20140049778 | Device And A Method For Detecting A Transmittivity Spectrum Of A Light Guiding Plate - A detect device and a detect method for transmittivity spectrum of the light guiding plate are provided. The detect device comprises a mixing cavity unit for providing a linear light source with continuous spectrum to a light guiding plate to be detected; a light guiding plate placing unit located at a side of the mixing cavity unit, on which the light guiding plate to be detected is disposed to receive light from the mixing cavity unit; and a detecting lens disposed above the light guiding plate placing unit for detect the spectrum. | 02-20-2014 |
20140063846 | SURFACE LIGHT SOURCE DEVICE AND EDGE-LIT TYPE BACKLIGHT MODULE - The invention provides a surface light source device and an edge-lit type backlight module. The surface light source device comprises: a luminant, a bottom reflector plate, a light leaking plate and a plurality of side reflector plates, wherein the bottom reflector plate and the plurality of side reflector plates form a light guide box with an upper opening, the luminant is disposed on at least one of the plurality of side reflector plates, the light leaking plate is disposed in the upper opening of the light guide box, such that light from the luminant is transformed into an exiting surface light via the light leaking plate. | 03-06-2014 |
20140104884 | LIGHT GUIDE PLATE, AND METHOD AND MOLD FOR MANUFACTURING THE SAME - The present invention provides a light guide plate and a method and a mold for manufacturing the same. The light guide plate comprises at least one incident surface, an exiting surface and a bottom surface, the exiting surface and bottom surface being disposed facing to each other and both being connected to the incident surface, the light guide plate having a cavity formed therein, wherein light incident from the incident surface exits the exiting surface after refracted and/or reflected by the cavity. With the light guide plate, light energy loss can be reduced and brightness of pictures can be improved. | 04-17-2014 |
20150309318 | Light Concentrating Film and Display Device - The present disclosure provides a light concentrating film and a display device. The light concentrating film has a planar shape, and includes multiple light concentrating units which are connected to each other so as to concentrate the incident light on a light incoming side of the light concentrating film at the light outgoing side of the light concentrating film. The display device of the present disclosure includes a display panel and the light concentrating film of the present disclosure, and the light outgoing side of the light concentrating film faces a light incoming side of the display panel. | 10-29-2015 |
20150355407 | BACKLIGHT SIMULATING DEVICE - The present invention provides a backlight simulating device comprising a light source simulating portion, an optical component simulating portion, a first distance measuring unit, and a second distance measuring unit. Multiple movable light-emitting members are equipped to the light source simulating portion. The optical component simulating portion is disposed adjacent to a light-emitting surface of each of the light-emitting members. The optical component simulating portion includes a light guide panel whose position can be changed relative to the light-emitting members. The first distance measuring unit acquires a distance between adjacent two of the light-emitting members. The second distance measuring unit acquires a distance between the light-emitting members and the light guide panel. | 12-10-2015 |
20160035946 | LIGHT EMITTING DIODE PACKAGE STRUCTURE, BACKLIGHT MODULE AND DISPLAY DEVICE - The present disclosure provides a light emitting diode (LED) package structure, a backlight module and a display device, and relates to the field of display technologies. The LED package structure includes an encapsulation housing and an LED chip encapsulated in the encapsulation housing. The encapsulation housing is a polyhedron which includes at least one inclined plane. One inclined plane of the encapsulation housing is a light exiting surface of the LED package structure. | 02-04-2016 |
