Embodiment Construction

[0024] In order to better understand the present invention, the present invention will be further described below with reference to the accompanying drawings. In the drawings, the same symbols indicate the same components or structures.

[0025] refer to Figure 1a , Figure 1a An exemplary surface light source device of the present invention is shown. The surface light source device includes a luminous body 106 , upper and lower layers of substrates 102 , 101 and a plurality of tiny convex hulls 104 . Wherein, the upper and lower substrate layers 102, 101 are located on the XZ plane. The substrate layers 102 and 101 are made of optically transparent materials, which can be a single layer or composited of multiple layers of optically transparent materials. Suitable substrate materials include polymethyl methacrylate (PMMA), polyphthalate (PC), PET, glass, acrylic adhesives, and the like. The thickness of the lower substrate layer 101 is preferably 100 microns to 3 mm, more ...

Abstract

The invention discloses a front area light source device, including a luminophor, and an upper base material layer and a lower base material layer made of a transparent optical material, and a plurality of tiny convex hulls. The area light source device can effectively increase the number of light rays which reach an observer through reflection of a display frame of a display, restrains the numberof light rays which reach an observer without being reflected by the display frame, so that display frames are still clear to see under a condition without ambient light.

Description

technical field [0001] The present invention relates to a surface light source, in particular to a front surface light source device that can be placed above the display panel of a display and on the same side of the display panel as the observer, and a reflective display device comprising the front surface light source device . Background technique [0002] Display technology has developed rapidly in recent years. Liquid crystal displays (LCDs) with high resolution and high color gamut, and OLED displays, which are gradually adopted by many mobile phone brands, can be seen everywhere. But these devices need to use a backlight or pass an electric current through the light-emitting material to make the display visible. When the observer is in an environment with strong light, such as under sunlight, the display device must increase the brightness to overcome the influence of the reflected light on the surface on the display screen. As we all know, the higher the brightness ...
