Abstract

The invention provides an embedded display device and a scanning method thereof. The embedded display device includes an embedded display panel, a display controller, a touch driving and detecting controller and a virtual random number generator. The display controller is used for driving the embedded display panel to perform display operation of at least one display frame. The touch driving and detecting controller is connected to a touch layer of the embedded display panel for touch detection. The virtual random number generator is used for generating a random number signal. The display controller divides the display time of at least one display frame into a plurality of display time slots and a plurality of non-display time slots. The display controller further sets the starting time ofthe plurality of non-display time slots according to the random number signal.

Description

technical field [0001] The invention relates to the technical field of built-in display devices, in particular to a built-in display device and a scanning method thereof. Background technique [0002] Competition in the handheld device market is becoming increasingly fierce. Therefore, many functions have been added into the design of the handheld device, such as functions such as touch detection. The conventional technology is to attach the touch layer to the display panel of the handheld device. figure 1 It is a schematic diagram of conventional touch detection and display operations. As shown in the figure, when the display operation is to be performed, gate lines of the display panel are sequentially turned on between vertical synchronous signals (Vsync) to write display signals into pixels corresponding to the gate lines. Since the touch layer is pasted on the display panel, there is a certain distance between the touch layer and the circuit of the display panel, so ...
