The display device includes a signal processing module and a display panel. The signal processing module includes a memory that is divided into two or more sub-memories that can be powered on separately, and an image signal processor to generate a second image signal from a first image signal using the memory.

Power is selectively supplied to the sub-memories according to the bit size of the first image signal.

Abstract: A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.

Abstract: A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n?1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n?1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.

Abstract: A gate drive portion for a display device including multiple pixels having first and second sub-pixels includes a first shift register generating a first output signal in response to a first gate clock signal, a second shift register generating a second output signal in response to a second gate clock signal, a level shifter coupled to the first and second shift registers and amplifying the first and second output signals, and an output buffer coupled to the level shifter and generating first and second gate signals. The first gate signal is generated in synchronization with the first gate clock signal and the second gate signal is generated in synchronization with the second gate clock signal. Accordingly, the charging time of the first and second sub-pixels may be improved by separately driving the odd-numbered and even-numbered sub-pixels and the visibility of the LCD device may also be improved.

The LCD device includes a timing controller generating an output enable signal and a gate clock, where the timing controller adjusts a timing of a load signal for deciding a data output timing point when data will be loaded into a currently activated display row. The data output timing point is a function of a delay measuring feedback signal that is used to measure the cumulative delays of the sequentially connected stages of the shift register.

Abstract: In a driving device and a display apparatus having the driving device, a converter converts input image data and outputs first and second sub-image data which have different values. A first compensator compensates the first sub-image data and outputs a first compensated image data, and a second compensator compensates the second sub-image data and outputs a second compensated image data. An output circuit controls output time of the first and second compensated image data. Accordingly, sub-image data for each sub-pixel may be exactly compensated by employing compensators to individually compensate for the sub-image data of each sub-pixel.

The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n?1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n?1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.
