Definitions

  • the memory may comprise a memory matrix of memory elements, wherein each pixel is assigned a memory element. Consequently, each pixel can be connected directly to a memory element.
  • the information structure of a complete image frame for all pixels of the display element can be executed in the memory. Only in a separate subsequent step, the information transfer to the pixels of the display element by overwriting the display values from the memory to the pixels can be performed.
  • the memory elements may be formed here as capacitors, transistors, or superconducting magnetic memory elements.
  • a drive unit may be provided which has drive circuits for each liquid crystal molecule, wherein, in particular, the drive unit simultaneously transfers all the display values of a completely stored image frame of one frame period to the pixels.
  • the drive circuits may be formed, for example, as transistors.
  • the drive unit according to the invention can generate the transfer pulse when the storage operation of a complete image frame in the memory is completely completed. After overwriting, the image structure of the subsequent image frame begins in the memory. The control electronics need not be changed except for the generation of the transfer pulse. The image frame currently represented by the image matrix remains unchanged within a frame period. There are no intermediate images.
  • the polarizers can be designed as a polarizing filter, wherein in particular their polarization directions are rotated by 90 ° to each other.
  • the polarized by the lower polarizer light in the liquid crystal layer can undergo a rotation of its plane of polarization of 90 ° and then pass unhindered through the upper polarizer. But if a field is created, this field forces the liquid crystal molecules to align along the field lines. The helix is destroyed.
  • an illumination plate can be arranged adjacent to one of the glass plates in order to either actively illuminate the display element or passively illuminate it with reflected light from a light source.
  • An active lighting panel may include, for example, light emitting diodes or organic light emitting diodes.
  • the illumination plate may be embodied as a mirror which reflects the light of a particularly punctual light source onto the liquid crystal display element.

Abstract

L'invention concerne un dispositif d'affichage (1) permettant la représentation d'image pour des téléviseurs ou des ordinateurs, comprenant deux plaques de support (20), au moins une plaque de support (20) présentant une couche d'électrode (30) qui commande l'élément d'affichage (10), l'élément d'affichage (10) présentant une matrice d'image (M) composée de points d'image (11) qui sont disposés en lignes horizontales (Z) et en colonnes verticales (S). Selon l'invention, la couche d'électrode (30) présente une première mémoire (50) dans laquelle des valeurs d'affichage (12) d'un cadre d'image (A, B) pour les points d'image (11) peuvent être mises en mémoire les unes après les autres, ligne (Z) par ligne (Z+1), et les points d'image (11) peuvent être simultanément excités quand toutes les valeurs d'affichage (12) d'une période d'image (R, T+1) pour la matrice d'image (M) complète sont présentes en totalité dans la première mémoire (50).
