Light-emitting substrate

A light-emitting substrate, comprising:

• a base substrate;
• and
• a plurality of light-emitting units and a plurality of first driving signal line groups on the base substrate,
• wherein each of the light-emitting units comprises a plurality of light-emitting sub-units, and each of the light-emitting sub-units comprises a first electrode terminal and a second electrode terminal, a polarity of the second electrode terminal being opposite to a polarity of the first electrode terminal;
• each of the first driving signal line groups comprises at least one first driving signal line, and the first driving signal line is configured to be connected to the first electrode terminal of the light-emitting sub-unit to provide a first electrode signal;
• the plurality of light-emitting units are arranged in a plurality of columns and a plurality of rows along a row direction and a column direction, respectively;
• the plurality of light-emitting sub-units in each of the light-emitting units comprise a first light-emitting sub-unit, a second light-emitting sub-unit, and a third light-emitting sub-unit, the first light-emitting sub-unit and the second light-emitting sub-unit are arranged adjacent to each other in the row direction, the third light-emitting sub-unit is arranged side by side with the first light-emitting sub-unit and the second light-emitting sub-unit in the column direction, and the first light-emitting sub-unit, the second light-emitting sub-unit, and the third light-emitting sub-unit are configured to provide light of different colors respectively;
• among an N-th column of light-emitting units and an (N+1)-th column of light-emitting units, a translational distance, in the column direction, is provided between a k-th light-emitting unit in the N-th column of light-emitting units and a k-th light-emitting unit in the (N+1)-th column of light-emitting units, and the translational distance is smaller than a spacing between two adjacent light-emitting units in a same column in the column direction, so as to allow light-emitting units in the N-th column and the (N+1)-th column to be respectively located in different rows in sequence, wherein N and k are positive integers greater than 0;
• each of the first driving signal line groups is between the N-th column of light-emitting units and the (N+1)-th column of light-emitting units, and the first driving signal line group is in a zigzag extension along the column direction and alternately passes through a light-emitting unit of an M-th row and the N-th column, a light-emitting unit of an (M+1)-th row and the (N+1)-th column, and a light-emitting unit of an (M+2)-th row and the N-th column, so as to provide the first electrode signal to the light-emitting units in the N-th column and the (N+1)-th column, wherein M is a positive integer greater than 0;
• and
• each of the light-emitting units is passed by two adjacent first driving signal line groups,
• wherein the light-emitting sub-unit is a light-emitting diode chip.
