  • Patent number: 6839117
    Abstract: The present invention provides a display panel with compensating electrodes, having pixels comprising a plurality of the first electrodes and the second electrodes, and an insulating layer between the first electrodes and the second electrodes. Each pixel can be divided into the first sub-pixel including the first domain and the second domain, the second sub-pixel near the first sub-pixel and including the third domain and the fourth domain, and the third sub-pixel near the second sub-pixel and including the fifth domain and the sixth domain. The first electrodes are parallel to the second electrodes in each domain. The first electrodes are under the second electrodes in the first domain, the fourth domain and the fifth domain. The first electrodes are above the second electrodes in the second domain, the third domain and the sixth domain. Due to the different position in the neighboring domains, the asymmetrical structure is capable of compensating internal DC.

  • Patent number: 6798483
    Abstract: A floating electrode switching liquid crystal display (FES-LCD). A plurality of liquid crystal molecules held between the first substrate and the second substrate, and the liquid crystal molecules are aligned to a first direction. A plurality of transverse-extending gate lines and lengthwise-extending signal lines formed on the first substrate to define a plurality of pixel areas arranging in a matrix form. A plurality of pixel electrodes and floating electrodes formed on the first substrate, the pixel electrodes and the floating electrodes are positioned within the pixel areas, and being arranged to a second direction. A common electrode layer formed on the second substrate. The pixel electrodes and the floating electrodes are separated in the same plane, and the first direction and the second direction are intersected with an angle &thgr;.

  • Patent number: 6285428
    Abstract: A liquid crystal display device with an IPS mode having wide view angle characteristic and capable of improving response time and transmittance, is disclosed. A liquid crystal display device with an in-plane switching mode includes a first substrate having first and second electrodes formed thereon. A second substrate is disposed opposite to the first substrate with a selected distance. On a surface of the second substrate are also formed third and fourth electrodes. When a voltage is applied to the respective electrodes, a first electric field which is parallel to the planes of the substrates is generated between the first electrode and the second electrode, and a second electric field which is parallel to the planes of the substrates and is orthogonal to the first electric field is generated between the third electrode and the fourth electrode. A polarizer is arranged on the outside of the first substrate and a analyzer is arranged on the outside of the second substrate.

  • Patent number: 6215542
    Abstract: In a liquid crystal display having a pixel electrode and a counter electrode respectively formed on a lower substrate and a upper substrate, the electric field in ellipse form, is symmetrical between the pixel electrode and the counter electrode by forming an opening part in the pixel electrode or the counter electrode. Accordingly, the viewing angle feature, when voltage is applied to the liquid crystal display is enhanced.
