Problems solved by technology

However, limited by the size of smartphones, image sensors and their modules on current smartphones can only use very small-sized image sensors (such as 1 / 8-1 / 4 inches), equipped with lenses of corresponding size
However, at a certain resolution, a small-sized image sensor means small-sized pixels (for example, 0.9-1.2um), which means that the image quality of an image sensor for a mobile phone cannot be very good. etc.) etc., the image quality is incomparable (the pixel size of a professional camera is usually 4~6um)

Embodiment Construction

[0036] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be further described below in conjunction with the accompanying drawings. Of course, the present invention is not limited to this specific embodiment, and general replacements known to those skilled in the art are also covered within the protection scope of the present invention.

[0037] The image sensor in the traditional smart phone cannot be made too large due to the limitation of the volume of the mobile phone, which limits the improvement of the resolution of the image sensor; the present invention integrates the image sensor pixels and the screen display pixels into the screen, so that Using a large-size screen to overcome the limited size of the image sensor can not only improve the resolution by using a large-size image sensor in a mobile phone, but also reduce the size of the smartphone and realize the miniaturization and high-end of...

Abstract

The invention provides a smart mobile phone screen and system and a preparation method thereof. Screen display pixels and image sensor pixels are integrated in the same screen, and various lens are adsorbed on the mobile phone screen by adsorption rings so that the smart mobile phone screen can be used as an image sensor and can also be used as a regular mobile phone screen. Besides, the pixel region of the image sensor is expanded so that use of large-size image sensor pixels in a mobile phone is enabled to be possible, the imaging quality advantage of the large-size image sensor can be exerted and the size of the smart mobile phone can also be saved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a smart phone screen integrated with a large-size image sensor, a system and a preparation method. Background technique [0002] With the gradual popularity of mobile phone color screens, the material of mobile phone screens is becoming more and more important. The color screen of the mobile phone varies due to the quality of the LCD and the research and development technology. There are roughly two types of LCD and LED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture will be richer. In addition to the above, you can also see some other LCDs on some mobile phones, such as Japan's SHARP GF screen and CG (continuous crystalline silicon) LCD. Compared with the two LCDs, they belong to completely different types. GF ​​is an improvement of STN, which can increase the brightness of LCD, while CG...
