Special-shaped display screen and backlight plate thereof

Abstract

The invention belongs to the technical field of lighting device or its system functional characteristics or parts thereof, and particularly discloses a special-shaped display screen and backlight plate thereof. The special-shaped display screen and backlight plate thereof comprises a frame, wherein the frame is provided with a reflector, a light guide plate, a lower diffuser, a lower prism, an upper prism, an upper diffuser and a liquid crystal panel are arranged from bottom to top. A protective glass is fixedly arranged on the upper end surface of the frame, a gap is reserved between the protective glass and the liquid crystal panel, a light emitting diode is arranged between the light guide plate and the frame, a heat absorption pipe is arranged in the frame, a heat dissipation pipe is arranged on the outer wall of the frame, a first liquid inlet pipe and a first liquid outlet pipe are arranged between the heat dissipation pipe and the heat absorption pipe, a heat supply pipe is arranged in the frame, a second liquid inlet pipe is arranged between the heat supply pipe and the heat dissipation pipe, a second liquid outlet pipe is arranged between the heat supply pipe and the heatabsorption pipe, a liquid medium is filled in the heat radiation pipe, the heat absorption pipe and the heat supply pipe, and a driving mechanism is arranged in the heat dissipation pipe. The purposeof the special-shaped display screen and backlight plate thereof is to solve the problem that water mist can hardly be removed due to the small gap after the water vapor enters the gap between the protective glass and the liquid crystal panel.

Description

technical field [0001] The invention belongs to the technical field of functional features or components of a lighting device or its system, and specifically discloses a special-shaped display screen and a backlight panel thereof. Background technique [0002] Since liquid crystal materials were discovered by scientists, liquid crystal materials have been widely used in all walks of life, especially in the field of electronic display, but because liquid crystal materials cannot emit light by themselves, they need backlight panels to provide light sources, so the function of backlight modules is to supply sufficient The light source with uniform brightness and distribution enables the LCD to display images normally. [0003] At present, in the fields of smart phones, smart watches, and tablet computers, LCD screens are the most used screens. During the screen assembly process, in order to protect the LCD panel, a layer of protective glass is usually installed on the top of th...
