  • Patent number: 9030631
    Abstract: The present disclosure provides a liquid crystal displaying panel, which includes a first substrate having a displaying area and a sealant-coating area surrounding the displaying area and a light-blocking layer arranged between the displaying area and the sealant-coating area. The light-blocking layer can absorb and block ultraviolet light to prevent the ultraviolet light from affecting the liquid crystal layer. Additionally, the light-blocking layer and the pixel electrode layer are formed in the same process, that is, the light-blocking layer is simultaneously formed when the pixel electrode layer is formed. A thickness of the light-blocking layer is equal to that of the pixel electrode layer. Since the thickness of the light-blocking layer is equal to that of the pixel electrode layer, the pixel electrode layer and the light-blocking layer can be formed in the same process, which simplifies the manufacturing process of the light-blocking layer and the needed equipment.

  • Patent number: 8994908
    Abstract: In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.

  • Patent number: 8988646
    Abstract: A method for adjusting an amount of liquid crystal in a liquid crystal display (LCD) device includes injecting a liquid crystal into a liquid crystal receiving space. The liquid crystal receiving space is disposed between a first substrate, a second substrate that faces the first substrate, and a sealing member interposed between the first and second substrates. The method for adjusting an amount of liquid crystal in a liquid crystal display (LCD) device further includes reducing a thickness of the sealing member at a predetermined portion of the sealing member to form a repair region, and pressurizing the liquid crystal to break the sealing member at the repair region to discharge some of the liquid crystal from the liquid crystal receiving space, so as to adjust the amount of the liquid crystal in the liquid crystal receiving space. The method for adjusting an amount of liquid crystal in a liquid crystal display (LCD) device also includes resealing the broken repair region of the sealing member.

    Abstract: An electronic device may have a display such as a liquid crystal display. The display may include a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. The thin-film transistor layer may be provided with capacitive touch sensor electrodes. Wide metal lines on the thin-film transistor layer may be used to inhibit parasitic capacitances during touch sensor mode. The color filter layer may include a layer of black masking material that surrounds the active display area.

  • Patent number: 8976527
    Abstract: The described embodiment relates generally to the manufacture of display assemblies. More particularly the use of alternative back plates for a display assembly is discussed. By using a printed circuit board (PCB) in lieu of a metal backer heat can be evenly spread across the backer by applying a layer of copper configured to normalize a spread of heat across the printed circuit board. The configuration of the copper layer can be configured based on a tested or simulated heat map that accounts for proximate heat producing elements. The PCB can also advantageously act as an interconnection layer between other electrical components disposed within the electronic device.
