Problems solved by technology

Therefore, before the backplane and the reflector are glued, it is necessary to repeatedly move the reflector to the precise position, resulting in excessive man-hours for the entire process
At the same time, during the moving process, the adhesive between the backplane and the reflective sheet is easily contacted, resulting in reduced adhesion

Embodiment 2

[0042] The general structure of the second embodiment is similar to that of the first embodiment, and no additional description is given. This embodiment only describes the differences between the second embodiment and the first embodiment in detail.

[0043] like image 3 Said, the secondary optical lens includes a main body 104A and a positioning portion 104B, the positioning portion 104B protrudes from the outer periphery of the main body 104A of the secondary optical lens, and the first type of through hole is tightly connected to the positioning portion 104B. on the positioning part 104B. image 3 It is given that there are three positioning parts on each prism, which is not for limitation, and one or more positioning parts can be provided. For example, the main body is circular with a maximum outer diameter of 16 mm, and at least one positioning portion protrudes from the main body, for example, the dimension from the central axis of the main body to the outermost p...

Embodiment 3

[0049] This embodiment provides a display device, and the display device may be a television or the like. The display device includes the backlight modules provided in Embodiment 1 and Embodiment 2, and naturally has the relevant advantages mentioned in the embodiments, so no further discussion will be made here again.

Abstract

The invention discloses a direct type backlight module which comprises a back plate, a light emitting diode light bar and reflector plates, wherein the light emitting diode light bar is fixed on the back plate and comprises a printed circuit board and an LED light, a secondary optical lens is arranged on the LED light and is fixed on the light emitting diode light bar or the back plate, the reflector plates are laid on the upper portion of the back plate or the upper portion of the light emitting diode light bar, through holes are formed in positions, corresponding to the LED light, of the reflector plates, and the inner edge of at least one through hole is tightly locked on the secondary optical lens. The invention further discloses a display device comprising the backlight module and a television.

Description

technical field [0001] The invention relates to the display field, in particular to a direct-lit backlight module, a display device, and a television. Background technique [0002] With the development of social economy, liquid crystal display (LCD) panels are widely used in electronic equipment. Since the LCD panel itself does not have the function of emitting light, a backlight module must be provided under the liquid crystal display panel to provide the surface light source required by the liquid crystal display panel. Backlight module is one of the most important components in liquid crystal display, which directly affects the quality of liquid crystal display. Common backlight modules can be divided into edge-type backlight modules and direct-type backlight modules. As the name implies, the light source of the side-type backlight module is set at the backlight group bottom. [0003] The direct type backlight module includes a back plate 101, on which a plurality of l...
