Patent ID: 8502929

Claim:
A display apparatus, comprising: a backlight module, having a plurality of light-emitting regions capable of emitting light individually; a liquid crystal panel, disposed at a side of the backlight module; and a controller, electrically coupled to the backlight module and the liquid crystal panel, wherein when the liquid crystal panel updates a left-eye image to a right-eye image row by row along a column-direction, the controller sequentially turns on and off the light-emitting regions along the column-direction, such that a whole region of the liquid crystal panel lighted by each of the light-emitting regions displays the left-eye image or the right-eye image, a number of the light-emitting regions is n, a frame time of the liquid crystal panel is T, a time occupied by a display region of the liquid crystal panel within one frame time is Ta, a time for waiting liquid crystal molecules to be stable is Tc, a turned-on time length of each of the light-emitting regions is Tt, an overlapping time that adjacent light-emitting regions are all in a turned-on state is To, wherein n, T, Tc, Ta, Tt and To are positive numbers, and Tt=T−(n−1)*(Ta/n)−Tc, and To=Tt−(Ta/n), an x-th light-emitting region is turned on after a signal of a Txs-th scan line is updated when the liquid crystal panel is started to be updated to the right-eye image, the x-th light-emitting region is turned off after a signal of a Txe-th scan line is updated when the liquid crystal panel is started to be updated to the right-eye image, and a proportion that a region of the liquid crystal panel lighted by each of the light-emitting regions covers an area of any adjacent light-emitting region is m %, Txs, Txe and m are positive numbers, and x is a positive integer from 1 to n, and Txs=[(x+m %)*(Ta/n)]+Tc, and Txe=Txs+Tt.
