Patents by Inventor Jen-Lang Tung

Jen-Lang Tung has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060164588
    Abstract: A liquid crystal display panel is provided. The liquid crystal display panel includes a first substrate, a second substrate disposed parallel to the first substrate, a liquid crystal layer interposed therebetween, and a plurality of hybrid spacers disposed between the first substrate and second substrate, wherein the hybrid spacers comprise a soft material and a rigid material.

  • Publication number: 20060139560
    Abstract: A method for manufacturing a liquid crystal panel is disclosed. A mixture of liquid crystal and a solidifying material is dropped on a first substrate. A second substrate is provided such that the mixture is disposed between the first substrate and the second substrate. The solidifying material is solidified to connect the first and second substrates.

  • Patent number: 7064800
    Abstract: A gamma correction LCD panel and a fabrication of the same are provided. In the method, a lower substrate is firstly painted with a photo-alignment material. An exposing step is then introduced to have the photo-alignment material absorbed different amounts of light exposure so as to create various photo-aligning effects with respect to RGB pixel devices. The lower substrate is then assembled with an upper substrate and has an LC layer inter-filled. Upon such an arrangement, the LC layers with respect to RGB illumination can be thus provided with various transparencies for further adjust the RGB gamma curves individually.

  • Publication number: 20060114404
    Abstract: A spacer and a liquid crystal display panel using the same are provided. The spacer is located between a first substrate and a second substrate. The spacer includes a bottom portion and a neck portion. The bottom portion is disposed on the first substrate. The neck portion is disposed on the bottom portion. The contact area between the neck portion and the bottom portion is smaller than that between the bottom portion and the first substrate.

  • Publication number: 20050110809
    Abstract: A gamma correction apparatus comprising a digital to analog converter (DAC), a plurality of compensating circuits, and at least one adjusting circuit is provided. The DAC is used to receive RGB digital signals to further generate analog signals. The analog signals are then transferred to the relative pixel devices through the signal lines on the LCD panel. The compensating circuits inserted between the DAC and the signal lines are used to adjust the analog signals to correct the displaying brightness of the pixel devices. The adjusting circuit connecting to the compensating circuits is used to control the operation of the compensation circuits. In addition, a method for adjusting gamma curves by providing three common voltage levels related to RGB colors individually is also provided to achieve better white balance.
