Abstract
An active matrix display panel is operated by a color sequential system to form color images. A color generator is disposed between a light source and the display panel for sequentially providing red, green and blue light. A color sequential drive circuit controls the color generator and the pixels of the display panel. The color generator is preferably a multi-stage multiple wavelength blocking filter incorporating fast switching surface stabilized liquid crystal cells.
Claims20
A sequential color display for a communications device comprising:
- a wireless transceiver that receives image data;
- a light source comprising a plurality of light emitting devices (LEDS) that emit a plurality of different colors;
- a display panel optically coupled to the light source, the display panel including an array of pixel electrodes and an array of pixel circuits, each pixel circuit being formed with a single crystal silicon material;
- and
- a sequential color circuit connected to the display panel and the light source such that the light source generates a plurality of colors in temporal sequence, the sequential color circuit controlling a sequence of image frames formed on the display panel from the received image data at a rate of 60 frames per second or more.
A method of displaying images with a portable communications device comprising:
- providing a matrix display panel having an array of pixel electrodes and pixel circuits, the pixel circuits being formed with a single crystal silicon material;
- providing a light source including a plurality of light emitting devices (LEDs) emitting light of a plurality of different colors;
- receiving image data with a wireless transceiver;
- generating a plurality of image subframes from the received image data for each color image frame at a rate of 60 frames per second or more, each subframe having a different color;
- and
- displaying each subframe in temporal sequence on the matrix display panel using the light source to display a color image frame.
A portable communications device comprising:
- a wireless transceiver that receives image data;
- a light source including a plurality of light emitting devices (LEDs) emitting a plurality of different colors;
- a liquid crystal display panel optically coupled to the light source, the display panel including an active matrix circuit formed with a single crystal silicon material;
- and
- a sequential color circuit connected to the display panel and the light source such that the light source generates a plurality of colors in sequence to illuminate the display panel at a rate of 60 frames per second or more.
