  • Patent number: 9430957
    Abstract: A virtual load board includes a connection port, a conversion circuit, and an indication unit, wherein the connection port comprises at least one terminal. The terminal receives an output voltage from the liquid crystal display control board. The conversion circuit converts the output voltage into an operating voltage for the indication unit and supplies the operating voltage to the indication unit. A test system and a test method for liquid crystal display control board are also provided. With the above-discussed arrangement, the virtual load board replaces a liquid crystal display panel to carry out a reliability test of the liquid crystal display control board, and has the advantages of small volume and low cost and can be accommodated, together with the liquid crystal display control board, in reliability test equipment in order to carry out a reliability test of the liquid crystal display control board in a specific environment.

  • Patent number: 8717050
    Abstract: A device for panel reliability testing and method thereof are proposed. The device includes a connection module, for connecting the panel and an aging module; a reliability chamber control module for sending a voltage regulation command to a bias module and/or a switch control command to the aging module; the bias module, for regulating voltage and transmitting information about voltage regulation to the aging module; and the aging module, for performing an aging operation on the panel depending on the switch control command sent from the reliability chamber control module and the information about voltage regulation transmitted from the bias module. Compared with the prior art, LCD panels undergo the aging testing before being packaged, thereby shortening a time period of manufacturing LCD panels and enhancing production efficiency.

  • Publication number: 20130140291
    Abstract: A glass substrate slicing apparatus is disclosed, which comprises a laser emitting device and a slicing device. The laser emitting device is adapted to emit a laser beam onto a surface of a glass substrate to be sliced so as to form micro-grooves on the surface of the glass substrate; and the slicing device is adapted to slice the glass substrate at locations of the micro-grooves, and comprises a wheel cutter fixing device and a diamond wheel cutter fixed on the wheel cutter fixing device. A laser beam is emitted by the laser emitting device to form micro-grooves on a surface of the glass substrate so that a diamond wheel cutter can be inserted into the micro-grooves to slice the glass substrate at locations of the micro-grooves. As a result, the frictional force between the diamond wheel cutter and the glass substrate can be enhanced to prevent slipping of the diamond wheel cutter during the slicing process, thus improving the slicing accuracy.

  • Publication number: 20130135549
    Abstract: The present invention discloses a thin film transistor (TFT) array substrate, a liquid crystal display (LCD) and a method for manufacturing the same. The method comprises: forming coating layers on a display region and a non-display region of a first substrate; forming a stacked layer on the non-display region; forming at least one channel on the stacked layer by exposure and developing; filling the channel with a sealant; and bonding the first substrate to a second substrate by using the sealant. The present invention can precisely control the shape of the sealant for preventing the leakage of the sealant and an uneven cell thickness.
