Problems solved by technology

When the light board is bent, the distance between the LED pads or solders becomes smaller, and it is easy to make contact between the pads or solders of adjacent LEDs, further increasing the risk of short circuit
In addition, when the lamp board is bent, the LED is also prone to pad breakage and virtual soldering, resulting in dead lights

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0026] As mentioned in the background technology section, in the existing backlight module, the density of LEDs arranged on the lamp board is relatively high, especially when the lamp board is bent, the distance between adjacent LEDs is further reduced. figure 1 It is a structural schematic diagram of the existing flat light panel, figure 2 It is a schematic diagram of the structure of the existing lamp panel in the bending state, compared with figure 1 and figure 2 It can be seen that in the flat state, the d...

Abstract

The embodiment of the invention discloses a light board, a backlight module and a curved display device. The light board comprises a substrate basal plate, multiple light sources and an insulation structure; multiple bonding pads are arranged on the substrate basal plate; each the bonding pad comprises a first part and a second part; the light sources are electrically connected with the substratebasal plate through the bonding pads; orthographic projection of the first part in the plane, where the substrate basal plate is, is positioned in corresponding orthographic projection of the light source in the plane, where the substrate basal plate is; and orthographic projection of the second part in the plane, where the substrate basal plate is, is positioned in orthographic projection of theinsulation structure in the plane, where the substrate basal plate is. According to the light board in the embodiment of the invention, the short-circuiting problem due to the fact that bonding pads of adjacent light sources are easily contacted when the light board is curved can be solved; mutual insulation among the bonding pads is ensured; simultaneously, the insulation structure can be used for relieving bending stress of the bonding pads; and breakage of the bonding pads when the light board is curved is prevented.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a lamp panel, a backlight module and a curved display device. Background technique [0002] The backlight module is one of the key components of the liquid crystal display panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. A traditional backlight module is provided with a light board, and a uniform backlight is realized through light emitting diodes (light emitting diodes, LEDs) distributed on the light board and a light scattering structure. [0003] In the existing LED light board, LEDs are usually stamped on the light board, and then the light board is attached to the iron frame backboard. Moreover, in order to ensure the uniformity of the backlight of the backlight module, the density of LEDs is generally relatively high, and the distance between adjacent LEDs is re...
