Problems solved by technology

[0006] 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

Abstract

The invention relates to a sensitization module, characterized in that: the sensitization module comprises a gate, a gate insulation layer, a semiconductor layer, a source electrode, a drain and a channel part between the source electrode and drain. The source electrode and drain are set on the semiconductor layer and comprise at last one first long comb electrode and at least one first short comb electrode and at least one second long comb electrode and at least one second short comb electrode. The first long comb electrode, the first short comb electrode, the second long comb electrode and the second short comb electrode are arranged in way of long-short stagger. The sensitization module increases sensitization area and greatly increases sensitization efficiency in the limited sensitization module space, in order to solve current dilemma.

Description

【Technical field】 [0001] The invention provides a photosensitive component, especially a photosensitive component arranged in a liquid crystal display for sensing ambient light sources. 【Background technique】 [0002] Liquid crystal displays are widely used in portable information devices such as notebook computers (notebooks) and personal digital assistants (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 become increasingly complex, the display quality requirements are increasing. How to display images clearly both indoors and outdoors has become an important issue in current liquid crystal display technology. Under such demands, technologies such as transflective mode liquid crystal display technology and ambient light sensor (Ambient Light Sensor, ALS) are produced. [0003] Through ALS technology, the system can measure the intensity ...
