Embodiment Construction
[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0041] In the related art, a display device includes a display panel and a backlight module. Taking a direct-type backlight module as an example, the backlight module includes a backplane and an LED light bar disposed on one side of the backboard. The brightness of the LED light bar determines the backlight. The brightness of the module further determines the display effect of the display device. In the existing LED light bar production proce...

Abstract
The invention discloses a preparation method of a flexible light bar, the flexible light bar and a display device. The preparation method of the flexible light bar comprises the steps that a flexible reflector plate is provided, and the flexible reflector plate is made of polyethylene glycol terephthalate and titanium dioxide; forming a circuit structure on the flexible reflector plate; fixing a plurality of light-emitting chips on the circuit structure, and electrically connecting the plurality of light-emitting chips with the circuit structure; and forming a packaging layer covering each light-emitting chip on the flexible reflector plate. According to the embodiment of the invention, the circuit structure is directly arranged on the flexible reflector plate, when the circuit structure is powered on, the light-emitting chip emits light, and the flexible reflector plate can reflect light emitted by the light-emitting chip to the flexible reflector plate, that is, the circuit board provided by the embodiment of the invention has a light reflecting effect, so that compared with an existing LED light bar, the circuit board has the advantages that the cost is reduced; according to the flexible light bar, the circuit board does not need to be coated with a reflective coating, the process step of coating the reflective coating is omitted, the production process of the flexible light bar is simplified, and the production efficiency of the flexible light bar is improved.
Description
technical field [0001] The present application belongs to the field of display devices, and in particular relates to a preparation method of a flexible light bar, a flexible light bar and a display device. Background technique [0002] Liquid crystal display devices are widely used in electronic display equipment. Most of the display devices on the market are backlit liquid crystal displays, which include a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, it needs to use the light source provided by the backlight module to display images normally. Therefore, the backlight module has become one of the key components of the liquid crystal display device. According to the different incident positions of the backlight source, the backlight module is divided into two types: edge-type backlight module and direct-type backlight module. Currently, the direct-type backlight module is widely used in the market. The...
