Abstract: A display apparatus includes a first light source, a second light source, a third light source, a first color filter, a second color filter, a third color filter, and an opto-functional device. The first light source and the second light source are allowed to emit light in a first emission time period to form a first display pattern. The third light source is allowed to emit light and the opto-functional device controls the third color filter to transmit light in a second emission time period to form a second display pattern. The first emission time period and the second emission time period are alternately repeated to combine the first display pattern and the second display pattern to obtain an intended display pattern when the display apparatus displays the intended display pattern.
