Abstract: Composite coatings that passively cool when exposed to the sky are provided. The composite coatings are suitable for increasing atmospheric condensation on a surface of a substrate. In particular, the composite coatings may be suitable for capturing atmospheric water. Also provided are methods for producing the composites coatings, methods for coating the surface of substrates with the composite coatings, methods for condensing and collecting atmospheric water, and systems for collecting condensed atmospheric water.

Abstract: A memory architecture of display device comprises a memory cell array having a plurality of memory cells arranged as a plurality of cell rows and a plurality of cell columns, and a data latch circuit having a plurality of latch units for storing a plurality of bits; wherein the number of the latch units is equal to that of the memory cells in each cell row, such that each bit stored in the data latch circuit can be written to each memory cell of one cell row at one time. The present invention also provides a memory writing method.

Abstract: A source driver for LCD devices, used for driving at least one data line, comprises an input for receiving a predetermined voltage; an output electrically being connected to the data line and having an output voltage; a voltage clamping circuit for clamping the output voltage within a predetermined voltage range; a first differential amplifier for increasing the clamped output voltage toward the predetermined voltage; and a second differential amplifier for decreasing the clamped output voltage toward the predetermined voltage. The present invention also provides a source driving method for LCD devices.
