Abstract

The invention provides a driving method of a display screen, the display screen and a mobile terminal. The driving method comprises the following steps: detecting the current working mode of the display screen, wherein the working mode comprises a display mode or a touch control mode; setting a conductive metal oxide film to be in the grounding state if the working mode is detected to be the display mode; setting the conductive metal oxide film to be in the high-impedance state if the working mode is detected to be the touch control mode. Therefore, display performance of the display screen in the display state is improved and an antistatic capability is enhanced. As a result, product quality is raised. Furthermore, touch control accuracy of the display screen is improved.

Description

technical field [0001] The present invention relates to the technical field of display screens, in particular to a display screen driving method, a display screen and a mobile terminal. Background technique [0002] With the rapid development of mobile terminal industries such as mobile phones, the use of display screens is becoming more and more extensive. At the same time, the technical requirements for display screens are getting higher and higher. , the existing display screens usually integrate touch technology, the existing touch technology includes plug-in touch technology and embedded touch technology, and the embedded touch technology includes in cell touch technology and on cell touch technology. [0003] With the development of display technology, in cell touch technology has gradually become the mainstream technology for small and medium-sized displays of mobile terminals such as mobile phones. By integrating the touch electrodes into the array substrate, the ima...
