Abstract
Disclosed is a backlighting device for a dual LCD (Liquid Crystal Display). The backlighting device includes a circuit board with a through hole; a backlighting illumination device situated within the hole for radiating light in a first direction substantially perpendicular to a first face of the circuit board and in a second direction substantially perpendicular to a second face of the circuit board; a main LCD being situated on one face of the backlighting illumination device in the first direction, for displaying first information in the first direction; and a slave LCD being situated on another face of the backlighting illumination device through the through hole in the second direction, for displaying second information in the second direction.
Claims20
A backlighting device for a dual LCD (Liquid Crystal Display), comprising:
- a circuit board having a hole located therein;
- a backlighting illumination device situated within the hole for radiating light in a first direction substantially perpendicular to a first face of the circuit board and in a second direction substantially perpendicular to a second face of the circuit board;
- a main LCD being situated on a first face of the backlighting illumination device in the first direction, for displaying first information in the first direction;
- and
- a slave LCD being situated on second face of the backlighting illumination device through the through hole in the second direction, for displaying second information in the second direction.
A folder-type mobile phone with a backlighting device for a dual LCD, comprising:
- a body;
- the backlighting device including;
- a circuit board having a hole located therein;
- a backlighting illumination device situated within the hole for radiating light in a first direction substantially perpendicular to a first face of the circuit board and in a second direction substantially perpendicular to a second face of the circuit board;
- a main LCD situated on first face of the backlighting illumination device in the first direction, for displaying first information in the first direction;
- a slave LCD situated on a second face of the backlighting illumination device and located within the hole in the second direction, for displaying second information in the second direction;
- and
- a folder rotatably foldable to the main body by a hinge device.
A backlighting device for a dual LCD (Liquid Crystal Display), comprising:
- a main LCD;
- a slave LCD;
- a light source located between said main LCD and said slave LCD;
- and
- a semi-transparent polarizer, located between said main LCD and said light source, for transmitting through said main LCD a percentage of light generated by said light source, and reflecting through said slave LCD a percentage of said light generated by said light source.
A backlighting device for a dual LCD (Liquid Crystal Display), comprising:
- a main LCD, comprising:
- a main liquid crystal having an upper surface and a lower surface;
- a main upper glass located on said upper surface of said main liquid crystal;
- a main lower glass located on said lower surface of said main liquid crystal;
- a main upper polarizer located on said main upper glass;
- and
- a semi-transparent lower polarizer located on said main lower glass;
- a slave LCD, comprising:
- a slave liquid crystal having an upper surface and a lower surface;
- a slave upper glass located on said upper surface of said slave liquid crystal;
- a slave lower glass located on said lower surface of said slave liquid crystal;
- a slave upper polarizer located on said slave upper glass;
- and
- a slave lower polarizer located on said slave lower glass;
- and
- a light source located between said semi-transparent lower polarizer and slave upper polarizer,
- wherein said semi-transparent lower polarizer transmits through said main LCD a percentage of light generated by said light source, and reflects through said slave LCD a percentage of said light generated by said light source.
