Abstract

Disclosed is a liquid crystal panel for 3D display, a driving method and a pixel optimization method thereof. The liquid crystal panel includes a display panel and an FPR film attached to a surface of the display panel. The FPR film is divided into first areas and second areas, the first areas and the second areas being arranged alternately in a direction parallel to lines of the sub-pixel units of the display panel, and each covering two lines of sub-pixel units. The liquid crystal panel can reduce the production cost of the 3D display device and improve the resolution.

Claims

1. A pixel optimization method of a liquid crystal panel for 3D display,

wherein the liquid crystal panel for 3D display comprises a display panel and a Film-type Patterned Retarder film attached to a surface of the display panel,

wherein the display panel is provided with orthogonally arranged multi-line, multi-column sub-pixel units;

wherein the Film-type Patterned Retarder film is divided into first areas for left-eye picture display and second areas for right-eye picture display, the first areas and the second areas being arranged alternately in a direction parallel to lines of the sub-pixel units, and the first areas and the second areas arranged alternately each covering two lines of sub-pixel units;

wherein the sub-pixel units present a PenTile arrangement;

wherein the liquid crystal panel for 3D display is displayed using a driving method of, during display of one frame of picture,

sequentially driving the sub-pixel units covered by the first areas and the second areas of the Film-type Patterned Retarder film arranged alternately;

displaying left-eye pictures using the sub-pixel units covered by the first areas, and

displaying right-eye pictures using the sub-pixel units covered by the second areas; and

wherein the pixel optimization method comprises;

employing Sub-Pixel Rendering algorithm to perform a virtual resolution compensation for received left-eye picture data and right-eye picture data.

2. The pixel optimization method according to claim 1, further comprising employing the Sub-Pixel Rendering algorithm to perform the virtual resolution compensation for the received left-eye picture data and right-eye picture data, respectively.

3. The pixel optimization method according to claim 1, wherein the pixel optimization method is applicable to full high definition display and ultra-high definition display.
