The UMI-AMOLED screen analyzes

Super that the UMI use world leads AMOLED monitor, contrast degree Gao to be more than your imagination.The contrast degree that the normal regulations cellular phone holds generally is 400~1000 or so.Compare bottom, the good and bad signs to see.Contrast degree the important parameter that is a display. umi phone any high use world lead of Super AMOLED monitor, contrast degree Gao to be more than your imagination.The contrast degree that the normal regulations cellular phone holds generally is 400~1000 or so.Compare bottom, the good and bad signs to see.Contrast degree the important parameter that is a display.The contrast degree is more high, express display can the shown picture layer is more abundant.Each factory houses all make an effort to promote contrast degree to acquire a better sense of vision experience. The definition of the contrast degree of display is:In the dark room, under the white appearance(is the brightest) of bright degree in addition to the bright degree that descends by black appearance(is the darkest).Namely: From above the formula can see, promoting of contrast degree, nothing but promote the bright degree of white appearance, or is the bright degree that lowers black appearance.

Thebuy umi x1 bright degree of traditional LCD monitor is very high, but in whole black appearances is depend on the LCD member countercheck back light send out of ray, this principle comes to a decision ray to completely be covered, therefore leak light severity, the contrast degree can not get to effectively promote.But only depend on the bright degree that promotes white appearance to raise a contrast degree, would once result in strong ray's stimulating eyes and caused to see fatigue and even injured sight.To the cellular phone that use usually every day, the degree with bright increment obviously isn't a good way. Super of the UMI cellular phone AMOLED the monitor and traditional LCD hold and show that the principle is totally different, doesn't need to carry on the back light source, it shows that the unit oneself is a miniature and gives out light diode.While showing black appearance, black part to should of give out light a diode close then, therefore Super AMOLED is in the black appearance almost is don't give out light, can carry out a very high contrast degree. The unit of bright degree is to axe virtuous pull an each square meter of cd/m 2., The bright degree of the black appearance of the normal regulations LCD cellular phone generally goes to low a 0.5 cds/m 2, even if all of the adoption stick LCD of matching the technique, also can decline to a 0.25 cds/m 2.But the world of V981 adoptions lead of super AMOLED, black appearance the bright degree is low to go to a 0.0036 cds/m 2, almost want than LCD black 100 times!

The UMI X1 screen contrasts the influence of the degree upon the visual effect very key.The contrast degree is more high, picture layer more abundant, sense of vision feeling more clear and refreshing, the color is also more fresh clearly gorgeous;But if contrast degree shortage, then will let the whole appearance looks ash to receive of, was like to receive 1 F fog.The high contrast degrees all do a lot of good to the clear degree, detail performances and ash degree layer performances of the picture.The high contrast degree shows to the video frequency also helpful, in the dynamic state appearance clearly the dark conversion is quick, the contrast degree is more high, and the person's eyes more and easily distinguish one conversion process like this.See action big slice of with the UMI cellular phone, effect by long odds and common cellular phone.
