Abstract
The invention relates to a microdisplay system that utilizes a small high resolution active matrix liquid crystal display with an illumination system and a magnifying optical system to provide a hand held communication display device. The system can employ an LED illumination system and cellular communication or processor circuits within a compact housing to provide communication devices such as pagers, telephones, televisions, and hand held computer or card reader devices with a compact high resolution data and/or video display.
Claims20
A wireless telephone having a display panel comprising:
- a handset housing having a speaker and a microphone within the housing;
- a transceiver system within the handset housing that receives audio and image data;
- a display module housing that is connected to the handset housing and that houses a liquid crystal active matrix display, a backlight and a lens that magnifies a displayed image on the matrix display, the matrix display having at least 75,000 pixel electrodes defining an active area of less than 160 mm.sup.2 and the backlight including a light emitting diode (LED);
- and
- a display control circuit connected to the transceiver system and the matrix display.
A method of displaying an image on a wireless telephone having a display panel comprising:
- providing a handset housing having a speaker and a microphone within the housing;
- providing a transceiver system within the housing that receives audio and image data;
- providing a display module having a liquid crystal active matrix display, a backlight and a lens that magnifies a displayed image on the matrix display, the matrix display having a plurality of pixel transistor circuits formed with a single crystal silicon material and at least 75,000 pixel electrodes defining an active area of the display of less than 160 mm.sup.2 and the backlight including a plurality of light emitting diodes (LEDs);
- and
- operating a display control circuit connected to the transceiver and the matrix display to display an image on the display.
A wireless telephone having a display panel comprising:
- a handset housing having a speaker and a microphone within the housing;
- a transceiver system within the handset housing that receives audio and image data;
- a display module housing having a liquid crystal active matrix display, a backlight, a diffuser between the backlight and the display, and a lens that magnifies a displayed image on the matrix display, the display having a plurality of pixel transistor circuits formed with a single crystal silicon material and at least 75,000 pixel electrodes defining an active area of the display of less than 160 mm.sup.2, the backlight including a red light emitting diode (LED), a green LED and a blue LED.
