Abstract
Liquid crystal displays (LCDs) have become main stream in the flat panel display industry and the use of light emitting diode (LED) array as a backlight unit (BLU) for LCDs is emerging. However, the currently used LED for the backlight unit is a point light source and due to the optomechanical limitations, the LED backlight is not an ideal rectangular backlight. Fortunately, a BLU based on field emission satisfies such demand. The point spread function (PSF) for both LED and field efect back light unit (FE BLE) are shown. The simulation results indicate that the good property of field emission (FE) as a flat light source shows its prospective feature in the application as the BLU for LCDs.
