Publication number: 20240122011Abstract: A display device includes a first conductive pattern layer connected to a signal line, a second conductive pattern layer connected to the first conductive pattern layer, and an insulation pattern layer disposed between the signal line and the second conductive pattern layer and overlapping the second conductive pattern layer. The second conductive pattern layer exposes a portion of an upper surface and a side surface of the insulation pattern layer. The second conductive pattern layer includes first and second edge portions disposed on the upper surface of the insulation pattern layer and facing each other in a second direction intersecting a first direction. A distance between the first and second edge portions decreases as moving along the first direction in a first region of the upper surface of the insulation pattern layer, and increases as moving along the first direction in a second region of the upper surface.Type: ApplicationFiled: September 20, 2023Publication date: April 11, 2024Applicant: Samsung Display Co., Ltd.Inventors: HEEJU WOO, CHOLONG WON, KIKYUNG YOUK, SEUNG-SOO RYU

Publication number: 20110085092Abstract: A mobile terminal includes an optical modulation projector. The mobile terminal also includes a control system, a projection control unit, and an optical modulation system. The control system outputs a projection control signal and image data. The projection control unit receives the image data from the control system, and generates and outputs a drive control signal depending on the image data received. The optical modulation system generates and modulates light and generates an image in response to the drive control signal and then scans the image for projecting onto a screen.Type: ApplicationFiled: October 15, 2010Publication date: April 14, 2011Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Sang Kyeong Yun, In Jae Yeo, Haeng Seok Yang, Chun Gi Kim, Kyu Bum Han, Seung Won Ryu

Publication number: 20080055340Abstract: An aspect of the present invention features a display apparatus. The apparatus can comprise: an optical modulator that modulates brightness of the incident light from a light source corresponding to a driving voltage and outputs the modulated light; a driver integrated circuit that supplies a driving voltage according to an image control signal to the optical modulator; a scanner that projects the modulated light to a position on a screen; and an image control circuit that generates and outputs the image control signal from an input image signal for reducing influence of drive characteristics of the optical modulator. An image control circuit and a display apparatus according to the present invention can reflect drive characteristics of a micromirror of an optical modulator to output grayscale data corrected by using grayscale data outputted already and grayscale data desired to be outputted at now, thereby displaying purposed grayscale.Type: ApplicationFiled: August 31, 2007Publication date: March 6, 2008Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: In-Jae Yeo, Seung-Won Ryu
