Abstract: Provided are a driver board, a display panel, and a display apparatus. The driver board includes a driver circuit. The driver circuit includes N pixel electrodes, N pixel switches, a data switch, and a storage capacitor, N is a positive integer, and N≥2. The storage capacitor includes a reference electrode and a counter electrode. A control terminal of the pixel switch receives a gating signal, a first terminal of the pixel switch is connected to the counter electrode, and a second terminal of the pixel switch is connected to the pixel electrode. The driver board further includes data lines, and each data line is connected to the counter electrode via the data switch.
