Data driving circuit and display apparatus

The present disclosure relates to a data driving circuit and a display apparatus. The data driving circuit includes a shift register, a first latch circuit, a second latch circuit, a level shift circuit, a DA converting circuit, and an output circuit. The first latch circuit samples digital data to obtain a sampled signal based on a sampling pulse signal. The second latch circuit detects that a boundary value of the current sampling pulse signal in a specified range. When the boundary value of the current sampling pulse signal in the specified range is different from the boundary value of the previous sampling pulse signal, a compensation signal is effective, and the output circuit controls the voltage of the corresponding data line to be set at a specified voltage according to the compensation signal before the driving voltage of the corresponding data line being applied.
