Therefore, existing large-sized display panels designs all towards the mode of (3) bilateral driving, reduces the impact of resistance capacitance effect.Because the influence degree of resistance capacitance effect can reduce half, therefore effect is very remarkable.But need to increase double driven unit, thereby must additionally increase considerable cost.Moreover in the time that this LCD board size is increased to a certain degree, the improvement mode of the bilateral driving of existing use, because monolateral resistance capacitance effect is obvious gradually, still can cause the problem that this display panels is upper and lower and central brightness is inhomogeneous, as shown in Figure 3.Thus, although increase cost also cannot effectively improve the awkward situation of brightness irregularities.
