Problems solved by technology

In this way, not only light leakage may occur, but also foreign matter may be generated due to the large opening.
In addition, because the light wire is directly inserted into the CNT set on the PCB, the light bar may be damaged during rework, or the position of the light bar in the backlight module changes due to direct force, affecting the picture

Abstract

The invention provides a printed circuit board, a luminous element, a backlight module and a display device. Connecting points used for being fixedly connected with a connecting line are arranged on prearranged positions on the printed circuit board, and the connecting line is used for enabling the printed circuit board provided with no connectors to be electrically connected with a connector arranged outside the printed circuit board. Therefore, space of the printed circuit board is saved, the size of the printed circuit board is reduced, the yield of the luminous element is increased, and occasions of light leakage occurring on the backlight module are avoided.

Description

technical field [0001] The present invention relates to the field of display technology, and specifically relates to a printed circuit board, a light emitting element, a backlight module and a display device. Background technique [0002] The light source strips in the existing medium-sized and large-sized side-entry backlight modules are soldered with LED4 on the PCB (Printed Circuit Board, printed circuit board). figure 1 shown. At the same time, CNT3 (connector, connector) is required at one or both ends of the PCB. [0003] Generally speaking, the size of CNTs is larger than that of LEDs. Therefore, PCBs will be specially treated at the positions where CNTs are installed, resulting in irregular shapes of PCBs. This will not only increase the size of the PCB, increase the cost of PCB manufacturing, but also reduce Yield rate of light bar processing. [0004] In the design of the backlight module, the backplane corresponding to the CNT part needs to open a via hole for ...
