Patent number: 9696845Abstract: Embodiments relate to a touch panel operable in a first haptic mode and a second haptic mode. The touch panel includes first electrodes and second electrodes intersecting the first electrodes. The touch panel further includes an elastic dielectric member disposed between the first electrodes and the second electrodes to separate the first electrodes and the second electrodes. The first electrodes are applied with a first voltage during the first haptic mode. The second electrodes are applied with a reference voltage in the first haptic mode. A subset of the second electrodes is applied with a second voltage to generate electrostatic force between the subset of the second electrodes and a user's finger in the second haptic mode. The elastic dielectric member vibrates in response to the first voltage applied to the first electrodes in the first haptic mode.Type: GrantFiled: May 15, 2015Date of Patent: July 4, 2017Assignee: LG Display Co., Ltd.Inventors: Eun Jung Kim, Ji Eun Son, Sung Yong Cho, Ki Seon Kim

Patent number: 9323084Abstract: A curved liquid crystal display device includes a liquid crystal display panel, a backlight unit, a bottom cover and a reinforcement frame. The liquid crystal display panel includes a thin film transistor substrate and a color filter substrate. The backlight unit applies light to the liquid crystal display panel. The bottom cover supports the backlight unit and has a flat shape. The reinforcement frame has a predetermined curvature and is attached to the bottom cover. The flat bottom cover is mounted on the reinforcement frame such that the flat bottom cover has the predetermined curvature of the reinforcement frame.Type: GrantFiled: September 5, 2013Date of Patent: April 26, 2016Assignee: LG DISPLAY CO., LTD.Inventors: Se-Min Lee, Hyun-Woo Jang, Ji-Eun Son, JooYoung Yeon, Jae-Yeon Song, Yong-Joong Yoon, Hyo-Sung Lee
