Title (EN) ACTIVE MATRIX DISPLAY DEVICES, AND THEIR MANUFACTURE
(FR) DISPOSITIFS D'AFFICHAGE A MATRICE ACTIVE ET LEUR PRODUCTION
Abstract: front page image
(EN)Physical barriers (210) are present between neighbouring pixels (200) on a circuit substrate (100) of an active-matrix display device, such as an electroluminescent display formed with LEDs (25) of organic semiconductor materials. The invention forms at least parts of the barriers (210) with metal or other electrically-conductive material (240) that is insulated (40) from the LEDs but connected to the circuitry (4, 5, 6, 9, 140, 150, 160, T1, T2, Tm, Tg, Ch etc.) within the substrate (100). This conductive barrier material (240) may back up or replace, for example, matrix addressing lines (150) and/or form an additional component either within the pixel array or outside. The additional component comprising the conductive barrier material (240) is advantageously a capacitor (Ch), or an inductor (L) or transformer (W), or even an aerial.
(FR)Des barrières physiques (210) sont présentes entre des pixels voisins (200) sur un substrat (100) de circuit d'un dispositif d'affichage à matrice active, tel qu'un affichage électroluminescent constitué de DEL (25) en matériaux semi-conducteurs organiques. L'invention forme au moins deux parties des barrières (210) d'un métal ou d'un autre matériau électro-conducteur (240) qui est isolé (40) des DEL mais est connecté au circuit (4, 5, 6, 9, 140, 150, 160, T1, T2, Tm, Tg, Ch etc.) à l'intérieur du substrat (100). Ce matériau barrière conducteur (240) peut assister ou remplacer, par exemple, des lignes (150) d'adressage de matrice et/ou former un constituant supplémentaire soit à l'intérieur du réseau de pixels soit à l'extérieur. Le constituant supplémentaire comprenant le matériau barrière conducteur (240) est avantageusement un condensateur (Ch), un inducteur (L) ou un transformateur (W), ou même une antenne.
