preparation example Construction

[0055] The working principle of the preparation process of the backlight module provided in this embodiment:

[0056] In the prior art, the FPC is installed on the plastic frame, and the plastic frame is embedded in the metal frame, wherein the metal frame, the plastic frame, the LED lamp and the light guide plate are arranged in sequence, and the FPC is located on the plastic frame, and the FPC occupies a certain width. Furthermore, the distance H2 between the LED light and the visible area is increased, and the FPC needs to bypass the LED light to connect to the motherboard, which will increase the distance H1 between the LED light and the metal frame tail frame to a certain extent, and the plastic frame is located between the LED light and the metal frame , which greatly increases the distance H1 between the LED lamp and the tail frame of the metal frame, thereby greatly increasing the distance H between the visible area and the tail frame of the metal frame.

Abstract

The invention discloses a backlight module, a preparation process thereof and a display device, and the preparation process comprises the steps that a metal frame which comprises a frame body and a sinking groove formed in the tail part of the frame body is prepared; a light guide plate assembly is installed in the metal frame, the light guide plate assembly comprises a light guide plate, an FPC connected with the light guide plate and an LED lamp arranged on the FPC, and the FPC is installed in the sinking groove. The narrow frame is small, the screen-to-body ratio is increased, and the visual effect is improved; the cost is low, the production efficiency is high, and the heat dissipation performance is good.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a backlight module, a manufacturing process thereof, and a display device. Background technique [0002] Narrow bezel technology is a higher-level development requirement after the basic development of liquid crystal display technology. Narrow bezel means that a larger viewing area can be obtained on a display surface of the same size and resolution. [0003] With the continuous development of LCD product technology, the competition in the liquid crystal display market is becoming increasingly fierce. Among them, the narrow frame of the liquid crystal display device can effectively increase the high screen ratio and improve the visual effect, especially to adapt to the large size of mobile display products in the existing market. screen trend. [0004] For example, the narrow frame of the backlight module commonly used in mobile phones has reached its limit. Howe...
