Title
(EN) MITIGATING DISPLAY NOISE FOR TOUCH AND PEN SENSING
(FR) ATTÉNUATION DE BRUIT D'AFFICHAGE PERMETTANT LA DÉTECTION DE TOUCHER ET DE STYLO
Abstract
(EN)
A display device includes a display controller and a timing controller to drive frames at a frame rate onto a display. The display device may include sensor circuitry to detect a signal from a pen. The signal from the pen includes a sync signal indicative of a repetition rate of the signal. In one embodiment, the sync signal and the display timer are asynchronous. The sensor circuitry is configured to sense the signal from the pen during sensing windows, where timing of the sensing windows is based on the repetition rate. In one embodiment, the display controller is configured to pause driving a frame onto the display during the sensing windows.

L'invention concerne un dispositif d'affichage qui comprend un dispositif de commande d'affichage et un dispositif de commande de synchronisation afin de commander des trames à une fréquence de trame sur un écran. Le dispositif d'affichage peut comprendre un ensemble circuit de capteur destiné à détecter un signal provenant d'un stylo. Le signal provenant du stylo comprend un signal de synchronisation indiquant un taux de répétition du signal. Dans un mode de réalisation, le signal de synchronisation et le temporisateur d'affichage sont asynchrones. L'ensemble circuit de capteur est configuré pour détecter le signal provenant du stylo pendant des créneaux de détection, la synchronisation des créneaux de détection étant basée sur le taux de répétition. Dans un mode de réalisation, le dispositif de commande d'affichage est configuré pour mettre en pause la commande d'une trame sur l'écran pendant les créneaux de détection.
