Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] see figure 1 , The first embodiment of the present invention provides a brightness enhancing sheet 10, which is used to be attached to the surface of the display screen to increase the brightness of the display screen. The brightness enhancement sheet 10 includes a substrate 12 and a plurality of microlenses 14 in the shape of a regular quadrangular pyramid arranged on the surface of the substrate 12. The plurality of microlenses 14 have the same shape and size, and are arranged in a determinant on the surface of the substrate 12. Adjacent microlenses 14 have intervals between them and each interval is equal. It can be understood that adjacent microlenses 14 can also be closely arranged.

[0014] The substrate 12 and the plurality of microlenses 14 are generally made of plastic materials, such as polymethylmethacrylate (PolymethylMethacrylate, PMMA) ...

Abstract

The invention relates to a display, comprising a display screen and a brightening slice. The display screen is provided with a surface for emergent rays; the brightening slice consists of a transparent substrate with two opposite surfaces, one surface is provided with a plurality of square pyramid-shaped micro lenses, and the other surface is attached on the surface of the display screen for emergent rays. The multiple square pyramid-shaped micro lenses can destroy the total reflection condition of the display screen emergent rays to outside, so that more rays can be emerged to the outside, thus increasing the emergent ray brightness of the display screen.

Description

technical field [0001] The invention relates to a display, in particular to a display with a brightness enhancing sheet. Background technique [0002] With the advancement of science and technology, various types of displays have been widely popularized, such as liquid crystal displays used in mobile phones and LCD TV screens (“SOS liquid crystal TV display”, Electron Devices Meeting, 1974International, pp.5-5, Volume 20, 1974), Light-emitting diode displays are used in large-scale display boards, etc. [0003] Most of the displays include a substrate for presenting images to the outside. The substrate is generally made of transparent glass or plastic material. The light inside the display is emitted from the transparent substrate to achieve the purpose of display. However, the refractive index of the substrate material is greater than that of air, so part of the light is lost in the substrate due to total reflection, which affects the light output brightness of the display...
