Problems solved by technology

The layering of the touch screen and the display screen makes the touch panel display thicker and heavier and increases the cost; when the touch screen is placed in front of the display screen, the reflection generated by the sensing electrodes of the touch screen will make the display uneven and strong. The decrease of the display contrast in the external light environment affects the display effect

Abstract

The invention discloses an active touch flat-panel display. A separated active touch system is manufactured on substrate glass of an active panel display. By means of existing technology of the active flat-panel display, the active touch system is manufactured on the substrate glass of the active flat-panel display in existing manufacturing processes of the active flat-panel display, so that the active flat-panel display simultaneously has an active display system and the active touch system, and the active display and an active touch screen are integrated. The active touch flat-panel display is light and thin. Active components are installed on the active touch screen, each sensing electrode unit on the screen can work independently, judgment of multiple point touch is accurate, and multiple point touch is easy and natural.

Description

technical field [0001] The invention relates to a touch screen and a display, in particular to an active touch system and an active flat panel display. Background technique [0002] At present, flat-panel displays with touch functions are composed of display screens, display drivers, touch screens, touch signal detectors, backlights and other components. Touch screens include resistive, capacitive, electromagnetic, Ultrasonic type and photoelectric type, etc., the display screens include TN / STN liquid crystal display, TFT liquid crystal display, OLED display, PDP display, carbon nanotube display, etc. A flat panel display with a touch screen laminates a separate touch screen and a display screen, detects the plane position of a touch point through the display screen, and then makes the cursor on the display screen follow the touch point. The layering of the touch screen and the display screen makes the touch panel display thicker and heavier and increases the cost; when the...
