Description

technical field

[0001] The invention relates to a touch screen and a flat panel display, in particular to a touch type 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 touch screen...
