Signal control apparatus and method, display control apparatus and method, and display apparatus

A signal control apparatus for a display apparatus, the display apparatus comprising M rows*N columns of pixel driving circuits arranged in an array, wherein the M pixel driving circuits of each column of pixel driving circuits are divided into k groups, wherein k is greater than or equal to 2 and less than N, the ith pixel driving circuit of each column of pixel driving circuits is assigned to the [i Module k]th group, and the same group of pixel driving circuits are connected to a same data line to receive a data signal, and data lines connected to different groups of pixel driving circuits are different, the signal control apparatus comprising:

• a phase shifting circuit configured to provide a scanning signal to a pixel driving circuit to cause the pixel driving circuit to enter a data signal writing phase, wherein a phase difference between scanning signals of adjacent two pixel driving circuits in a same group of pixel driving circuits in a same column of pixel driving circuits is T, and a phase difference between scanning signals of adjacent two pixel driving circuits in the same column of pixel driving circuits is T/k, and T is a duration of the data signal writing phase of each pixel driving circuit;
• a write control circuit connected to a data signal terminal, and configured to provide a data signal from the data signal terminal to the pixel driving circuit for a data writing period of Ti=T/k;
• and
• a matching control circuit connected to the phase shifting circuit and the write control circuit, and configured to control the write control circuit to provide the data signal to a pixel driving circuit that receives a scanning signal when the phase shifting circuit provides the scanning signal to the pixel driving circuit.
