20140160180 | VIDEO DISPLAY APPARATUS - Light leakage and black float are reduced in dark ambient while a perception of high contrast is achieved when a backlight is divided into a plurality of areas and backlight brightness is controlled depending on a video signal corresponding to each area. An area active control portion ( | 06-12-2014 |
20140160181 | VIDEO DISPLAY DEVICE - The present invention effectively suppresses not only occurrences of halos but also degradation of the black level. This image display device has a liquid crystal panel ( | 06-12-2014 |
20150161932 | VIDEO DISPLAY DEVICE - In the present invention, when a main screen and one or more secondary screens are displayed, the screen luminance for the main screen can be suitably controlled without being affected by video signal for the secondary screens. A video display device ( | 06-11-2015 |
20150363043 | TOUCH PANEL DEVICE AND TOUCH PANEL DEVICE CONTROL METHOD - A touch panel device ( | 12-17-2015 |
20160091919 | TOUCH PANEL SYSTEM AND ELECTRONIC DEVICE - In a touch panel system of the present invention, a touch pen is configured of an electronic pen that signals can be input into and output from. A touch panel controller includes a synchronization signal transmission unit that transmits a synchronization signal to the electronic pen during synchronization signal transmission periods immediately before each of a first signal line drive period and a second signal line drive period. The synchronization signal transmission unit transmits the synchronization signal of which the waveform is configured of a Manchester-coded pseudorandom sequence having periodicity to the electronic pen during the synchronization signal transmission period. The electronic pen includes a synchronization signal detecting unit that detects the synchronization signal. | 03-31-2016 |
20160110015 | TOUCH PANEL SYSTEM AND ELECTRONIC DEVICE - A touch panel system includes a touch panel which includes a plurality of horizontal signal lines and a plurality of vertical signal lines, a touch panel controller which controls the touch panel, and a touch pen. The touch panel controller drives the horizontal signal lines in one of successive two frame periods and drives the horizontal signal lines or the vertical signal lines in the other of the frame periods, the touch pen outputs a state signal about a state of the touch pen in each frame period, and a first item representing a state of the touch pen is expressed by a plurality of state signals which are outputted in a plurality of successive frame periods. | 04-21-2016 |
20160117019 | TOUCH PANEL SYSTEM AND ELECTRONIC DEVICE - In a touch panel system ( | 04-28-2016 |
20160139732 | TOUCH PANEL SYSTEM - A touch panel controller is equipped with a control unit that outputs a decimation signal to a drive line driving circuit when touch response magnitude data is a designated value or greater, or in other words, when the distance between a touch panel and a stylus pen is closer than a designated value. Thus, it is possible to realize a touch panel system able to moderate the amount of power consumed when synchronizing drive timings between the pen and the touch panel controller that drives the touch panel, and thereby operate with low power consumption. | 05-19-2016 |
