摘要： A moisture resistant pad for a liquid crystal panel, including at least one moisture resistant construction including a central region and an edge region disposed around the central region, wherein the edge region includes a first undulation structure disposed around the central region, the first undulation structure being a closed structure for blocking water vapor out of the central region. In the moisture resistant pad for a liquid crystal panel, channels formed within a surface of a product that needs to be moisture resistant are isolated from the external environment so that water vapor in the external environment cannot contact the product surface through the channels. As a result, the pad has good moisture resistance, suitable in transportation environments or in packaging container environments.

摘要： The present invention provides a source driver for use in a TFT-LCD, comprising: a data register, a data latch, a digital-to-analog converter and an output buffer. A first loading pulse is provided to the output buffer, such that the output buffer starts to output the gray-scale voltages of odd output ends to corresponding TFT sources in response to a second edge of the first loading pulse from the second level to the first level, which second edge immediately follows the first edge, and a second loading pulse is provided to the output buffer, such that such that the output buffer starts to output the gray-scale voltages of even output ends to corresponding TFT sources in response to a second edge of the second loading pulse from the second level to the first level, which second edge immediately follows the first edge. At least the second edge of the first loading pulse is not synchronous with the second edge of the second loading pulse. A driving circuit and a driving method are further provided.

摘要： The present invention discloses an in-cell touch panel, a manufacturing method thereof and a display device. A plurality of nanowire arrays are added between an array substrate and an opposite substrate, nanowires in each nanowire array extend in a direction perpendicular to the array substrate and the opposite substrate; the newly-added nanowire arrays and s pacers provided between the array substrate an d the opposite substrate form piezoelectric sensitive elements. Thus, when cell thickness between the array substrate and the opposite substrate is slightly changed due to pressure on the touch panel by any object, a nanowire array may be slightly deformed by squeeze of a spacer, the deformed nanowire array may release charges to change an electrical signal applied to an electrode wire connected thereto, and a touch point can be positioned by detecting a change in the electrical signal, thus achieving high touch sensitivity.
