  • Patent number: 8175146
    Abstract: In a data compensating circuit and a display apparatus having the same, a previous compressed data compressed from a previous frame data is previously stored in a memory, a decoder decompresses the previous compressed data from the memory to output a previous decompressed data, a coder-decoder compresses a present frame data into a present compressed data to store the present compressed data in the memory and decompresses the present compressed data to output a present decompressed data. A first processor outputs a difference value between the previous decompressed data and the present decompressed data, a second processor adds the present frame data and the difference value to generate a previous re-decompressed data. A compensator outputs a present compensation data based on the previous re-decompressed data and the present frame data. Thus, the size of the memory may be reduced while preventing damage of data.

  • Patent number: 8148916
    Abstract: A light source module includes a plurality of light-emitting blocks. A local-dimming driver drives the light-emitting blocks based on a received clock signal (first reference clock) and received dimming levels. The clock signal is input to a liquid crystal display panel and is also input to the local-dimming driver but is delayed within the local-dimming driver by fixed propagation delay. A delay modeling part performs modeling of the fixed propagation delay amount. The clock signal input to the local-dimming driver is first phase-compensated (delayed) by a phase compensation amount to synchronize the driving signals output by the local-dimming driver with the clock signal. The sum of the modeled propagation delay amount and the phase compensation amount is equal to an integral multiple of the period of the clock signal. The driving signal of the light-emitting blocks are synchronized and in phase with the clock signal.
