Latest Patents

Hirano's latest patents include a "Device and method for internal horizontal sync signal generation." This invention involves a display driver that comprises a timing controller and a drive circuit. The timing controller receives an external horizontal sync signal and generates an internal horizontal sync signal based on it. The drive circuit then drives a display panel in synchronization with the internal horizontal sync signal. The process of generating the internal horizontal sync signal includes creating a first pulse in response to the detection of a first pulse of the external horizontal sync signal after a masking period has expired. Additionally, a second pulse is generated in response to the detection of a second pulse of the external horizontal sync signal during a non-masking period.

Another significant patent is the "Positioning apparatus and positioning method." This apparatus features a display that shows a first map representing the position of the apparatus obtained from a first positioning. It also displays a second map representing the position obtained from a second positioning, which starts before the first map is displayed. The second map is shown without requiring a request for its display.
