Patent number: 7961264Abstract: A pixel electrode structure for a liquid crystal display with a high aperture ratio increases the aperture ratio and eliminates Mura phenomenon. Any two adjacent pixel electrodes are disconnected to each other. Each pixel electrode comprises a first-lengthwise periphery that overlaps a first-adjacent data line to form a first overlapping portion, and a second-lengthwise periphery that overlaps a second-adjacent data line to form a second overlapping portion. The first-lengthwise periphery and the second-lengthwise periphery have an identical triangle-wave profile and are symmetrical to each other. The triangle-wave profile is formed by connecting a plurality of right-angled and equilateral triangles.Type: GrantFiled: May 14, 2008Date of Patent: June 14, 2011Assignee: Hannstar Display Corp.Inventors: Hsiang-Lung Liu, Hsu-Ho Wu

Patent number: 7319504Abstract: A method of repairing an LCD panel having a mura defect is disclosed. The closed seal pattern of the LCD panel has a shape of frame with at least one jut portion directing to a peripheral side of the two substrates. Thus, when a mura defect occurs, a peripheral portion on one side of the two substrates is cut off, wherein the cutting passes across the jut portion of the closed seal pattern to form an opening with respect to the sealed region. An extra amount of liquid crystal can be pressed out through the opening. Then the opening is sealed using a sealant, such that the LCD panel having a mura defect is repaired.Type: GrantFiled: January 27, 2005Date of Patent: January 15, 2008Assignee: HannStar Display Corp.Inventors: Hsiang-Lung Liu, Kei-Hsiung Yang, Hsu-Ho Wu

Patent number: 6965424Abstract: A method of preventing seal damage in LCD panel manufacturing. A photo spacer pattern made of photoresist is used instead of extra seal pattern, such that tact time of sealing process is reduced, air blockage is enhanced, the number of TFT-array areas able to be formed on a glass substrate is increased, and chipping or unevenness of the panel resulting during panel cutting owing to extra seal patterns are all avoided.Type: GrantFiled: December 30, 2002Date of Patent: November 15, 2005Assignee: Hannstar Display Corp.Inventors: Hsiang Lung Liu, Hsu-Ho Wu

Patent number: 6862072Abstract: An ODF liquid crystal display panel is formed of a pair of mutually spaced-apart substrates. A liquid crystal layer is contained between the substrates. A first sealing member joins the substrates and defines an enclosed non-peripheral region in which the liquid crystal is contained. A second sealing member also joins the substrates. The second sealing member has a plurality of breaks, and is positioned inside the non-peripheral region defined by the first sealing member and divides the non-peripheral region into a display region and a buffer region in fluid communication with the display region. The gap between the substrates in the buffer region is larger than the gap between the substrates in the display region. The panel is formed by forming drops of liquid crystal in the display region and then joining the substrates using the sealing members. Excess liquid crystal flows through the breaks of the second sealing member into the buffer region.Type: GrantFiled: December 11, 2002Date of Patent: March 1, 2005Assignee: Hannstar Display Corp.Inventors: Hsiang Lung Liu, Hsu Ho Wu, Tai Kang Wu
