Problems solved by technology
At this time, because the idle time during the subframe cannot be efficiently used, the light source will be used less efficiently
In addition, the brightness perceived by the human eye is related to the duration of the backlight, so the reduction of the optical display time may make the display frame only have a lower brightness

Embodiment Construction
[0039] Figure 2A A block diagram of a color sequential display according to an exemplary embodiment of the present invention is shown. Figure 2B drawn according to Figure 2A A schematic diagram of the display steps of the color sequential display of the exemplary embodiment. Please refer to Figure 2A and Figure 2B , the color sequential display 200 displays frames during a frame period 110 . A frame includes a plurality of subframes with different colors. These sub-frames are displayed switched on the time axis (that is, the so-called time domain). In other words, these subframes are individually displayed in the subframe periods 111-114 in the frame period 110, that is, the red subframe R is in the subframe period 111, the green subframe G is in the subframe period 112, and the blue subframe B is in the subframe period 113 , and the compensation subframe is in the subframe period 114 .

The invention discloses a color sequence display and a display method thereof. The color sequence display displays a frame in a frame period. The frame comprises a plurality of sub frames, and the frame period comprises a plurality of sub frame periods corresponding to the plurality of sub frames. The display method comprises the following steps of: starting a first color light source to display the first sub frame according to a first working cycle in the first sub frame period; then, starting a second color light source to display the second sub frame according to a second working cycle in the second sub frame period; and finally, starting the first color light source corresponding to a first correcting working cycle and a second color light source corresponding to a second correcting working cycle in a complementary color sub frame period to display a complementary color sub frame respectively. The first correcting working cycle and the second correcting working cycle are in proportion to the first working cycle and the second working cycle.
Description
technical field [0001] The present invention relates to a color sequential display and its display method, and in particular to a method for adjusting the duration of different color frame periods during display. Background technique [0002] With the maturity of optoelectronic and semiconductor process technologies, the development of flat panel displays is quite rapid. Liquid crystal displays (Liquid crystal displays, LCD) have the advantages of low operating voltage, no radiation, and light weight, so they are gradually replacing traditional cathode ray tube TVs in the mainstream display product market. The LCD mainly includes a liquid crystal (liquid crystal) panel and a backlight module. Since the liquid crystal panel injected with liquid crystal cannot emit light by itself, the liquid crystal panel must pass through the planar light source of the backlight module to emit light, so as to activate the LCD display. [0003] Traditionally, a white light source is configu...
