LIGHT-EMITTING DIODE DISPLAY SCREEN

摘要

A Light Emitting Diode (LED) display screen includes: an LED display screen substrate (200), wherein the LED display screen substrate (200) is arranged with a driving circuit, an output end of the driving circuit includes: a first positive electrode (202) and a first negative electrode (204); an LED chip (210), located on the first surface,; a first jointing part (222) and a second jointing part (204), wherein the first positive electrode (202) is jointed to and electrically connected to the second positive electrode (212), and the first negative electrode (204) is jointed to and electrically connected to the second negative electrode (214) by the second jointing part (224). The LED display screen solves the technical problem in the related art that the minimum dot pitch of an LED display screen is excessively large due to a limited size of a support in a conventional encapsulated lamp bead.
