Photosensitive assembly

Abstract

The invention relates to a photosensitive assembly comprising a gate electrode, a gate electrode insulating layer, a semiconductor layer, a source electrode, a drain electrode and a channel part between the source electrode and the drain electrode, wherein the source electrode and the drain electrode are arranged on the semiconductor layer; at least one first long comb electrode, at least one first short comb electrode, at least one second long comb electrode and at least one second short comb electrode are respectively arranged on the source electrode and the drain electrode; and the first long comb electrodes, the first short comb electrodes, the second long comb electrode and the second short comb electrodes are ranked in a long and short staggered manner. According to the invention, the area of a photosensitive region can be enlarged in a limited space of the photosensitive assembly to ensure that the photosensitive efficiency is greatly enhanced, thus the difficulty in the current industry can be solved.

Description

Technical field The invention provides a photosensitive component, in particular a photosensitive component arranged in a liquid crystal display for sensing ambient light sources. Background technique Liquid crystal displays are widely used in portable information devices such as notebooks and personal digital assistants (PDAs) due to their light and thin appearance, low power consumption, and no radiation pollution. . Recently, as the functions of portable information devices are becoming more and more complex, and the requirements for their display quality are increasing, how to clearly present images both indoors and outdoors has become an important subject of current liquid crystal display technology. Under such demand, technologies such as transflective mode liquid crystal display technology and ambient light sensor (ALS) have emerged. Through ALS technology, the system can measure the intensity of ambient lighting and adjust the backlight brightness of the liquid cr...

Problems solved by technology

However, even though the current ALS technology can directly integrate the function on the substrate of the liquid crystal display, saving the need for an additional independent brightness sensor, how can it sense the most appropriate ambient light source in a limited space to reduce cost pressure and space constraints? Limitations still need to be worked on
