The invention relates to the dimming technical field of a photoelectrical sensor and a display screen, in particular to a positive-negative (PN) group based generalized photoelectrical intelligent sensor and a display screen dimming system and technology. A plurality of PN nodes are connected with each other through a serial-connection structure to form a PN group with a positive electrode and a negative electrode, when the PN group is illuminated, current is generated in a PN group circuit so as to form an independent signal original signal source, and higher reliability and stability can be realized; and since a good photoelectrical conversion linear relationship can be realized, the photoelectrical sensors can have better consistence in the photoelectric conversion performance. By adopting an embedded information processing module, the comparison of the signal and data can be automatically carried out, and according to an igniting drive control order of a preset intelligent assembled display screen backlight lamp set, the dimming effect can be improved, and the dimming circuit design can be simplified; and a weak single direct current which is identical to a control circuit of the display screen is adopted as the working power of the generalized photoelectrical intelligent sensor and the display screen dimming system, so the design of the circuit can be simplified, and the material and the manufacturing cost can be saved.
Description
technical field [0001] The invention relates to the technical field of photoelectric sensors and display screen dimming, in particular to a wide-area photoelectric intelligent sensor and display screen dimming system and technology based on PN junction groups. technical background [0002] In today's modern society, whether people live entertainment, or study and work, more and more electronic display screens have entered people's life and work. From computers, TVs, mobile phones, and e-books, while modern tools bring people infinite fun and convenience, they also bring more and more harm and threats to people's vision health. Reducing the visual impairment caused by modern electronic display tools is a major issue related to human health and happiness. [0003] Modern electronic display tools are mostly electronic display screens, that is, light patterns of different intensities and colors emitted for people to read and watch. Display the same light pattern and the same l...
