Abstract:
(EN) This display device is provided with: a display panel including a plurality of pixel circuits, each having an electro-optic device; a touch panel provided on the surface of the display panel; a display panel drive circuit; and a touch panel drive circuit. The display panel drive circuit writes a data voltage to the display panel during certain periods, and the touch panel drive circuit reads a signal from the touch panel during other periods. During display-off periods included in frame periods, the touch panel drive circuit reads a signal from the touch panel, and the display panel drive circuit writes, to all pixel circuits, a display-off voltage for stopping the electro-optic devices from emitting light. A compensation unit performs compensation processing on an input video signal so as to compensate for the differences in luminance between the electro-optic devices due to the differences between the lengths of the periods of light emission of the electro-optic devices.
(FR) Selon la présente invention, ce dispositif d'affichage comprend : un panneau d'affichage comprenant une pluralité de circuits de pixels, chacun ayant un dispositif électro-optique ; un panneau tactile disposé sur la surface du panneau d'affichage ; un circuit d'excitation de panneau d'affichage ; et un circuit d'excitation de panneau tactile. Le circuit d'excitation de panneau d'affichage écrit une tension de données sur le panneau d'affichage pendant certaines périodes, et le circuit d'excitation de panneau tactile lit un signal provenant du panneau tactile pendant d'autres périodes. Pendant des périodes d'affichage comprises dans des périodes de trame, le circuit d'excitation de panneau tactile lit un signal à partir du panneau tactile, et le circuit d'excitation de panneau d'affichage écrit, sur tous les circuits de pixel, une tension d'affichage pour empêcher les dispositifs électro-optiques d'émettre de la lumière. Une unité de compensation effectue un traitement de compensation sur un signal vidéo d'entrée de façon à compenser les différences de luminance entre les dispositifs électro-optiques en raison des différences entre les longueurs des périodes d'émission de lumière des dispositifs électro-optiques.
(JA) 表示装置は、それぞれが電気光学素子を有する複数の画素回路を含む表示パネルと、表示パネルの表面に設けられたタッチパネルと、表示パネル駆動回路と、タッチパネル駆動回路とを備える。表示パネル駆動回路とタッチパネル駆動回路は、表示パネルへのデータ電圧の書き込みとタッチパネルからの信号の読み出しとを互い異なる期間で行う。フレーム期間内に設けられた表示オフ期間において、タッチパネル駆動回路はタッチパネルからの信号の読み出しを行い、表示パネル駆動回路はすべての画素回路に対して電気光学素子の発光を停止させる表示オフ電圧を書き込む。補正部は、入力映像信号に対して、電気光学素子の発光期間の長さの差に起因する輝度の差を補償するための補正処理を行う。
