A backlight assembly includes a plurality of light sources generating light, a light guide plate and a prism sheet. The light sources include first light sources and second light sources having a different emitting angle from the first light sources. The light guide plate includes an incident surface to which the light is incident, an exiting surface extended from the incident surface, opposing to the incident surface and emitting the incident light and an opposing surface extended from the exiting surface. The opposing surface meets the exiting surface at a substantially straight line. The prism sheet converts the emitted light from the light guide plate.

To provide a display device including a protection circuit having a thin film transistor which has small size and high withstand voltage. In the protection circuit of the display device, a thin film transistor is used in which an amorphous semiconductor layer, a microcrystalline semiconductor layer, a gate insulating layer which is in contact with the microcrystalline semiconductor layer, and a gate electrode layer overlap with each other. Since current drive capability of the microcrystalline semiconductor layer is high, the size of the transistor can be made small. In addition, the amorphous semiconductor layer is included, so that the withstand voltage can be improved. Here, the display device is a liquid crystal display device or a light-emitting device.

A display apparatus includes, on a substrate, an area in which a plurality of constituents each including a light-emitting device and a device control circuit for controlling current passing through the light-emitting device is disposed, a common interconnecting line disposed to surround a periphery of the area, a terminal portion for permitting electrical connection to an external circuit, and a wiring lead-out portion for electrically connecting the common interconnecting line to the terminal portion. The light-emitting device is disposed, on the substrate, between a lower first electrode and an upper second electrode. The first electrode is electrically connected to the device control circuit, and the second electrode is electrically connected to the common interconnecting line through a contact hole. The common interconnecting line disposed along a side of the area most distant from the wiring lead-out portion has a narrower width than a width of the common interconnecting line disposed along a side of the area closer to the wiring lead-out portion.

The present invention relates to an organic electroluminescent display, including a substrate, a set of anodes, an organic functional layer, a set of cathodes and a packaging sheet, wherein a set of electrode leads are disposed on the packaging sheet for electrical connection with a control circuit of the display, and the electrode leads includes a set of anode leads and a set of cathode leads which are electrically connected with the corresponding anodes and cathodes on the substrate, respectively. The present invention further relates to a double-sided organic electroluminescent display having the above features.

A signal line drive circuit according to the present invention has: a latch circuit which latches digital pixel data; a D/A converter which converts a latch output from the latch circuit into an analog video signal; an AMP which amplifies the analog video signal converted by the D/A converter; and a signal selection circuit which selects a signal line to which the analog video signal amplified by the AMP is supplied. The AMP has: an odd number of inverters which are cascade-connected; capacitor elements which are respectively connected between stages of the inverters and between an input terminal of the inverter on a first stage and an output terminal of the inverter on a last stage; a first power supply line which supplies a power supply voltage to the inverter on the first stage; and a second power supply line which supplies a power supply voltage to inverters other than the inverter on the first stage. The accuracy of the AMP can be improved by separating the power supply line for only the inverter on the first stage.

Embodiments provide a video camera that can be configured to compress video data in a manner that achieves a targeted output size in a computationally efficient manner The video compression systems and methods can be used with DCT-based compression standards to include a rate control aspect. The rate controlled video compression methods can be configured to compress video data in, real time and/or using a single pass. During compression of video data, the video compression systems and methods can modify compression parameters to achieve a targeted file size while maintaining relatively high visual quality of the compressed images.

A static display system mounted to an underground tunnel wall exhibits movie style images to passing passengers. Trip means control lighting of each image as the passenger carriages pass by. Extended lighting circuit means control duration of the lighting of each image for optimum contrast and viewability from the passengers point of view. The images are displayed by film reel means attached to framework means having guides which simplify changing the reels. Each reel segment contains about five image frames.

An external electrode fluorescent lamp has external electrodes at opposite ends. The portions provided with the external electrodes are bent so that their axes are orthogonal to the axis of a light emitting sections. A conventional external electrode fluorescent lamp is not bent in its portions provided with external electrodes. Since the external electrodes of the external electrodes fluorescent lamps serve concurrently as holding sections for the fluorescent lamps the axial length is made greater than the outer diameter so as to provide sufficient strength. The width of the frame section of the fluorescent lamp of the invention when mounted on a backlight unit is smaller than the width of the frame section of conventional fluorescent lamp. Therefore, the effective light emitting area of the backlight unit can be enlarged.

Reducing a frame size in a memory for a receiver includes compressing a first analog television picture frame, storing the compressed frame in the memory, decompressing the compressed frame from the memory, obtaining a second analog television picture frame. The first frame includes a first set of pixels that further include at least one of Red/Green/Blue (RGB) samples and, the second frame includes a second set of pixels. Each of the first set of pixels of first frame being decompressed are compared with the corresponding second set of pixels of second frame to obtain an alpha (α) factor. A Signal to Noise Ratio (SNR) and a motion per pixel of the first set of pixels and the second set of pixels are compared. Each of a pixel is displayed based on the α factor.

A backlight module and a display device are disclosed. The backlight module includes a light guide plate, a light source, and a bracket. The bracket includes a backplate and a bending portion disposed along a peripheral side of the backplate. An accommodation groove is formed in a space between the backplate and the bending portion and is configured to place the light guide plate. A first groove is disposed on an inner side of the bending portion facing and exposed to the light guide plate, and the light source is disposed in the first groove.

A photoelectric encoder includes: a scale; a detection head; fibers through which light that is to be irradiated on the scale and light reflected by the scale propagates; first and second cables each having a space in which the fibers are partially disposed; and a case that encloses a light source that supplies light to one of the fibers and a light-sensitive element that receives the reflected light propagating through the others of the fibers and converts the received light into an electric signal. The first cable, the second cable, and the case are disposed in this order in the direction of propagation of the reflected light. The positions of the fibers are fixed relative to one another inside the first cable in the direction orthogonal to the direction of length of the fibers and variable relative to one another inside the second cable in the orthogonal direction.
