Embodiment 1

[0112] The TFT image sensing array film (that is, the photodetection array film) is an array formed by photosensitive diodes, and the array formed by the photosensitive diodes includes a photodiode sensing area. Existing liquid crystal display (LCD) panels or organic light-emitting diode (OLED) display panels all use a TFT structure to drive and scan a single pixel to realize the display function of the pixel array on the panel. The main structure forming the TFT switching function is a semiconductor field effect transistor (FET). The well-known semiconductor layer materials mainly include amorphous silicon, polycrystalline silicon, indium gallium zinc oxide (IGZO), or organic compounds mixed with carbon nanomaterials, etc. . Since the structure of the light-sensing diodes can also be prepared using such semiconductor materials, and the production equipment is also compatible with the production equipment of TFT arrays, TFT light-sensing diodes (ie, photodiodes) have begun to ...

Embodiment 2

[0118] On the basis of using the first embodiment, in order to improve the quantum efficiency of photoelectric conversion, the amorphous silicon photodiode can also be formed by stacking p-type / i-type / n-type structures above double junctions. The p-type / i-type / n-type material of the first junction layer of the photodiode is still an amorphous silicon structure, and the p-type / i-type / n-type material above the second junction layer can be a microcrystalline structure, a polycrystalline structure or doped with Compound materials that can extend the photosensitive wavelength range. In short, multiple sets of p-type / i-type / n-type structures can be stacked up and down to form a photodiode structure, and for each p-type / i-type / n-type structure, the photodiode structure described in Embodiment 1 is used .

Embodiment 3

[0120] On the basis of using Embodiment 1 or Embodiment 2, for each p-type / i-type / n-type structure, the p-type semiconductor layer contained therein may be a multi-layer structure with more than two layers. For example, the p-type semiconductor layer has a three-layer structure, including a first p-type semiconductor layer (p1 layer), a second p-type semiconductor layer (p2 layer), and a third p-type semiconductor layer (p3 layer) from top to bottom. Among them, the p1 layer can adopt an amorphous structure and be heavily doped with boron (the concentration of boron is more than twice that of the standard process); The thinned p2 and p3 layers reduce the absorption of light, so that as much light as possible enters the i layer and is absorbed by the i layer, improving the photoelectric conversion rate; on the other hand, the p2 layer and p3 layer use normal boron doping It can effectively avoid the deterioration of the built-in potential due to the heavy doping of the p1 layer...

Abstract

The invention provides a touch component operation method and device capable of synchronously verifying fingerprint information. The touch component operation method is applied to the touch componentoperation device capable of synchronously verifying fingerprint information. The touch component operation device comprises a display unit and a sensing unit, wherein a fingerprint recognition area isarranged on the display unit, and the sensing unit is located below the fingerprint recognition area and used for obtaining the fingerprint information on the fingerprint recognition area; and the display unit is used for displaying at least one touch assembly in the fingerprint identification area. The touch component operation method comprises the following steps: receiving an operation instruction of a finger of a user on a touch component, and synchronously collecting fingerprint information corresponding to the finger of the user. According to the scheme, the operation steps of user fingerprint collection can be effectively reduced, and the user experience is improved.
