13 , and a wireless module 14 , wherein the wireless module includes a receiving end 141 , a sending end 142 , a decoder 143 and an encoder 144 . figure 1 The wireless display device shown in , receives the image frame from the terminal through the receiving terminal 141, and the decoder 143 decodes the image frame to obtain the decoded image data, which is sent to the display module 11 through the control module 13, and the display module 11 The decoded image data is processed for output and display; the key input part 12 receives the image control command sent by the user, and the command is forwarded t...

[0003] However, in this interactive mode, since the amount of data contained in the image frame and the control frame is relatively large, in order to ensure the image transmission speed and effective rate, the transmission speed should be greater than 500Mbps, otherwise a large amount of data transmission will cause the link to be blocked and delay, affecting the synchronous interaction between the terminal and the liquid crystal display device, making it difficult to achieve real synchronous display
