Width is A0The waveform of light S1, it is A that dotted line S2 represents amplitude0The waveform of light S2, dotted line S ' represents light S1 and light S2 vibration and strengthens
After waveform.Amplitude A due to light S10Amplitude A with light S20Meet at C point and always vibrate reinforcement at C point, thus at C point
Realizing interference the longest, its amplitude obtained after being overlapped is 2A0, owing to the light intensity at C point is (2A0)2, with unrealized interference
Time mutually long, the light intensity phase specific luminance at C point enhances, and therefore, it can make the brightness of pixel subelement 100_1 to increase, and then makes picture
The color of sub-prime unit 100_1 is more bright-coloured.
As it is shown in figure 1, when light S1 and light S2 is from air incidence to transflective layer 230_1, the light of light S1 and light S2
Path difference Δ L is the integral multiple of its wavelength X, i.e.Wherein k is positive integer, i.e.Such that it is able to it is the longest to make light S1 and light S2 interfere when meeting at C point.
Being to have a range of generally as the wavelength of light of sub-prime unit display corresponding color, such as pixel subelement is
