Claim 23:
24. The control method according to claim 21, wherein when each light source comprises the light-emitting diodes connected in parallel to the same column control line, each row control line in each matrix comprises parallel sub-row control lines, and
for each of the nth column of light sources, controlling the row control line corresponding to the light source according to the color and brightness information corresponding to the light source, so that the light source emits light in the preset light-emitting interval according to the corresponding color and brightness information comprises: for the m′th light source in the nth column of light sources, m′ being a positive integer not greater than M,
determining, according to the color information corresponding to the light source, to activate which sub-row control lines among the (a(m′−1)+1)th sub-row control line to the (am′)th sub-row control line corresponding to the light source, and
determining, according to the brightness information corresponding to the light source, activation periods of some sub-row control lines that are determined to be activated in the preset light-emitting interval,
wherein the higher the brightness indicated by the brightness information corresponding to the light source is, the longer the activation periods of some of the sub-row control lines in the preset light-emitting interval.
