Embodiment
To make those skilled in the art more fully understand technical scheme, come below in conjunction with the accompanying drawings to the present invention
The display methods of the display module of offer and the display methods of display device are described in detail.
Referring to Fig. 1, display module 101 includes viewing area 102, the fingerprint that the viewing area 102 includes being disposed therein is known
Other area 102a, and remaining region 102b in addition to fingerprint identification area 102a.Moreover, in the present embodiment, such as Fig. 2 institutes
Show, fingerprint identification area 102b includes 6 sub-regions that are divided successively from fingerprint identification area 102b center to border, respectively the
The subregion of 0 subregion~the 5th.Wherein, the shape of the 0th subregion is similar to fingerprint identification area 102b shape, as rectangle, and
Positioned at fingerprint identification area 102b center, and other subregions are straight-flanked ring.
In the display methods of existing display module, as shown in figure 3, in fingerprint recognition, the 0th subregion~5th is sub
The display brightness in region is 500nits, and remaining region 102b in addition to fingerprint identification area 102a (such as shows in Fig. 2
The display brightness of the subregion 6 gone out~8) is 0.As shown in figure 4, in normal display, the subregion of the 0th subregion~the 5th it is aobvious
Show that brightness is equal with remaining region 102bb (such as the subregion 6~8 shown in Fig. 2) display brightness, be 350nits.On
State display brightness to refer to when display module is luminous using OLED, the light intensity that OLED is sent.
The display methods of above-mentioned existing display module is inevitably present problems with actual applications：Due to
During fingerprint recognition, correspondence fingerprint identification area 102a display brightness is higher than remaining region 102b display brightness, and this is over time
Increase, life time decay degree and corresponding remaining region 102b of correspondence fingerprint identification area 102a OLED longevity can be caused
Order attenuation degree and produce difference, so as to cause fingerprint identification area 102a display effect and remaining region 102b display effect not
Unanimously, so influence visual effect.
Therefore, the embodiments of the invention provide a kind of display methods of display module, including：
In fingerprint recognition, display brightness is gradually reduced from fingerprint identification area 102a center to border；
In normal display, display brightness from the fingerprint identification area 102a center to border gradually increase.
So, can be to the life consumption difference that is produced in fingerprint recognition from fingerprint identification area 102a center to border
Compensating action is played, the compensating action can make fingerprint identification area 102a and remaining region 102b life time decay curve tend to one
Cause, so as to so that fingerprint identification area 102a and remaining region 102b display effect reach unanimity, and then vision can be improved
Effect.
It is preferred that, as shown in figure 5, in fingerprint recognition, the display of many sub-regions (the 0th subregion~the 5th subregion)
Brightness is linearly successively decreased from fingerprint identification area 102a center to border.For example, near fingerprint identification area 102a center
The display brightness of subregion (the 0th subregion) is 500nits, and many sub-regions (the 0th subregion~the 5th subregion) is aobvious
Show that brightness is successively decreased 25nits successively from fingerprint identification area 102a center to border.Specifically, the display brightness of the 1st subregion is
475nits；The display brightness of 2nd subregion is 450nits；The display brightness of 3rd subregion is 425nits；4th subregion
Display brightness is 400nits；The display brightness of 5th subregion is 475nits.
In fingerprint recognition, remaining region 102b display brightness is 0.
It is preferred that, as shown in fig. 6, in normal display, the display of many sub-regions (the 0th subregion~the 5th subregion)
Brightness is linearly incremented by from fingerprint identification area 102a center to border.
It is further preferred that in normal display, near subregion (the 5th sub-district on fingerprint identification area 102a border
Domain) the reduced value of display brightness of the display brightness relative to remaining region 102b be less than or equal to the aobvious of remaining region 102b
Show the 0.8% of brightness.So, it can make near the subregion on fingerprint identification area 102a border and showing for remaining region 102b
Showing the difference of brightness will not be detected by human eye, so as to ensure visual effect.
For example, in normal display, near the display of the subregion (the 0th subregion) at fingerprint identification area 102a center
Brightness is 333.2nits, and many sub-regions (the 0th subregion~the 5th subregion) display brightness from fingerprint identification area
102a center to border 2.8nits incremented by successively.In normal display, remaining region 102b display brightness is 350nits.
So, the display brightness of the 5th subregion is approximately equal to remaining region relative to the reduced value of remaining region 102b display brightness
The 0.8% of 102b display brightness.
It should be noted that in the present embodiment, fingerprint identification area 102b is included from fingerprint identification area 102b center extremely
6 sub-regions that border is divided successively, but the invention is not limited in this, in actual applications, the quantity of subregion according to
It is specific to need to be also less than 6 or for more than 7.
It should also be noted that, in actual applications, in fingerprint recognition, display brightness is from fingerprint identification area 102a
The heart to border, which is gradually reduced, to be not limited to linearly successively decrease, and can also be successively decreased using other any regulars.In normal display, show
Show that brightness gradually increases from center to the border of the fingerprint identification area 102a to be not limited to linearly successively decrease, it can also be used
He successively decreases at any regular.As long as it is above-mentioned successively decrease or be incremented by rule disclosure satisfy that in fingerprint recognition from fingerprint identification area 102a's
The life consumption difference that center to border is produced plays compensating action.
As another technical scheme, the embodiment of the present invention also provides a kind of display methods of display device, and it includes this
The display methods for the above-mentioned display module that inventive embodiments are provided.
Above-mentioned display device can be flexible OLED display.
The display methods of display device provided in an embodiment of the present invention, it is by using provided in an embodiment of the present invention above-mentioned
The preparation method of display module, can make fingerprint identification area and the display effect of remaining viewing area reach unanimity, and then can change
Kind visual effect.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, but the invention is not limited in this.For those skilled in the art, the essence of the present invention is not being departed from
In the case of refreshing and essence, various changes and modifications can be made therein, and these variations and modifications are also considered as protection scope of the present invention.
