An anti-glare optical film which reduces in whitening of a screen without sacrificing anti-glare property, and a process for preparing the same. There is provided an anti-glare optical film has an irregular surface, wherein a ratio of areas of the surface having an inclination angle of 1° or less is 20% or less, a ratio of areas of the surface having an inclination angle of 5° or more is 20% or less, and a standard deviation of a height of the surface is 0.2 μm or less. There is also provided a process for preparing an anti-glare optical film.

The invention discloses a method for improving the display state of a liquid crystal panel. The method includes the following steps that: the storage capacitance values of a far-end sub-pixel unit, an intermediate sub-pixel unit and a near-end sub-pixel unit on a gate signal line of the array substrate of the liquid crystal panel are obtained; the storage capacitance values of the far-end sub-pixel unit and the near-end sub-pixel unit are adjusted, so that voltage drop caused by the capacitive coupling effect of the far-end sub-pixel unit and the near-end sub-pixel unit is the same as voltage drop caused by the capacitive coupling effect of the intermediate sub-pixel unit; and the storage capacitance values of far-end sub-pixel units and near-end sub-pixel units on the other gate signal lines are correspondingly adjusted according to the adjusted storage capacitance values of the far-end sub-pixel unit and the near-end sub-pixel unit. With the method adopted, uneven brightness of a liquid crystal panel frame or the whitening of two sides of a module set can be improved, and therefore, the display quality of the liquid crystal panel can be improved.
