  • Patent number: 6781642
    Abstract: A transparent touch panel (TTP) comprising a fixed substrate of transparent resin, an adhesion layer disposed on the fixed substrate, an antireflection layer disposed on the adhesion layer, a first transparent conductive layer disposed on the antireflection layer, a second transparent conductive layer opposed to and spaced apart from the first transparent conductive layer, and a flexible transparent film disposed on the upper surface of the second transparent conductive layer. In one embodiment, rather than having a separate adhesion layer and antireflection layer, the adhesion layer may also serve as the antireflection layer, the rest of the above components remaining the same. The use of transparent resin in the TTP of the present invention reduces weight and increases resistance to breaking. The antireflection layer decreases the light reflection at respective boundary surfaces, thus increasing light transmittance.

    Abstract: A daylight readable LCD which may be used to communicate information as high contrast images (static or dynamic, color or monochrome) in bright ambient lighting conditions over a wide temperature range in direct sunlight. A contrast enhancement filter assembly is disposed at the interface between a backlit display and a user. The contrast enhancement filter assembly includes a triple bandpass contrast enhancement filter that preferably passes light efficiently in each of the red, green, and blue primary wavelengths and substantially absorbs all other wavelengths. Display contrast is increased because of the absorption of incident light having wavelengths that differ from the light produced by the internal backlight source within the display. This results in the display having a blacker background and enhanced purity of the color primaries. The display element is disposed generally behind the contrast enhancement filter assembly.

    Abstract: Applying layers of dielectric material to a reflective conductive surface of an integrated circuit, increases the reflectance of the surface. The layers of dielectric material alternate between high and low indices of refraction. To enable incident light waves to undergo a uniform phase change as the waves pass between the dielectric materials, the thickness of each of the layers of dielectric material is established such that each of the layers of dielectric material have a substantially equal optical thickness. As a result, when he dielectric layers reflect incident light waves, the reflected light waves constructively interfere to increase the reflectance of the surface of the integrated circuit.

  • Patent number: 6005651
    Abstract: In a display panel, a first substrate is opposed to a second substrate and interposing a liquid crystal/resin composite layer. If the display panel is a transmission type display, a film for absorbing light is formed on a black matrix and between pixel electrodes. If the display panel is a reflection type display, a film for absorbing light is formed between reflection electrodes. Further, a counterelectrode is made from a multi-layer film of dielectric films and a transparent electrically conductive film for preventing reflection. The film for absorbing light includes pigments which can absorb light modulated by the liquid crystal/resin composite layer. By using the display panel, a projection display system of high contrast and high brightness can be constructed.

  • Patent number: 5965916
    Abstract: A thin-film transistor structure having a storage-capacitor-on-gate and a black matrix for manufacturing a liquid crystal display is disclosed. A metal layer is deposited and patterned as a black matrix on a glass substrate of the thin-film transistor plate. An insulating layer having a contact hole for contacting the black matrix is formed over the surface of the black matrix and the substrate. An inverted thin-film transistor having a metal gate on the bottom is then fabricated on top of the insulating layer. The thin-film transistor controls an ITO pixel electrode of the liquid crystal display. A gate line including the metal gate of the thin-film transistor is formed over and above a space between two adjacent black matrixes. The gate line is connected to one of the two black matrixes by the contact hole. The other black matrix serves as a light shield element of the ITO pixel electrode.

  • Patent number: 5959762
    Abstract: A flexible panel is provided that is easily and conformingly applied to a curved display screen of a VDU to afford, in a lightweight manner, variably adjustable contrast enhancement of the VDU while simultaneously providing a decrease in the amount of ambient light reflected from the curved display screen. The flexible panel is a glass microsheet layered, on one side thereof, with an antireflection coating and, on the other side, with an electrochromic device. The electrochrmic device allows for variable adjustment of the contrast of the VDU as a function of the voltage applied across the electrochromic device. The flexible glass microsheet dually possesses the advantages of conventional rigid glass panels, such as excellent optical performance, high durability, capability of being coated with various optical coatings under extreme temperature, pressure and chemical conditions and the additional benfeit of physical flexibility.

  • Patent number: 5754262
    Abstract: A daylight readable LCD which may be used to communicate information as high contrast images (static or dynamic, color or monochrome) in bright ambient lighting conditions over a wide temperature range in direct sunlight. A contrast enhancement filter assembly is disposed at the interface between a backlit display and a user. The contrast enhancement filter assembly includes a triple bandpass contrast enhancement filter that preferably passes light efficiently in each of the red, green, and blue primary wavelengths and substantially absorbs all other wavelengths. Display contrast is increased because of the absorption of incident light having wavelengths that differ from the light produced by the internal backlight source within the display. This results in the display having a blacker background and enhanced purity of the color primaries. The display element is disposed generally behind the contrast enhancement filter assembly.
