  • Patent number: 9348180
    Abstract: The present invention relates to a method for fabricating an LCD panel. The method includes the steps of: (A) forming a black matrix layer on a color filter substrate; and (B) attaching the color filter substrate to a corresponding array substrate for forming a liquid crystal cell, and applying a voltage on the black matrix layer for liquid crystal molecules in the liquid crystal cell being arranged at a pretilt angle. The fabricating method of the present invention can realize photo alignments on multiple partitions without demand in shapes of the pixel electrodes.

  • Patent number: 9170460
    Abstract: The present invention provides to an in-plane-switching (IPS) mode liquid crystal panel, which comprises: a first substrate, a second substrate, a coplanar transparent electrode layer and a liquid crystal layer. The first and second substrates have a first alignment film and a second alignment film, respectively. The coplanar transparent electrode layer is disposed onto the second alignment film. The liquid crystal layer is disposed in a space between the first alignment film of the first substrate and the coplanar transparent electrode layer of the second substrate. The liquid crystal layer comprises dual-frequency liquid crystal molecules and dual-frequency reactive mesogens/monomers. The liquid crystal panel of the present invention can overcome the problems of pollution and static electricity generated from the rubbing alignment in the in-plane-switching (IPS) mode, so as to simplify the manufacturing process and provide the advantages of high contrast, high response speed and wide viewing angle.

  • Patent number: 9025092
    Abstract: A display device including a liquid crystal lens and a display panel is provided. The liquid crystal lens is disposed above the display panel and includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first and the second substrates, driving electrodes located between the first substrate and the liquid crystal layer and arranged in a pitch, and an opposite electrode layer located between the second substrate and the liquid crystal layer. The display panel has display units arrange in the pitch. In a 3D display mode, two adjacent driving electrodes in the liquid crystal lens are respectively driven at a first time period and a second time period. The liquid crystal lens and the display panel are switched synchronically so that each display unit respectively displays images with different parallax at the first and the second time periods.

  • Patent number: 8982298
    Abstract: The backplane for a liquid crystal display (LCD) device includes side walls, and the backplane at least includes two backplane units. A horizontal moving guide device is arranged between the adjacent backplane units, and an elastic device which enables the two backplane units to relatively elastically expand and contract horizontally is further arranged between the adjacent backplane units. The backplane of the LCD device of the present disclosure is designed to be able to elastically expand and contract in a direction perpendicular to a light emitting diode (LED) lightbar. When a light guide panel (LGP) in the backplane expands after absorbing heat, the backplane is extended by a pushing force, and heat expansion quantity of the LGP is directly absorbed. When the LGP is contracted because of temperature drop, the backplane is shortened under action of the elastic device, and a light coupling distance between the LGP and the LED lightbar is always kept constant.

  • Patent number: 8804087
    Abstract: An object of the present invention is to reliably ground an external conductive film formed on an opposed substrate to secure a stable shield effect in an IPS-type liquid crystal display device. An external conductive film formed on an opposed substrate is connected to an earth pad formed on a TFT substrate through a conductive thermocompression bonding tape. The conductive thermocompression bonding tape is connected by a thermocompression bonding head to form a conductive area. The width of the conductive area on the opposed substrate is made larger than the width of the conductive area on the TFT substrate to prevent the conductive thermocompression bonding tape from peeling off from the opposed substrate. Accordingly, the external conductive film of the opposed substrate is reliably grounded.
