Liquid crystal display device having video signal driving circuit mounted on one side and housing

TL;DR: In this article, a liquid crystal display device and a data processing device can have their frame portions reduced in area to reduce the size and weight by extracting the terminals of video signals to only one side of a display panel and arranging a video signal line driving circuit substrate to be connected with the terminals.
Patent

Liquid crystal display device with its upper and lower cases clamped by crimping portions thereof

TL;DR: In this paper, a liquid crystal display device is described, where the upper and lower cases are clamped by crimping plural nails formed in the sidewall of the upper case at an outer surface of the lower case after stacking the liquid-crystal display element, the flexible circuit board and the illuminating light source.
Patent

TFT active matrix liquid crystal display devices

TL;DR: In this paper, the authors disclosed various types of TFT active matrix liquid crystal display devices and method of fabrication thereof in which a pixel is divided into three parts, a capacitor is added to each pixel, light shielding is applied to each TFT, and the matrix is driven by a DC cancelling technique.
Patent

Liquid crystal display device having smaller frame area

TL;DR: In this paper, the layouts of extraction lines DTM of drain wiring of a TFT liquid crystal display device, a driving IC of the display device and a flexible board FPC 2 for a drain driving circuit were improved.
Patent

Display device having driving circuit

TL;DR: In this paper, a display device with a drain driver mounted on a display substrate and having a gate driver and a controller therein, and also a power source mounted to a flexible printed board and supplying a power voltage to the gate driver is presented.
