Latest Patents

Dewa's latest patents include a liquid crystal display apparatus and a cooling device. The liquid crystal display device is designed to constrain the injection of air bubbles in a cooling fluid into a display panel. In this device, the cooling fluid is supplied to a receiving space of a receiving unit that is placed opposite the surface of a liquid crystal panel. This setup allows for effective cooling of the liquid crystal panel by utilizing a cooling fluid pump. The cooling fluid is drained from a drain port and supplied from a feed port to the receiving unit. A flow path block unit is strategically placed to disperse the flow of the cooling fluid around it.

Another notable patent is a liquid crystal display that features a dummy bump connected to a dummy lead for heat reduction. This display is intended for use in an LCD projector and includes a liquid crystal display panel with a TFT substrate and a counter substrate. The flexible film substrate is electrically coupled to the display panel and contains multiple leads, including at least one dummy lead. The driving IC, which is responsible for driving the liquid crystal display panel, is also disposed on the film substrate and features at least one dummy bump connected to the dummy lead, which serves a heat-releasing function.
