Abstract

A collection complex piece comprises a first optical element, a second optical element and a plurality of cavities. The first optical element is provided with a first surface, a second surface which is opposite to the first surface and a plurality of first prisms which are positioned at the first surface. The second optical element is provided with a diffusion material and combined with at least one part of the first prisms. A plurality of cavities are formed between the first optical element and the second optical element. The collection complex piece can solve the problems of a plurality of optical elements, thicker thickness and long assembly time, etc., in the prior art, thereby reducing the production cost of the product.

Description

technical field [0001] The invention relates to an optical element, in particular to a light-collecting composite sheet with light-collecting function. Background technique [0002] In recent years, due to the development of display technology, conventional cathode ray display devices have been gradually replaced by liquid crystal display devices. In general, liquid crystal display devices have been applied to many types of electronic products, such as notebook computers, televisions, and desktop monitors. A general liquid crystal display device is mainly composed of a liquid crystal display panel (Liquid Crystal Display Panel) and a backlight module (Backlight Module). [0003] Please refer to figure 1 As shown, it is a schematic diagram of a conventional edge-lit backlight module. The edge-lit backlight module 1 includes a light source 11, a Light Guiding Plate (LGP) 12, a Lower Optical Diffusing Sheet 13, a Brightness Enhancement Film 14 and an upper Diffusion sheet (...
