Abstract
A display device includes more than one IC chip formed on a substrate. Analog signals are applied to the ICs with a point-to-point structure. Digital signals are applied to the ICs with a cascade structure. Wirings applying digital signals are widened in the areas having room available so that electrical resistance can be reduced. Wirings in areas not having enough room to widen are applied with multi path technology to reduce electrical resistance. Multi contact technology may be applied to contact the ICs to a glass substrate.
Claims13
A display device comprising:
- a first source IC which is electrically coupled to a control board through a first digital power circuit and a first analog power circuit;
- a second source IC which is electrically coupled to the first source IC through a second digital power circuit;
- and
- a second analog power circuit which couples the second source IC to the control board,
- wherein the second analog power circuit is not coupled directly to the first source power source IC.
