Abstract: A capacitive touch sensor assembly that includes multiple regions is provided herein. Each of the multiple regions may include a top and a bottom array of patterned conductive material, such as indium tin oxide. The touch sensor assembly may further include a separate controller for each region, wherein the patterned conductive material in each region is coupled to the controller associated with that region. In one configuration, the top array of each region may not be aligned with the associated bottom region, such that multiple controllers may sense touches at a single point. Further, the patterned conductive material may include a plurality of rows and columns of diamond-shaped electrodes, wherein all of the electrodes have substantially the same surface area.

Abstract: An exemplary backlight module (23) includes a light guide plate (232) having a bottom surface (2321) and a light incident surface (2322) adjacent to the bottom surface, a light source (230) disposed adjacent to the light incident surface of the light guide plate and a reflective film (231) disposed adjacent to the light guide plate. The reflective film faces the light source and abuts the bottom surface of the light guide plate. The reflective film includes a reflective layer (2313) and a metal shielding layer (2315). A liquid crystal display device using the backlight module is also provided.

Abstract: An exemplary driving circuit of an active matrix liquid crystal display (LCD) (2) having an LCD panel includes a gate driving circuit (22), a data driving circuit (23), a timing control circuit (21), and a detecting circuit (21). The data driving circuit provides a plurality of gradation voltages to the LCD panel. The detecting circuit (28) is configured for detecting a first voltage difference between a pixel electrode and a common electrode in a first frame, detecting a second voltage difference between the pixel electrode and the common electrode in a second frame, generating an adjusting instruction according to a difference between the first voltage difference and the second voltage difference, and providing the adjusting instruction to the timing control circuit. The timing control circuit controls the data driving circuit to change a gradation voltage according to the adjusting instruction before an inverted gradation voltage is provided to LCD panel.
