Patent ID: 8872866

Claim:
A method for controlling pixel brightness of a 3D display panel, the 3D display panel comprising a plurality of first viewing angle pixels arranged along a first direction for displaying first viewing angle images, and a plurality of second viewing angle pixels arranged along the first direction for displaying second viewing angle images, the plurality of first viewing angle pixels and the plurality of second viewing angle pixels being interlacedly arranged along a second direction, and each of the first and second viewing angle pixels comprising a first block and a second block, the first block and the second block of the first viewing angle pixel having the same fixed viewing angle, the first block and the second block of the second viewing angle pixel having the same fixed viewing angle different from the first viewing angle, the method comprising: determining a brightness value of a first block of a first viewing angle pixel according to a predetermined brightness value of the first viewing angle pixel and a predetermined brightness value of a second viewing angle pixel next to the first viewing angle pixel along the second direction; determining a brightness value of a second block of the first viewing angle pixel according to the predetermined brightness value of the first viewing angle pixel and the brightness value of the first block of the first viewing angle pixel; and generating a reference value by subtracting a maximum brightness value of the second block of the first viewing angle pixel and a minimum value of the predetermined brightness values of the first and the second viewing angle pixels multiplied by an area ratio between the first block and the first viewing angle pixel from the predetermined brightness value of the first viewing angle pixel.
