摘要:
A display apparatus is implemented using an SOG or SOP technology that can integrate a plurality of circuit elements on a single substrate. The display apparatus does not include a separate frame memory. Instead of the separate frame memory, the display apparatus uses a predetermined region of a memory provided in a host by allocating it as a frame memory region. Since an image signal transmitted/received between the display apparatus and the host has a coded format, a chip size of the display apparatus and an information processing system with the same is reduced and an amount of transmission data is also reduced.

A liquid crystal display (“LCD”) device includes an LCD panel and a driving module. The LCD panel includes a plurality of pixel parts, each including a transmitting portion and a reflecting portion. The transmitting portion has a first switching element electrically connected to a first gate line, and a first liquid crystal capacitor electrically connected to the first switching element. The reflecting portion has a second switching element electrically connected to a second gate line, and a second liquid crystal capacitor electrically connected to the second switching element. The driving module applies a first common voltage to the first liquid crystal capacitor during turning-on of the first switching element, and applies a second common voltage to the second liquid crystal capacitor during turning-on of the second switching element. Therefore, an image display quality is improved.
摘要:
A liquid crystal display having a plurality of pixels and blocks of shift registers that are connected to one another for temporarily storing data signals and from which the data signal outputs are sequentially applied to drive the pixels. Each of the shift registers receives a shift start signal and at least one of first and second clock signals, of which phases are opposite to each other, and a high period of the shift start signal corresponds to two cycles of the respective clock signals so that each pixel is pre-charged from the data signal from previous block of registers before receiving the data signal for the current block thereby preventing a boundary between blocks from being visually recognized.
