Problems solved by technology

This greatly reduces the antistatic ability of the backlight, increases the probability of the display panel being damaged by static electricity, and increases the complexity of the panel design of the display panel.
[0004] When there is a metal backplane, it can play an electrostatic shielding effect on the display panel panel and the light bar inside the backlight; when there is no metal backplane, the backlight cannot play an electrostatic shielding effect. The antistatic ability is greatly reduced, which may cause damage to the panel or cause the light bar to burn out from time to time

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0031] figure 1 It is a structural schematic diagram of a backlight with a metal backplane in the prior art. It can be seen from the figure that the backlight in the prior art is provided with a metal backplane 1 outside, and the metal backplane 1 is fixed on the backlight through a plastic frame 2 , while the metal backplane 1 is also in contact with the reflection sheet 14 . Therefore, during ESD, the static electricity on the reflection sheet 14 and the static electricity of the light bar 3 can be derived through the metal back plate 1, so that the static electricity of the backlight can be released, which can play a role in the display panel 8 and the light bar 3 inside the backlight. Static shielding e...

Abstract

The invention provides a backlight source, a display panel and a display device. A ground lead is arranged on a flexible printed circuit board (FPC) of the backlight source, a reflective sheet is arranged to be a conductive reflective sheet, static electricity of the conductive reflective sheet is conducted to the ground lead through conductive adhesives, the static electricity is conducted out through the ground lead, therefore, the anti-static electricity capacity of the backlight source is improved, failure is prevented from being caused due to the fact that the backlight source is damaged by the static electricity, and the static electricity is prevented from damaging the display panel. In addition, a metal backboard is omitted, therefore, the thickness of the backlight source is reduced, and lightening and thinning of the backlight source can be guaranteed. The display panel and the display device manufactured by the backlight source also can have the good anti-static electricity capacity while lightening and thinning are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and more specifically relates to a backlight source, a display panel and a display device. Background technique [0002] In the field of liquid crystal display, the antistatic ability of the backlight source is very important. Such as figure 1 As shown, the existing backlight generally uses a metal backplane, and the metal backplane will be connected to the ground wire on the FPCA (Flexible Printed Circuit Assembly, flexible printed circuit) or PCBA (finished circuit board) through a conductive double-sided adhesive tape, and through the FPCA or PCBA The ground wire will discharge static electricity. Therefore, in addition to strong supporting capacity, the metal backplane will also play a good role in electrostatic shielding. When performing an ESD (Electro-Static discharge) test on the backlight, the metal backplane will preferentially attract static electricity and lead it aw...
