Abstract: A display device includes a backlight module, a display panel, a prism film, a light-splitting layer, and a grating layer. The light-splitting layer splits light into a first backlight group and a second backlight group, wherein the two groups are inclined in different directions relative to a light-emitting surface of the backlight module. The grating layer allows the first backlight group to pass while blocking the second backlight group. The prism film has a plurality of prisms disposed facing the display panel. Each prism has a first surface and a second surface, wherein the angle between the first surface and the normal line to the light-emitting surface is greater than the angle between the second surface and the normal line to the light-emitting surface.

Abstract: Video receiving capabilities of participants and source capabilities are compared and conference capabilities for providing different resolutions, frame rates, bit rate, and number of streams are determined by maintaining a conference receiving capability list updated as number and capability of participants' changes. Preferred receiving capabilities of participants are also taken into account in determining conference characteristics based on comparison with allowed capabilities.

Abstract: A touch display device includes a display panel, a light guide plate, at least an invisible light emitting device, and a first light path converting device. The light guide plate includes a plurality of microstructures to reflect an invisible light generated by the invisible light emitting device such that the invisible light passes through the display panel, reaching the first light path converting device.

Abstract: A touch display device includes a display panel, a touch panel, a plurality of first light sources, a plurality of light sensors and at least one second light source. The display panel has a display surface. The touch panel is disposed above the display panel and includes a transparent part, a plurality of light guide parts configured to protrude from the surface of the transparent part thereby corporately forming a touch region on the surface. The first light sources and first light source is reflected by the light guide parts so as to emit above the touch region and be received by the light sensors. The second light source is configured to emit visible light beams, which is emitted out via the touch panel.

Abstract: A display device includes a backlight module, a display panel, and a prism film. The backlight module has a light-emitting surface and generates backlight along an average light-emitting direction that is inclined with respect to the light-emitting surface. The display panel is disposed above the light-emitting surface such that backlight from the backlight module passes through the display panel along the inclined direction. The prism film is disposed on one side of the display panel opposite to the backlight module, wherein the prism film has a plurality of prisms disposed side-by-side on one side of the prism film facing the display panel. An extending direction of the prisms at least partially traverses across the average light-emitting direction. Two sides of each prism are respectively a first surface and a second surface, wherein the first surface and the second surface are asymmetric and projection areas of the first surface and the second surface onto the prism film do not overlap.

Abstract: Video send and receive capabilities of participants are determined by the respective machines determining available combinations, as well as preferences for the receivers. Receiver capabilities are forwarded to the source for computation of negotiated video capabilities through a logic intersection of the determined capabilities based on desired number of streams and resolutions. If a resolution of a send capability exists within the receive capability, the highest frame and/or bit rate may be selected for transmission.

Abstract: A three-dimensional display apparatus and a backlight module thereof are provided. The display apparatus further includes a display panel disposed on the backlight module. The backlight module has a light guide plate, a plurality of microstructures, a first light source, and a second light source. The light guide plate has a bottom surface and a light emitting surface opposite to the bottom surface, wherein the microstructures are disposed on at least one of the two surfaces. The first light source is at a first corner of the light guide plate while the second light source is at a second corner opposite to the first corner. A first surface and a second surface of the microstructure define an orientation direction (or form a distribution direction) along or parallel to the diagonal line through the first and second corners.

Abstract: An optical touch-sensing liquid crystal panel including a backlight, a liquid crystal display panel, a first reflector, a second reflector and a plurality of photo sensors is provided. The liquid crystal display panel includes a pixel array and a plurality of output light-valves, wherein the output light-valves are located outside the pixel array. The first reflector is disposed above the output light-valves. The photo sensors are disposed under the second reflector. The output light-valves and the photo sensors are respectively turned on by turns. When each of the output light-valves is turned on, the invisible light provided by the backlight passes through the output light-valves, the invisible light is then reflected by the first reflector as well as the second reflector in sequence and is captured by the corresponding photo sensor.
