Edge-lit backlight module and its light source and display panel

Abstract

The present invention discloses a side light type backlight module set, a light source thereof and a display panel. The light source of the side light type backlight module set comprises a plurality of light emitting units; the light emitting units are arranged in a first direction; each of the light emitting units comprises a bracket, a chip carrying component, a light emitting chip and a package cover plate, wherein the package cover plate and the chip carrying component are arranged oppositely, and the light emitting chip is arranged on the carrying plane of the chip carrying component; the light of the light emitting unit is emitted through the package cover plate; a plane where the outer surface of the package cover plate is located is parallel to the first direction; the plurality of light emitting units comprises first light emitting units; and in the first light emitting unit, a tilt included angle is formed between the carrying plane of the chip carrying component and the first direction. The light source of the side light type backlight module set provided by the invention can be applicable to a side light type backlight module set with a light guide plate of which the left corner and right corner are missing, and with the light source adopted, the problem that shadows exist at the left corner and right corner of the lower frame of the display region of a display panel can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an edge-lit backlight module, a light source thereof, and a display panel. Background technique [0002] figure 1 It is the structural representation of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) in the prior art, as figure 1 As shown, in the existing display panel technology, it is necessary to design an IC (Integrated Circuit, integrated circuit) 1 to drive the display panel display, and usually IC1 is connected to the gate line and the data line on the flexible circuit board 3 and the TFT substrate 2 respectively. , IC1 is welded on the TFT substrate 2 through conductive glue, and IC1 is usually arranged on the lower frame of the display panel. At present, as the industry has higher and higher requirements for the screen-to-body ratio index, the IC1 installed in the lower frame restricts the narrowing ...

Problems solved by technology

In order to match the notched corner of the TFT, the relative position of the light guide plate in the backlight module needs to be set with a notched corner of the same size. According to the traditional design, figure 2 It is a structural schematic diagram of another TFT-LCD in the prior art, such as figure 2 As shown, because of the impact of the missing corner of the light guide plate 4 in the backlight module, taking the light source of the backlight module using LED (Light Emitting Diode, light emitting diode) as an example, as shown in figure 2 As shown in the middle area Q, some LED5 will exceed the shape of the backlight, resulting in light leakage

[0004] In order to solve the above problems, there are solutions to reduce the number of LEDs in the light source in the prior art, image 3 It is a structural schematic diagram of another TFT-LCD in the prior art, such as image 3 As shown, reducing the number of LEDs will lead to a larger distance between the edge LED5 and the side of the display area AA. Due to the limitation of the light emitting angle of the LED5, in this solution, a dark shadow will be generated at the position Z corresponding to the missing corner of the backlight module, and then on the display The position Z corresponding to the left and right corners of the lower border of the area will produce shadows, which will affect the display effect of the display area
