Title:
MICRON LIGHT-EMITTING DIODE MATRIX DISPLAY
Document Type and Number:
WIPO Patent Application WO/2020/252877
Kind Code:
A1
Abstract:
A micron light-emitting diode matrix display (10), comprising: a plurality of pixel circuits (100), each comprising a micron light-emitting diode (101), and the micron light-emitting diodes (101) being connected to a driving power supply (111) by means of a first switch (107) and a second switch (108); a first scanning line (102) connected to a control end of a third switch (109); a data line (103) connected to a control end of a second switch (108) by means of the third switch (109); a second scanning line (104) connected to a control end of a fourth switch (110); a third scanning line (105) connected to a control end of the first switch (107) and configured to cut off the first switch (107) at the optical communication receiving time so as to cut off the power of the driving power supply (111) to the micrometer light-emitting diode (101); and a photosensitive unit (106) connected to the data line (103) by means of the fourth switch (110) and configured to transmit a photosensitive signal to the data line when the fourth switch (110) is switched on.
