Abstract

The invention provides a laser pen track recording driving circuit and method, a display device, a driving method of the display device, and a laser pen track recording control system and method, and relates to the technical field of display, and recording of the drawing track of a laser pen on a display screen can be realized. The laser pen track recording driving circuit comprises a resetting module, a photosensitive module, a color-changing pixel driving module, a color-changing pixel capacitor, a display pixel driving module and a display pixel capacitor, wherein the resetting module is used for resetting the photosensitive module under the driving of reset signals and a VDD1, the photosensitive module generates sensitive current when illuminated by laser, the color-changing pixel driving module generates a color-changing voltage signal under the driving of the sensitive current, read signals, the VDD1 and a VDD2, the color-changing pixel capacitor enables color-changing pixels to be colored from transparent under the driving of the color-changing voltage signal, the display pixel driving module generates a constant-white display driving signal when the color-changing pixel driving module generates the color-changing voltage signal, and the display pixel capacitor enables the display pixels to be displayed white under the driving the constant-white display driving signal.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a laser pointer track recording driving circuit and method, a display device and its driving method, and a laser pointer track recording control system and method. Background technique [0002] In daily speeches, if you need to emphasize some important content, you can use the laser pointer to point out a certain point or draw a certain area on the screen to remind the audience to watch the corresponding area. But unfortunately, the area marked by the laser pointer cannot leave traces. In this way, before the audience can clearly see the key information marked by the laser pointer, the track of the laser pointer has disappeared, causing inconvenience for viewing. Contents of the invention [0003] In order to overcome the defects in the above-mentioned prior art, the technical problem to be solved by the present invention is: provide a laser pointer track recording dri...
