Publication number: 20220343825Abstract: A display device includes a controller, a panel driver, and a voltage generator. The controller generates a first control signal and generates image data and a second control signal in response to first and second image signals. The panel driver generates a driving signal in response to the image data and the first control signal to drive a display panel. The voltage generator generates a driving voltage to drive the display panel and changes a voltage level of the driving voltage in response to the second control signal. The first image signal corresponds to a second frame located before a third frame in which the driving voltage is changed. The second image signal corresponds to a first frame located before the second frame. The controller generates image data corresponding to the second frame in response to the first image signal and the second image signal.Type: ApplicationFiled: January 10, 2022Publication date: October 27, 2022Inventors: TAE-SEOK HA, KYOUNGSOO KIM, KYU-JIN PARK, SUNG-JAE PARK, SEUNG-WOON SHIN, HO LEE, WOON-ROK JANG

Publication number: 20060082521Abstract: In a display device, one field is divided into two groups of subfields. Light-emitting cells are selected by a selective write process in a first group of subfields and a gray scale is represented by a combination of weights of subfields. Light-emitting cells are selected by the selective write process in a first subfield of a second group of subfields, and non-light-emitting cells are selected from the light-emitting cells by a selective erase process in the remaining subfields of the second group of subfields. In the second group of subfields, a gray scale is represented by the sum of weights of subfields from when the light-emitting cell is selected in the first subfield to when the non-light-emitting cell is selected. In this manner, a gray scale of one field may be represented by a combination of the first and second groups of subfields.Type: ApplicationFiled: July 19, 2005Publication date: April 20, 2006Inventors: Seung-Rok Shin, Gab-Sick Kim, Hak-Cheol Yang
