Claim 19:
20. The control method according to claim 19, wherein each row and each column in each matrix are respectively provided with a control line to receive a corresponding control signal,
sequentially controlling, according to the clock signal, each row of light sources in the matrix to emit light in the preset light-emitting interval according to the corresponding color and brightness information comprises: for a matrix with M rows and N columns in the one or more matrices,
acquiring a current clock signal,
determining the mth row of light sources corresponding to the current clock signal, m being a positive integer not greater than M,
activating the mth row control line in response to determining the mth row of light sources, and
for each of the mth row of light sources, controlling a column 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; and/or,

sequentially controlling, according to the clock signal, each column of light sources in the matrix to emit light in the preset light-emitting interval according to the corresponding color and brightness information comprises: for a matrix with M rows and N columns in the one or more matrices,
acquiring a current clock signal,
determining the nth column of light sources corresponding to the current clock signal, n being a positive integer not greater than N,
activating the nth column control line in response to determining the nth column of light sources, and
for each of the nth column of light sources, controlling a 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.
