The first support section allows displacement of the light guide plate in the second direction while limiting displacement of the light guide plate in the first direction. The second support section allows displacement of the light guide plate in the first direction while limiting displacement of the light guide plate in the second direction. | 10-09-2014 |
| 20140321162 | ILLUMINATION CONTROL - The methods, devices, and/or compositions described herein can used to reduce variations, such as spatial and temporal variations, in luminance intensity. Luminance variation is reduced by varying some aspect of transmittance with respect to the intensity of light. | 10-30-2014 |
| 20140340937 | FRAME AND BACKLIGHT MODULE HAVING SAME - A frame for a backlight module includes a first strip, a second strip, a third strip, and a fourth strip connected end to end in sequence to cooperatively enclose an interior of the frame. The first strip, the second strip, the third strip, and the fourth strip each include an inner surface facing the interior of the frame. A number of microdots are formed on the inner surface. | 11-20-2014 |
| 20150036386 | ILLUMINATION DEVICE HAVING A TAPERED LIGHT GUIDE - This disclosure provides systems, methods and apparatus for illumination devices. In one aspect, an illumination device having a longitudinal axis includes a light source and a light guide. The light guide has a peripheral edge, a transmissive illumination surface, a center portion, and an upper surface. The transmissive illumination surface is oriented perpendicular to the longitudinal axis and disposed between the center portion and the peripheral edge. The upper surface is oriented relative to the illumination surface to define an angle α therebetween. In some implementations, the angle α can be greater than 15 degrees, for example. | 02-05-2015 |
| 20150316710 | BUFFER ELEMENT AND MANUFACTURING METHOD THEREOF, BACKLIGHT MODULE, AND DISPLAY DEVICE - A buffer element and a manufacturing method thereof, a backlight module, and a display device are disclosed. When the buffer element is applied to the backlight module, the problem caused by thermal expansion of the light guide plate can be effectively solved without needing to reserve a gap in the backlight module, the relative movement of the light guide plate is avoided and the optical quality of the backlight module is improved. The buffer element comprises a buffer body, wherein the buffer body comprises a curable adhesive, and a negative thermal expansion material dispersed in the curable adhesive. | 11-05-2015 |
| 20150331179 | BACKLIGHT AND DISPLAY DEVICE - The present disclosure discloses a backlight, which includes a rubber frame, a light guide plate and a membrane disposed on the light guide plate. The membrane has at least one positioning hole defined therein; the rubber frame includes an elastic connecting part disposed thereon, and the elastic connecting part engages with the positioning hole to fix the membrane. The present disclosure also discloses a display device. | 11-19-2015 |
| 20160077277 | Light Core, in Particular for Flat Lighting Systems - The invention relates to a light core ( | 03-17-2016 |
| 20160091658 | BACKLIGHT MODULE AND DISPLAY DEVICE - The present disclosure provides a backlight module and a display device. The backlight module includes a back plate, a light-guiding plate arranged on the back plate, and an elastic member arranged between a lateral edge of the back plate and a corresponding lateral edge of the light-guiding plate. The elastic member includes a body connected to the back plate, and a positioning member connected to the body and positioning the light-guiding plate. | 03-31-2016 |
| 20160187572 | Optical Unit and Display Apparatus - Provided is an optical unit which includes a light guide plate configured to emit light made incident thereon through a light incident side surface from one surface thereof, and a reflection sheet disposed to face the light guide plate, wherein the reflection sheet has a projection piece which protrudes with respect to a surface of the reflection sheet on one edge thereof. The projection piece is held with being in surface contact with any one side surface of the light guide plate, thereby the reflection sheet is held so as to face the light guide plate. | 06-30-2016 |
