The invention discloses a photosensitive photoelectric device drive control circuit and a display device, and the circuit comprises a switch switching circuit, wherein the common end of the switch switching circuit is connected with the anode of a photosensitive photoelectric device and the switch switching circuit has a first working state and a second working state; a photosensitive photoelectric device driving circuit, wherein the output end of the photosensitive photoelectric device driving circuit is connected with the first connecting end of the switch switching circuit; a photosensitivedetection circuit, wherein the detection end of the photosensitive detection circuit is connected with the second connection end of the switch switching circuit; in the first working state, the switch switching circuit controls the photosensitive photoelectric device driving circuit to be electrically connected with the photosensitive photoelectric device so as to drive the photosensitive photoelectric device to emit light; and in the second working state, the switch switching circuit controls the photosensitive detection circuit to be electrically connected with the photosensitive photoelectric device so as to receive an optical signal acquired by the photosensitive photoelectric device. The problems that the multifunctional display screen manufactured in an SIP, heterogeneous integration or monolithic integration mode is high in cost and complex in manufacturing process are solved.
Description
technical field [0001] The invention relates to the technical field of photosensitive photoelectric devices, in particular to a photosensitive photoelectric device driving control circuit and a display device. Background technique [0002] With the development of display technology, the requirements for display technology are getting higher and higher. The new type of display not only needs to have the function of display, but also needs to continuously expand other functions, such as the ability to perceive the environment, and the communication ability between display and display. These requirements place new demands on traditional display technologies. At present, various functional modules are usually combined through system-in-package (SIP), heterogeneous integration or monolithic integration to meet the requirements of display technology. Such a manufacturing process is tedious, increases the manufacturing cost, reduces the degree of integration, and may fail to achi...
