Abstract

The embodiment of the invention discloses a micron light-emitting diode matrix display, which comprises a plurality of pixel circuits, wherein each pixel circuit comprises a micron light-emitting diode, and the micron light-emitting diodes are connected to a driving power supply through a first switch and a second switch; a first scanning line connected to the control end of a third switch; a dataline connected to the control end of a second switch through the third switch; a second scanning line connected to the control end of a fourth switch; a third scanning line connected to the control end of the first switch and used for cutting off the first switch at the optical communication receiving time so as to cut off the power supply of the driving power supply to the micrometer light-emitting diode; and a photosensitive unit connected to the data line through the fourth switch so as to transmit a photosensitive signal to the data line when the fourth switch is switched on. According tothe technical scheme provided by the embodiment of the invention, the micrometer light emitting diode and the photosensitive unit are arranged, so that the technical effects of transmitting and receiving optical signals are achieved.

Description

technical field [0001] Embodiments of the present invention relate to visible light communication technology, and in particular to a micron light-emitting diode matrix display. Background technique [0002] With the rapid development of light-emitting diodes, light-emitting diodes are used in many occasions. Visible light communication technology relies on high-speed flashing signals sent by light-emitting diodes to transmit information. [0003] At this stage, the network access technology is usually wireless radio frequency communication. Because of the increase in the number of electronic devices, especially people's demand for video services "Anywhere, Anytime", wireless spectrum resources are greatly consumed. The 380-780nm spectral bandwidth (equivalent to 405THZ) of visible light can be used to alleviate this problem. At this stage, visible light communication technology uses light-emitting diodes as light sources, which can realize both lighting functions and data ...
