    摘要: A pixel circuit includes a data writing and compensation sub-circuit, a driving sub-circuit, and a light-emitting control sub-circuit. The data writing and compensation sub-circuit is configured to transmit a data signal from a data voltage terminal to the driving sub-circuit under control of a first control signal terminal, and to compensate a threshold voltage of the driving sub-circuit under the control of the first control signal terminal. The light-emitting control sub-circuit is configured to transmit a first voltage signal from a first voltage terminal to the driving sub-circuit and the data writing and compensation sub-circuit under control of a second control signal terminal, and to transmit a second voltage signal from the second voltage terminal to the driving sub-circuit under the control of the second control signal terminal. The driving sub-circuit is configured to transmit a signal output from the light-emitting control sub-circuit to a light-emitting sub-circuit.

    摘要: A display substrate, a short-circuit detecting method, and a display device are provided. The display substrate includes: a plurality of touch control electrodes, a plurality of touch control signal lines, a voltage receiving end, and a plurality of switch circuits. The plurality of touch control electrodes are divided into a plurality of test groups. Each of the touch control electrodes belongs to one of the plurality of test groups. Each of the switch circuits is connected to all touch control electrodes in a test group through the touch control signal line. The switch circuit is configured to switch a connection state between the connected touch control electrodes and the voltage receiving end under the control of the connected switch control signal. Based on the structure of display substrate, it is possible to detect whether there is a short circuit between the touch control electrodes in the electrical test.
