Definitions

  • the circuit board is located between the first and second liquid crystal display sections, and the first and second liquid crystal display sections are both the beautiful color liquid crystal display sections, And each includes a liquid crystal display screen, a beautiful picture and a light guide plate which are stacked one on top of the other in turn.
  • the dual color screen mobile phone of the present invention can make the main screen and the secondary screen larger at the same time at a low cost, thereby meeting people's needs for the aesthetic sense of the mobile phone.
  • a protective screen is provided on the outside of the liquid crystal display screen, and the protective screen is a liquid crystal protective screen with holographic images.
  • FIG. 4C is an exploded view of a beautiful picture with a four-layer structure in the present invention.
  • the diffusion sheets 14 and 14 can eliminate the grid displayed on the liquid crystal display panels 11 and 1 ⁇ caused by the grating on the light guide plate 13 and make the emitted light more uniform.
  • the shadow of the reflection point is not visible on the front side, thereby further enhancing the display effect.
  • the light emitting diode 21 emits bright light under the action of the driving circuit on the LCD circuit board 1, and generates a backlight with uniform brightness through the light guide plate 13 described above, and is further enhanced by the reflective sheet 14 disposed inside the light guide plate 13.
  • the intensity of the backlight has further enhanced the color display effect.

Abstract

L'invention concerne un combiné téléphonique comportant un écran d'affichage deux couleurs et qui comprend : un corps principal, une partie repliable reliée au corps principal, une carte à circuit imprimé montée dans le corps principal et un écran à cristaux liquides connecté électriquement à ladite carte. L'écran à cristaux liquides monté sur le corps principal comprend un premier port d'écran à cristaux liquides destiné à l'écran principal, et un second port d'écran à cristaux liquides destiné à un écran secondaire. Le premier et/ou le second port d'écran à cristaux liquides est/sont formé(s) par l'empilement d'éléments constitutifs les uns sur les autres, dans l'ordre suivant : écran à cristaux liquides, image couleur, plaque guide de lumière. Ce combiné à écran d'affichage deux couleurs permet non seulement de très bien visualiser des images couleur, mais présente aussi de nombreuses qualités telles que construction simple, traitement pratique, faible coût, faible consommation d'énergie et effet d'affichage couleur.
