Abstract

The invention relates to an organic light-emitting diode display of an integrated touch screen, which comprises a base plate and a light-emitting diode display array arranged at one side of the base plate. The light-emitting diode display array comprises a thin film transistor layer which comprises a grid conducting layer, a source / drain conducting layer and a pixel electrode layer arranged in sequence. The light-emitting diode display also comprises a touch control array, the touch control array is arranged on the base plate at the same side of the light-emitting diode display array and comprises a detecting layer, and the detecting layer is formed by one of the grid conducting layer, the source / drain conducting layer and the pixel electrode layer of the thin film transistor layer. The integrated touch screen improves the display effect of the organic light-emitting diode display without increasing the manufacturing cost.

Description

technical field [0001] The invention relates to an organic light emitting diode display integrated with a touch screen. Background technique [0002] Flat panel display technology has been widely used because of its small size and portability. Organic Light Emitting Diode (OLED) display technology is the most possible technology for future flat-panel displays. Compared with Liquid Crystal Display (LCD) technology, OLED displays use the self-illuminating mode of each pixel to replace the unified backlight mode, so the viewing angle of the organic light-emitting diode display is significantly increased, the power consumption is reduced, the contrast ratio is improved, and the screen thickness is thinned. [0003] As a modern input method, the touch screen function has become one of the main forms of input methods. In portable electronic products such as mobile phones, cameras, and e-books, it has gradually replaced the traditional mechanical button input method, and finally r...
