Problems solved by technology

Therefore, the light generated by the light-emitting chip 110 is mainly emitted from the top of the package body 120, so that the light intensity directly above the package body is higher and the light intensity on both sides of the package body is weaker, which will cause a gap between adjacent light-emitting bodies 110a. A dark area is formed, wherein the dark area formed between adjacent luminous bodies 110a in the oblique direction is the most obvious (such as image 3 The dark area R1 shown), which leads to the appearance of the backlight module with a clear contrast between light and dark, and uneven light mixing

Abstract

A light source structure (300), a backlight module (400) and a display device (500). The light source structure (300) includes a substrate (310), multiple light emitting units (320) and multiple packaging structures (330). The light-emitting units (320) are arrayed on the substrate (310), and each light-emitting unit (320) has a central optical axis perpendicular to the substrate (310). The encapsulation structure (330) respectively and correspondingly covers the light emitting units (320). Each encapsulation structure (330) has a centerline perpendicular to the substrate (310). The central optical axis of the light emitting unit (320) is offset relative to the central line of the package structure (330) along the same direction.

Description

technical field [0001] The invention relates to a light source element, and in particular to a light source structure, a backlight module and a display device. Background technique [0002] A general direct-lit backlight module mainly includes a backplane, a plurality of light-emitting diodes and an optical film. The light emitting diodes are arranged in an array on the back plate, and the optical film is arranged above the light emitting diodes to mix the light generated by the light emitting diodes. [0003] Please refer to Figure 1 to Figure 3 ,in figure 1 depicts the existing light-emitting diode structure, figure 2 is a simulated ray tracing diagram using an existing LED structure, image 3 It is a simulation diagram of the mixed light effect produced by using the existing light-emitting diodes. In the existing light emitting diode structure 100 , the light emitting chip 110 is packaged in the middle of the package body 120 to form light emitters 110 a , and thes...
