Problems solved by technology

[0006] However, in order to achieve the above effects, it is necessary to replace light sources with different wavelengths when the thickness of the active layer is different, such as using a laser pointer with a different wavelength, which increases the cost and makes the versatility of the photosensitive TFT low, which limits the photosensitive TFT. The use and development of TFT

Description

technical field [0001] The invention relates to the field of display technology, in particular to a photosensitive device and a display panel. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is widely used in the current flat panel display industry because of its light, thin, small and other characteristics, low power consumption, no radiation, and relatively low manufacturing cost. In order to broaden the commercial and household functions of liquid crystal displays, many functions are now integrated into the display, such as color temperature sensing, laser sensing, or gas sensing, to improve the applicable scenarios of liquid crystal displays. However, many integrated functions are in the new development stage, and there are still many processes and related designs that need to be improved in order to improve the performance of various integrated function LCDs. [0003] At present, in order to enable the display to have the functions o...
