Multi-angle display device containing lens
View Patent ↗A multi-angle display device containing a lens. The multi-angle display device containing a lens includes a display panel having a plurality of unit pixels disposed therein; a data driving circuit including a plurality of source drive ICs to drive data lines of the display panel; a gate driving circuit including one or more gate driving ICs to sequentially supply scan pulses to gate lines of the display panel; a timing controller receiving a plurality of timing signals from an external system and generating control signals for controlling operation timings of the data driving circuit and the gate driving circuit; and a lens arranged to be spaced apart from the unit pixel by a predetermined distance, in which the unit pixel includes a plurality of light sources.
1. A multi-angle display device containing a lens, comprising:
a display panel having a plurality of unit pixels disposed therein;
a data driving circuit including a plurality of source drive integrated circuits (ICs) to drive data lines of the display panel;
a gate driving circuit including one or more gate driving ICs to sequentially supply scan pulses to gate lines of the display panel;
a timing controller receiving a plurality of timing signals from an external system and generating control signals for controlling operation timings of the data driving circuit and the gate driving circuit; and
a lens arranged to be spaced apart from the unit pixel by a predetermined distance, wherein the unit pixel includes a plurality of light sources, wherein a plurality of light sources constituting the unit pixel surround the lens at a predetermined angle, and the lens is a spherical lens.
2. The multi-angle display device of claim 1 , wherein each of the plurality of light sources constituting the unit pixel has a blocking wall disposed on the outside.
3. The multi-angle display device of claim 1 , wherein each of the plurality of light sources constituting the unit pixel is located at an optimum focal length from a center of the lens, and the optimum focal length is calculated by the following equation:
