A liquid crystal driver circuit may include a screen including a plurality of liquid crystal units distributed as an array. The array may include m rows of liquid crystal units along a row direction, and n columns of liquid crystal units along a column direction, wherein m is an integer and n is an integer. The screen may also include n data lines, respectively connected to the n columns of liquid crystal units along the column direction; and at least one data line switch, each connected to a corresponding data line of the n data lines.
