Liquid crystal display device
View Patent ↗A liquid crystal display device includes a liquid crystal display panel PNL including a pair of mutually opposed substrates, a display section which is composed of a plurality of matrix-arrayed display pixels, and a peripheral region surrounding the display section, a driving circuit, which drives the display pixels, a controller which controls the driving circuit, and a power supply circuit which supplies power to the driving circuit and the controller, wherein the controller and the power supply circuit are built in a 1-chip system IC and are disposed on the peripheral region.
1. A liquid crystal display device comprising:
a liquid crystal display panel including a pair of mutually opposed substrates, a display section which is composed of a plurality of matrix-arrayed display pixels, and a peripheral region surrounding the display section;
a driving circuit configured to drive the display pixels, and including a plurality of circuit sections which are disposed on the peripheral region;
a controller configured to control the driving circuit; and
a power supply circuit configured to supply power to the driving circuit and the controller,
wherein the controller and the power supply circuit are built in a 1-chip system IC without the driving circuit and are disposed on the peripheral region.
2. The liquid crystal display device according to claim 1 , further comprising a flexible board which is connected to the peripheral region, wherein a peripheral circuit, which is necessary for the system IC, is mounted on the flexible board.
3. The liquid crystal display device according to claim 1 , wherein the system IC is disposed on the peripheral region along an end side of the display section, and is positioned near a center of the end side.
4. The liquid crystal display device according to claim 1 , wherein the system IC is COG-mounted on one of the pair of substrates.
