A trigate panel, comprising several pixel units, the pixel units containing three sub-pixel units representing different colors, and a thin film transistor is disposed on each of the pixel units, a source electrode of the thin film transistor is connected to the charging electrode of each sub-pixel via self-capacitance of the sub-pixel unit. Scanning lines (G1, G2, , G2n, G(2n-1))are sequentially disposed along a first direction of the panel to connect to the gate of each thin film transistor on the sub-pixel unit. Data lines (D1, D2, , Dm) are disposed along a second direction of the panel to connect to a drain of the thin film transistor disposed on the sub-pixel unit. A fan-out area comprises a plurality of fan-out lines, an output terminal of each of the fan-out lines being aligned with the scanning lines, and being connected to respective scanning lines in a paired and crossing arrangement. The trigate panel reduces charging difference of sub-pixels of different colors, thus avoiding color shift of two sides of a mixed color picture, improving display effect, simultaneously relaxes the restrictions of source side fan-out area impedance during design, thus facilitating the design of narrow borders.
