Abstract

The invention relates to display equipment, including a touch control module and a touch control adjusting module. When the display equipment is switched to a picture-in-picture (PIP) mode, a menu is displayed to require a user to set a touch control function to support a first or second picture, and after setting is completed, information is transmitted to the touch control adjusting module, and the information includes the display mode of PIP, setting that the touch control function supports the first or second picture, positions and sizes of the first and second pictures, and width and height of a display screen picture; and when the touch control adjusting module receives a touch position output by the touch control module, when the display mode is PIP, the first and second pictures are a primary picture and a sub-picture overlapped on the primary picture, if the touch control function supports the primary picture and the touch position does not fall in the sub-picture, the touch control adjusting module outputs the touch position, and if the touch control function supports the sub-picture and the touch position falls in the sub-picture, the touch control adjusting module corrects the touch position to output the corrected touch position; and thus the touch position can be output correctly.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device with a picture-in-picture (Picture-in-Picture, PIP) and / or double picture (Picture-by-Picture, PBP) display mode and a touch function. Background technique [0002] figure 1 It is a system block diagram of an existing display device with PIP and / or PBP display mode and touch function. See figure 1 , the display device 1 includes a video interface 11 , a scaler 12 , a display screen 13 , a microcontroller 14 and a touch module 15 . The video interface 11 includes a video graphics array (videographics array, VGA) interface and a high-definition multimedia interface (high-definition multimedia interface, HDMI). The display device 1 can be electrically connected to an external computer device (the first video source) through the VGA interface to receive the video S1 output by the computer device, and can be electrically connected to the external video playback device th...
