1. An apparatus for reducing an erroneous color effect in a field-sequential liquid crystal display (FSLCD), the apparatus comprising:

  • a data response time compensation (RTC) block configured to receive sequential display signals, wherein the data RTC block is also configured to use an RTC lookup table to provide a fast transition response time from one gray level to another gray level for a liquid crystal pixel cell by using a response time compensation (RTC) scheme during a color LED backlighting sequence;

    a VCOM and Gamma reference control block configured to generate a voltage boost and provide boost control to the liquid crystal pixel cell in a FSLCD panel operatively connected to the VCOM and Gamma reference control block, wherein the voltage boost gives a fast gray level transition to remove residual color caused by a slow transition time between liquid crystal light transmittance levels for the liquid crystal pixel cell; and

    an output interface for the RTC block and/or the VCOM and Gamma reference control block, wherein the output interface is configured to transmit manipulated sequential display data from the RTC block and/or the output interface is configured to transmit a boosted voltage control signal from the VCOM and Gamma reference control block.
