Research on the LCD splicing screen optical seam elimination effect improvement and cost reduction

The side of the lens placed in the AA region has distortion and a large lateral vision dark in the part of the lens. Cut one lens into two from the middle and place them at the seams of screens to achieve seam elimination. The darkened area of the picture is smaller, while reducing costs. Further, because this traditional lens usually needs to open a separate mold, the cost of mold opening is high, and it is difficult to match the seam elimination of various cases in one mold, thereby increasing the cost. The electronically controlled liquid crystal lens does not need to open the mold, and the production cost is low. The use of electronically controlled liquid crystal lens can further reduce the cost, and the scheme is simulated and verified.
