Abstract: A method of manufacturing a light guide for a backlight module in a liquid crystal display module is provided. The method includes the following steps: providing a foil; and pressing the foil at a first temperature above a glass transition temperature of a material of the foil to form a thickness profile of the light guide.

Abstract: The invention relates to liquid crystal display comprising image forming layers, at least one indirect light source and a light guide. The light guide comprises a first side facing the image forming layers, a second side opposite of the first side, and an in-coupling side facing the at least one indirect light source. The in-coupling side is a beveled in-coupling side.

Abstract: The invention relates to a display device comprising a plurality of light emitting elements (1), wherein at least one of the elements has an associated capacitor (C1). The display device comprises pre-charging means (7;8) for generating a pre-charge signal for charging the associated capacitor (C1) at least partly. The pre-charging means (7;8) are adapted for generating a pre-charge signal comprising at least a first pre-charge signal in a first pre-charge stage and a second pre-charge signal in a second pre-charge stage. The pre-charge signal preferably comprises a current pre-charge signal followed by a voltage pre-charge signal. The combined pre-charge signal has the advantage of fast, but accurate pre-charging.
