Problems solved by technology

Indirectly, by omitting the diffusion plate for printing dots, the thickness of the protective glue should be preserved, avoiding the inconsistent thickness of the protective glue caused by thinning the protective glue, and also improving the problem of uneven distribution of light and dark on the screen

Embodiment Construction

[0052] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other elements exist between two elements.

[0053] As used herein, "about," "approximately," or "substantially" includes stated values ​​and averages within acceptable deviations from a particular value as determined by one of ordinary skill ...

Abstract

The invention provides a backlight module. The backlight module comprises a substrate, a plurality of light-emitting elements, a protective layer and a plurality of first lattice points, the light-emitting element is arranged on the substrate. The protection layer is arranged on the substrate and the light-emitting element, the protection layer is provided with an upper surface and a lower surface opposite to the upper surface, and the upper surface is a plane. And the first lattice points are arranged on the protective layer and respectively cover the light-emitting elements, and the vertical projection area of each first lattice point on the substrate is larger than that of each light-emitting element on the substrate, so that the thickness of the backlight module is reduced, and lattice point alignment procedures are reduced.

Description

technical field [0001] The present disclosure relates to a backlight module. Background technique [0002] Generally speaking, the light emitting elements of the direct type backlight module are mostly light emitting diodes (light emission diodes, LEDs). Since the light intensity directly above the LED is the strongest, currently the dots are printed on the diffuser plate to weaken the light intensity directly above the LED to achieve uniform brightness of the screen. [0003] With the demand for lighter and thinner products, the thickness of each component is expected to be as thin as possible. Since the current dots need to be printed on the diffuser plate, the thickness of the backlight module remains high. Furthermore, the diffuser plate printed with dots must be accurately aligned with the LEDs during assembly to play the function of shielding the light intensity directly above the LEDs. As long as there is a slight deviation in the alignment, uneven brightness and da...
