    Abstract: The present invention discloses a local backlight brightness adjustment method for a direct backlight in a display device, the method comprising the steps of: step 1: performing edge detection on an input image to determine whether a sensitive zone exists, the sensitive zone being a portion in the input image in which a gray level difference between adjacent pixels is greater than a predetermined threshold; and Step 2: if a sensitive zone exists, performing a backlight brightness adjustment with respect to a backlight region corresponding to the sensitive zone and a remaining backlight region other than the backlight region corresponding to the sensitive zone, respectively. According to the above-mentioned technical solution, since the backlight brightness adjustment are performed with respect to the backlight region corresponding to the sensitive zone and the remaining backlight region other than the backlight region corresponding to the sensitive zone, respectively, thus, when there is gray level abruptly-varying portion in the image, the display performance of the displayer can still be ensured.

    Abstract: A thin film transistor array substrate, a driving method therefore, and a liquid crystal display are disclosed. The thin film transistor array substrate includes at least a sub-pixel region formed by a gate line and a data line intersected with each other, wherein, each sub-pixel comprises a first transistor (21) of which the gate is connected with a gate line and the drain is connected with a data line and a first storage capacitor (23) of which one end is connected with the source of the first transistor (21) and the other end is connected with an output of a reference voltage, the sub-pixel further comprises a second storage capacitor (24) and a second transistor (25), wherein one end of the second storage capacitor (24) is connected with the source of the first transistor (21), and the other end of the second storage capacitor (24) is connected with the drain of the second transistor (25); the source of the second transistor (25) is connected with the output of the reference voltage, and the gate of the second transistor (25) is connected with an output of an Enable signal. Since a second storage capacitor (24) is additionally added to each sub-pixel in the thin film transistor array substrate, the capacitance of the storage capacitors during static display is increased, the voltage conversion frequency during static display is deceased, and the system power consumption is decreased.

    Abstract: A double-sided display device includes: a first display layer, configured to implement output of a display signal of a first side; and a second display layer, configured to implement output of a display signal of a second side; a conversion layer positioned between the first display layer and the second display layer, which switches between a light-transmitting state and an opaque light-shielding state. The conversion layer is in the light-shielding state during a display phase, and in the light-transmitting state during an interfering phase which follows the display phase. During the interfering phase, the first display layer is further configured to output a first interfering signal to interfere with the image displayed by the second side, and the second display layer is further configured to output a second interfering signal to interfere with the image displayed by the first side.

    Abstract: A display panel, a display device, a manufacturing method and driving method thereof are provided. The display panel includes a light transmittance adjusting layer and two pixel layers being respectively located on opposite surfaces of light transmittance adjusting layer. Each of the pixel layers includes multiple light-emitting units arranged in an array. Orthogonal projections of two pixel layers on the light transmittance adjusting layer do not overlap. When light transmittance of light transmittance adjusting layer is higher, light emitted from the light-emitting units on both surfaces of light transmittance adjusting layer is emergent from opposite sides through light transmittance adjusting layer. Two pixel layers display the same picture jointly. When light transmittance of light transmittance adjusting layer is lower, light emitted from light-emitting units on both surfaces of light transmittance adjusting layer cannot be transmitted through light transmittance adjusting layer to reach opposite sides. Two pixel layers display images independently.
