Title
(EN) LIQUID CRYSTAL DISPLAY WITH HIGH CAPACITANCE PIXEL
(FR) AFFICHAGE A CRISTAUX LIQUIDES A PIXEL HAUTE CAPACITE
Abstract
(EN)
A liquid crystal display includes a base plate (26) having a plurality of pixels on a surface thereof with the pixels arranged in an array of spaced rows and columns. Each of the pixels includes a substantially rectangular region (30) of polycrystalline silicon. A separate select line (32) of polycrystalline silicon extends over and across the polycrystalline silicon regions of each row of pixels adjacent one side of the polycrystalline silicon region. The select lines have two extensions (34) extending over and along two opposite sides of each polycrystalline silicon region (30). A layer of a dielectric material (36) extends between the polycrystalline silicon regions and the select lines (32) and the extensions (34) of the select lines. Each of the select lines (32) and its extensions (34) forms a capacitor with the respective polycrystalline silicon region of each pixel. Data lines (38) extend along the rows of the pixels and are electrically connected (44) to each polycrystalline silicon region (30) in its respective column of pixels.

Un affichage à cristaux liquides comporte une plaque de base (26) présentant, sur un surface, une pluralité de pixels disposés en un réseau de rangées et de colonnes espacées. Chacun des pixels comprend une région sensiblement rectangulaire (30) en silicium polycristallin. Une ligne de sélection séparée (32) de silicium polycristallin s'étend sur et à travers les régions de silicium polycristallin de chaque rangée de pixels adjacente à un côté de la région de silicium polycristallin. Les lignes de sélection présentent deux prolongements (34) s'étendant sur et le long de deux côtés opposés de chaque région de silicium polycristallin (30). Un couche d'un matériau diélectrique (36) s'étend entre les régions de silicium polycristallin et les lignes de sélection (32) ainsi que leurs prolongements (34). Chacune des lignes de sélection (32) et de ses extensions (34) forme un condensateur avec la région de silicium polycristallin respective de chaque pixel. Des lignes de données (38) s'étendent le long des rangées des pixels et sont reliées électriquement (44) à chaque région de silicium polycristallin (30) dans sa colonne respective de pixels.
