Abstract: The present invention proposes a driving circuit and a shift register. The driving circuit includes shift register circuits disposed in cascade. Each of shift register circuits includes a clock control transmittance circuit and a latch circuit. The clock control transmittance circuit is triggered by a first clock pulse. A driving pulse of a Q node at previous two stages is transmitted to the latch circuit and latched by the latch circuit. Further, the latch circuit is triggered by a second clock pulse, and then a gate driving pulse and a driving pulse of the Q node is output. So the present invention can be used in the CMOS process owing to the features of low consumption and wide noise margin.

Abstract: A method for manufacturing an eye-protecting liquid crystal display device is disclosed, in which an ultraviolet light emitting material and a ultraviolet absorbent are added in a first planarization layer of an array substrate and a second planarization layer of a color filter substrate. The ultraviolet absorbent absorbs short-wavelength blue light having a wavelength less than 400 nm and ultraviolet light emitting from a backlight module. The short-wavelength blue light and the ultraviolet light so absorbed excite the ultraviolet light emitting material to give off long-wavelength visible blue light having a wavelength greater than 400 nm. The first and second planarization layers are thus useful in converting ultraviolet light and short-wavelength blue light having a wavelength less than 400 nm, which could damage human eyes, into long-wavelength visible blue light having a wavelength greater than 400 nm that does not damage human eyes.

Abstract: The present invention proposes a touch panel display device and an array substrate. A touch panel display device includes a touch detecting circuit, touch detecting electrodes, and transmission paths. One terminal of each of the transmission paths is connected to one of the touch detecting electrodes, and the other terminal of each of the transmission paths is connected to the touch detecting circuit, for transmitting a touch signal of the touch detecting electrode to the touch detecting circuit. A difference of variation for each touch signal of the touch detecting electrodes is smaller than a first predetermined value after being transmitted through each of the transmission paths. The first predetermined value is a threshold by which false identification occurs among the touch signals from the touch detecting electrodes. The present invention improves sensitivity of touch.

Abstract: A blue phase liquid crystal panel includes a plurality of pixel cells. Each of the pixel cells comprises a display area and a viewing angle controlling area. The viewing angle controlling area includes a plurality of first electrode pairs spaced apart from each other, and each of the first electrode pairs includes a first pixel electrode1 and a first common electrode. In a wide viewing angle mode, no electrical field is generated by the first electrode pair of the viewing angle controlling area. In a narrow viewing angle mode, a vertical electrical field is generated between the first pixel electrode and the first common electrode of each of the first electrode pairs within the viewing angle controlling area. In this way, the liquid crystal panel may transit between the wide viewing angle mode and the narrow viewing angle mode.
