Abstract:
In described embodiments, a thin film transistor (TFT) liquid crystal display (LCD) structure incorporates a white light emitting diode (LED) structure for backlighting. White LEDs are formed behind each TFT cell, allowing for display “black” as a function of a nematic layer, on the TFT substrate, while increasing intensity of the LED LCD backlight structure. A lens structure might be formed between the LEDs and the TFT substrate to reduce a number of LED sources for a given backlight intensity.
