Problems solved by technology

[0003] A display device using Mini LED is usually composed of a backplane, Mini LED, a diffuser plate, an optical film, a plastic frame, a liquid crystal panel, and a front frame, but the diffuser plate is prone to slight deformation due to its own gravity and the pressure of the film layer on it. , affects the OD (optical distance, optical distance) value, and also reduces the distance between the diffuser plate and the Mini LED
resulting in poor display

Abstract

The present application discloses a display device. The backlight module in the display device includes a back panel, a lamp panel, a diffuser plate and an optical film. The optical film is arranged between the display panel and the diffuser plate. The optical film The side facing the display panel is fully bonded to the display panel, and the side of the optical film facing the diffusion plate is fully bonded to the diffusion plate; the backlight module also includes a The plastic frame on the back plate and the supporting frame arranged on the plastic frame, the diffusion plate is arranged on the supporting frame and spaced apart from the lamp board. This application takes advantage of the inflexibility of the display panel to bond the display panel with the diffusion plate and the optical film, so that the easily bendable optical film and the diffusion plate will not bend and sag due to large size without support in the display area. In this way, poor display effect caused by bending deformation of the diffusion plate is prevented.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device. Background technique [0002] In recent years, Mini LED (Mini Light Emitting Diode) has been used as a backlight source in LCD (Liquid crystal displays, liquid crystal display) panels, which can significantly improve display quality such as contrast and brightness, thus attracting more and more market attention. The Mini LED backlight technology is to bind an LED (Light Emitting Diode, light-emitting diode) chip to a backplane with a driving circuit, and control the LED subregional lighting to achieve dynamic backlighting through the driving circuit. The more partitions the Mini LED backlight has, the more LED lights, and the finer the control of the backlight. By using this backlight technology, LCD can achieve a display quality with a thinner appearance, higher brightness, and high contrast ratio (to achieve pure black). . [0003] Display de...
