Shading energy-saving type display panel for TPC (transmit power control) model

Abstract

The invention discloses a shading energy-saving type display panel for a TPC (transmit power control) model. The shading energy-saving type display panel for the TPC model comprises a backlight paneland an LCD (liquid crystal display), wherein the backlight panel comprises a backing plate, a light bar, a reflective sheet, a light guide plate, a plastic frame and a film layer; the plastic frame isdesigned along four sides of the backing plate; clamp slots are formed in the four side walls of the backing plate; a plastic frame buckle point is designed on the light incident side of the plasticframe, a backing plate clamp slot is formed in the light incident side of the backing plate, the light incident side of the plastic frame is clamped into the backing plate clamp slot through the plastic frame buckle point in an embedded manner, plastic frame clamp slots are formed in the other three sides except the light incident side of the plastic frame, backing plate buckle points are formed on the other three sides except the light incident side of the backing plate, the light incident side of the plastic frame is clamped in the backing plate clamp slot through the plastic frame buckle point in an outer inlaid manner, and the film layer is laid on the light guide plate. Compared with a full outer-inlaid structure, the shading energy-saving type display panel for the TPC model has thecharacteristics that working efficiency is just reduced by about 10%, however, the overall optical brightness can be increased by about 150-250 cd / m<2>, and a fluctuating value of optical uniformity is smaller than 5%.

Description

technical field [0001] The invention relates to a new material energy-saving technology, in particular to a light-shielding energy-saving display panel for TPC models. Background technique [0002] The composition and working principle of liquid crystal display: In terms of the structure of liquid crystal display, whether it is a notebook screen or a desktop liquid crystal display, the liquid crystal display screens used are all layered structures composed of different parts. The liquid crystal display consists of two plates, about 1mm thick, separated by a uniform interval of 5um containing liquid crystal material. Because the liquid crystal material itself does not emit light, there is a backlight panel (or uniform light panel) and a reflective film on the back of the LCD screen. The backlight panel is composed of fluorescent substances and can emit light. Its main function is to provide a uniform backlight. [0003] With the development of the times, user experience requ...

Problems solved by technology

[0003] With the development of the times, user experience requirements are also gradually increasing, requiring high brightness, high color gamut, and high contrast. The above-mentioned development of display technology and user experience requirements have also brought about a significant increase in power consumption and heat generation. Therefore, it is necessary Develop backlight displays with low energy consumption and high light transmittance. Among them, in the existing liquid crystal display devices, the luminous quality of the backlight module will directly affect the picture quality of the liquid crystal display
