Abstract

The invention discloses a triode display with an image sensing function, and the display comprises a plurality of pixels; each pixel comprises three sub-pixel units and three image sensing units, a driving backboard carries the plurality of pixels and drives the sub-pixel units to emit light, and the sub-pixel units emit light according to the configured image sensing units. According to the invention, the vertical oxide transistor (VDMOS) device is prepared on the surface of the driving backboard through the semiconductor technology, the VDMOS device has the advantages of high carrier mobility, low response time, simplified external circuit and the like, intrinsic amplification is provided for carriers through the conductance gain of the transistor, and the electric noise in the micro-display device can be obviously reduced; therefore, high-gain driving of the high-resolution micro-display is realized.

Description

technical field [0001] The invention relates to a triode display equipped with an image sensing function, and belongs to the field of display manufacturing. Background technique [0002] With the continuous development of display technology, the application range of display panels is becoming wider and wider, and people's requirements for display panels are also getting higher and higher.
