Description

technical field [0001] The invention relates to image display technology, in particular to a liquid crystal box, a point-by-point control device, equipment and method. Background technique [0002] In an existing class of 2D / 3D switchable stereoscopic displays (referring to Chinese patent application publication CN 101387758A published on March 18, 2009), a block such as figure 1 The shown TN cell is used as an optical switching device, and the polarization direction of outgoing light is controlled by applying a voltage to the TN cell, thereby realizing switching between 2D and 3D displays. Obviously, once the TN box is switched, it will switch over the entire screen, and cannot perform point-by-point switching of 2D / 3D. [0003] In order to solve the above problems, another type of existing 2D / 3D switchable stereoscopic display uses a thin film transistor (Thin Film Transistor, TFT) type TN box as an optical switching device, because the TFT type TN box can perform switchi...
