Patent number: 6927755Abstract: A device to minimize the flickering phenomenon of thin-film-transistor liquid-crystal-display (TFT-LCD), and prevent the discharge insufficiency problem when the TFT operates under low temperature. The device primarily uses temperature compensation components or circuits to achieve a VGH curve corresponding to the temperature characteristics of the TFT. The gate pulse is slashed more substantially at high temperature and less at low temperature so that the recharging problem at low temperature is solved.Type: GrantFiled: July 17, 2001Date of Patent: August 9, 2005Assignee: Unipac Optoelectronics CorporationInventor: Yung Yi Chang

Patent number: 6682039Abstract: A locator for a material sheet comprises at least two oppositely disposed stoppers, and a slot sheet. Each of the stoppers provides a flat bearing surface and a slant surface extending outward and upward from the bearing surface with a junction between them. The slot sheet is disposed under the stoppers and joining to a bottom of the respective stopper. The distance between the junctions on the two stoppers is corresponding to the length of the slot sheet.Type: GrantFiled: May 31, 2001Date of Patent: January 27, 2004Assignee: Unipac Optoelectronics CorporationInventors: Tsung-Lin Lu, Ta-Shuang Kuan

Publication number: 20020139306Abstract: A locator for a material sheet comprises a frame with a homogeneous cross section, and a susceptor. The frame at the left, the right, the front, and the rear sides thereof surrounds with an inner wall. The distance between the left and the right sides of the inner wall and the distance between the front and the rear sides thereof are corresponding to the size of the upward projection of the susceptor. The upper end of the inner wall extends outward a horizontal support surface. The distance between the left and the right sides of the support surface and the distance between the front and the rear sides of the support surface are corresponding to the size of the sheet. An upward slant surface extends outward from the support surface. The sheet can slide downward along the slant surface to cover the susceptor while the sheet is laid down from the top of the locator.Type: ApplicationFiled: May 31, 2001Publication date: October 3, 2002Applicant: Unipac Optoelectronics CorporationInventors: Tsung-Lin Lu, Ta-Shuang Kuan, Kuen-Jian Chen

Publication number: 20020105261Abstract: an FED cathode plate with internal via includes an internal via; a second dielectric layer; a second gate line; a metal layer 12 covering the gate line and the internal via; and a contact. The internal via is located on a typical tape line. The second dielectric layer is located on the tape line and abutted against the internal via, thereby connecting to an anode by an adhesive. The second gate line is located on the second dielectric layer and abutted against the internal via. The metal layer is covered over the first gate line, the internal via, and the second gate line; and the contact is located on the tape line and connected adjacent to the second dielectric layer, thereby electrically connecting a lead to outside.Type: ApplicationFiled: November 7, 2001Publication date: August 8, 2002Applicant: UNIPAC OPTOELECTRONICS CORPORATIONInventor: Chih-Chin Chang

Publication number: 20020076537Abstract: A first substrate, a second substrate, an intermediate and a plurality of particles form a laminated structure. The first substrate has a first conjunction portion and a second conjunction portion, and the second substrate has a third conjunction portion and a fourth conjunction portion which are characterized by a first hardness. The intermediate is disposed between the first substrate and the second substrate. The particles provided with a second hardness greater than the first hardness are coated on the third conjunction portion to contact the first conjunction portion and coated on the fourth conjunction portion to contact the second conjunction portion. A height difference with reference to the base surface of the second substrate exists between the end surface of the third conjunction portion and the end surface of the fourth conjunction portion.Type: ApplicationFiled: August 1, 2001Publication date: June 20, 2002Applicant: Unipac Optoelectronics CorporationInventors: Ling-Yi Chuang, Li-Chang Lu
