  • Publication number: 20140293168
    Abstract: A touch panel including a substrate, a plurality of sensor units, a decoration layer, first signal lines, second signal lines, and at least one conductive component is provided. The substrate has an operation region and a periphery region surrounding the operation region. The sensor units are located within the operation region for sensing a coordinate of a touch point. The decoration layer is located within the periphery region. The first and second signal lines and the conductive component are located within the periphery region and disposed on the decoration layer. The conductive component has a widen portion located between the first and second signal lines, and the widen portion has a line width greater than those of the other portions of the conductive component.

  • Patent number: 8641215
    Abstract: A display device with switchable viewing includes a backlight module and a display panel. The backlight module includes a light guide plate, first optical structures, a reflector, a first light source, and a second light source. The light guide plate includes a bottom surface, a light exit surface, a first light incident surface, and a second light incident surface. The display panel is disposed on the light exit surface. The first optical structures are disposed on the bottom surface and each includes a first inclined surface and a second inclined surface. The angle between the first inclined surface and the bottom surface is smaller than that between the second inclined surface and the bottom surface. Lights from the first light source and the second light source enter the light guide plate from the first light incident surface and the second light incident surface, respectively.

  • Patent number: 8511880
    Abstract: An edge type light source module has at least one middle light emitting region and edge light emitting region and includes a first edge type light emitting device and a second edge type light emitting device. If the middle light emitting region is a lighting region having a brightness value L1, the edge light emitting region adjacent to the lighting region is a light leakage region. The light leakage region has a predetermined brightness value L2, and a compensation brightness value L2? of the light leakage region satisfies L2?=L2?(L1*k1*R1), 0?k1?1, and 20%?R1?60%. If the edge light emitting region is a lighting region having a brightness value L3, the middle light emitting region adjacent to the lighting region is a light leakage region. The light leakage region has a predetermined brightness value L4, and a compensation brightness value L4? of the light leakage region satisfies L4?=L4?(L3*k2*R2), 0?k2?1, and 10%?R2?50%.
