Abstract

The present invention discloses a system for displaying images, comprising: a light source; a panel including an active area and a peripheral area; a light guide being located at one side of the light source and under the panel, the light guide having a first side facing the panel and a second side opposite to the first side; and a plurality of optical foils, each foil disposed on the first or second side of the light guide, wherein at least one of the optical foil has a hotspot-reducing area in the peripheral area in order to reduce or eliminate a hotspot in front of the light source, wherein the hotspot-reducing area is a cut-out area, a covered area, or combinations thereof.

Description

technical field [0001] The present invention relates to an electronic device, a light emitting system, and a display image system, in particular to an electronic device, a light emitting system, and a display image system with an optical film with a hot spot reduction area, so as to reduce or eliminate system hot spots. Background technique [0002] figure 1 It is a schematic top view of an existing system 2 for displaying images. figure 2 display edge figure 1 Sectional view of line 1-1'. The existing system 2 includes a light source 101 , a display panel 201 including an active area AA and a peripheral area PA, prisms 203 and 205 , a diffuser 207 , a light guide 209 , and a reflector 211 . exist figure 1 In the system 2 of , when the light source 101 is activated, a hot spot 102 is usually generated. The light source 101 can be an LED. Besides that, in figure 1 In the example shown, this prism 203 only shows an optical film. The light guide 209 is located on one s...
