Problems solved by technology

When the backlight module 2 provides the display light source to the liquid crystal panel 1, it will inevitably pass through the lower polarizer 14, and it has been verified through experiments that the lower polarizer 14 will absorb more than 50% of the light provided by the backlight module 2, so that the backlight module 2 provides The utilization of the backlight is extremely low, resulting in increased energy consumption

Abstract

The invention discloses a polaroid for a liquid crystal display panel. The polaroid comprises a substrate (241) and reflecting film layers which are formed on the substrate (241) at intervals, and the reflecting film layers correspond to black matrixes (212) in the liquid crystal display panel. The invention further discloses the liquid crystal display panel with the polaroid. According to the polaroid for the liquid crystal display panel and the liquid crystal display panel with the polaroid, the reflecting film layers are arranged on the lower surface of the polaroid for the liquid crystal display panel, a part of backlight provided by a backlight module can be reflected back into the backlight module through the reflecting film layers, hence, the light absorptive amount of the polaroid is lowered, the backlight utilization rate of the backlight module is increased, and energy consumption is lowered.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a polarizer for a liquid crystal panel and a liquid crystal panel. Background technique [0002] With the development of the information society, people's demand for flat panel displays has grown rapidly. A Liquid Crystal Display (LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. The LCD mainly includes a liquid crystal panel for displaying images and a backlight module for providing a display light source to the liquid crystal panel. [0003] figure 1 It is a structural schematic diagram of a liquid crystal display in the prior art. refer to figure 1 , the liquid crystal panel 1 is set opposite to the backlight module 2 . The liquid crystal panel 1 includes an upper polarizer 11 , an upper substrate 12 , a lower substrate 13 and ...
