  • Publication number: 20110279420
    Abstract: A display is disclosed. The display comprises a panel, a data driver and a scan driver. The panel comprises pixels, data lines and scan lines. The data lines transmit data signals to the pixels, and the scan lines transmit scan signals to the pixels. The data driver provides the data signals, and the scan driver provides the scan signals. The scan driver comprises a shift register circuit. The shift register circuit comprises an i+1th stage carry shift register, an ith stage carry shift register and a jth stage buffer shift register. The ith stage carry shift register generates an i+1th start signal to start the i+1th stage carry shift register, so that the i+1th stage carry shift register generates an i+2th start signal. The i+1th start signal starts the jth stage buffer shift register to generate a jth output signal.

  • Publication number: 20110157918
    Abstract: A backlight module is provided in the present invention. The backlight module includes a light guide plate, a light source plate and a plurality of side-view lighting elements. The light guide plate comprises a light guide body being an integrally-formed single plate body and comprising a plurality of elongated grooves and a plurality of penetrated grooves. The penetrated grooves and the elongated grooves are collectively arranged on a surface of the light guide plate to separate the light guide plate into a plurality of light emitting regions. The side-view lighting elements arranged on the light source plate are attached to a side of the light guide body and respectively disposed for the penetrated grooves to illuminate corresponding light emitting regions.

  • Publication number: 20110122649
    Abstract: A method and a structure for improving the uniformity light emitted from a backlight module are provided. In accordance with the present invention, a plurality of optical microstructures are intermittently distributed on an LGP of a backlight module. Each of the microstructures further includes a plurality of optical sub-microstructures. The optical microstructures and the optical sub-microstructures are distributed on the LGP with varied distribution intensities in three dimensions, such that at where the optical microstructures and the optical sub-microstructures are distributed with a larger distribution intensities the LGP refracts and reflects more light, and at where the optical microstructures and the optical sub-microstructures are distributed with a smaller distribution intensities the LGP refracts and reflects less light. In such a way, by designing particular distribution intensities of the optical microstructures and the optical sub-microstructures, the light emitted from the LGP can be uniformed.

  • Publication number: 20110050464
    Abstract: A key structure having an improved light emitting efficiency is provided. The key structure includes a light guide plate, an isolation sheet, a circuit board, an elastic member, and a key cap sequentially disposed one on another in order. A circuit and a plurality of first electrical contacts are distributed on a top surface of the light guide plate. An optical structure is disposed at a bottom surface of the light guide plate. The isolation sheet has a light reflective surface facing the light guide plate. A light source emits a light into the light guide plate. The light is reflected by the optical structure to pass through the through holes configured at the isolation sheet, thus allowing more light outputting through the through holes, so as to improve the illumination of the key cap, and improve the light emitting efficiency.

  • Publication number: 20100232138
    Abstract: A light guide plate (LGP) having a sectional light guiding structure is provided. The LGP is integrally configured with first grooves extending from a first side of the LGP to a second side of the LGP, and second grooves extending from a third side of the LGP to a fourth side of the LGP. The first grooves intersect with the second grooves, thus dividing the first surface of the LGP into a plurality of light guiding sections. Light sources are disposed in the first grooves and/or the second grooves. A sequence of lighting the light sources is controlled for respectively controlling the light sources to project light into the light guiding sections, so that the light guiding sections are controlled to guide the light according to a predetermined sequence.

  • Patent number: 7615285
    Abstract: A fabrication method of an indium tin oxide (ITO) anode containing point nickel for an organic light emitting diode (OLED) to selectively light includes various processes of preparing an ITO substrate with an anode having plural point grooves, of forming a nickel film on the anode, and of grinding the nickel film to leave the point grooves fitted with nickel. Therefore, the nickel spots of the ITO anode are lit up earlier than the pure ITO anode when the OLED is turn on. Because the nickel spots have a lower resistance, current can aggregate in these spots collectively, reducing demerit of cross-talk happening often in a conventional passive OLED panel circuit. The structure of the OLED includes an ITO substrate with an anode provided point grooves deposited with nickel, a hole transport layer on the anode, and an electron transport layer on the hole transport layer.

  • Publication number: 20090223794
    Abstract: A light emitting key structure is provided. The key structure includes a base, a reflective sheet, a circuit board, an elastic member, a linkage mechanism, and a key cap sequentially disposed one on another in order. The reflective sheet is disposed on the base. The circuit board is made of a light guide material. At least one light source is bonded to a lateral side of the circuit board. The circuit board, together with the light source bonded to the lateral side thereof is disposed on the reflective sheet. The elastic member is directly coupled to the circuit board. The key cap is featured with a light transmission characteristic. Therefore, in operation, a light emitted from the light source can be directly guided into the circuit board, and then outputted from the light transmissive key cap, thus achieving the light emitting effect.
