1. a display unit, comprising:

  • Display floater;

    Computing and correcting circuit, it is configured to be similar to the input luma data of arithmetic expression to target frame image by useCarry out gamma correction, to produce output luma data;

    Drive circuit, it is configured with according to described output luma data, drives described display floater;

    WithCorrection data counting circuit, it is configured and produces the check point data group being made up of multiple check point data,Wherein, described correction data counting circuit is according to described input luma data or the described target of described target frame imageThe input luma data of the preceding frame image before two field picture, produces described check point data group, to make described multiple schoolData specify the shape of the gamma curve of described gamma correction on schedule,Wherein, described computing and correcting circuit, according to described multiple check point data of described check point data group, are determined instituteState the coefficient of approximate arithmetic expression,Wherein when the maximum of described input luma data is DINMAXWith the maximum of described output luma data be DOUTMAXTime,The described check point data group producing by described correction data counting circuit comprises by following equation (1a) or (1b) definitionCheck point data CP0 to CP5;

    CP0=
