Publication number: 20230206815Abstract: A display data adjustment method is provided, including the following. First display data is received, and first grayscale values of first sub-pixels of different colors in the first display data are converted from a first color gamut space into color values in a second color gamut space. First weight values are generated according to the color values. Lookup tables are compared according to the first grayscale values of the first sub-pixels to obtain groups of first high grayscale values and first low grayscale values corresponding to the first sub-pixels. Second high grayscale values and second low grayscale values are obtained by calculation according to the groups of the first high grayscale values and the first low grayscale values and the first weight values. The second high grayscale values or the second low grayscale values are selected as second grayscale values of second sub-pixels in second display data.Type: ApplicationFiled: November 23, 2022Publication date: June 29, 2023Applicant: Innolux CorporationInventors: Chien-Hung Chan, Meng-Chang Tsai, Huang-Chi Chao, Chan-Feng Chiu, Shiau-Ting Haung

Publication number: 20230186817Abstract: A light source driving circuit and a method for driving a light source are provided. The light source driving circuit includes a filter. The filter is configured to receive a pixel signal. The filter selects one filter parameter from multiple filter parameters according to a gray level value of the pixel signal. The filter performs a filter operation on the pixel signal according to the selected filter parameter, so as to output a driving signal to drive a light source module. The filter parameters include a first filter parameter, a second filter parameter, and a third filter parameter. The second filter parameter is obtained by performing an interpolation operation on the first filter parameter and the second filter parameter via the filter.Type: ApplicationFiled: November 9, 2022Publication date: June 15, 2023Applicant: Innolux CorporationInventors: Ming-Feng Hsieh, Cheng-Tso Hsiao, Chien-Hung Chan, Huang-Chi Chao
