It is flat ", " vertical " etc., be only the direction for referring to annexed drawings.Therefore, the direction term used is to illustrate and understand this hair
It is bright, and it is not used to the limitation present invention.
Fig. 2 and Fig. 3 are referred to, Fig. 2 is the schematic diagram of flexible displays 100 of the present invention, and Fig. 3 is flexible displays of the present invention
100 profile.The flexible displays 100 of the present invention include liquid crystal display panel 106 and backlight module 108.LCD
Plate 106 includes thin film transistor base plate 120, colored optical filtering substrates 122 and liquid crystal layer 126.Liquid crystal layer 126 is located at thin film transistor (TFT)
Between substrate 120 and colored optical filtering substrates 122.Colored optical filtering substrates 122 include black-matrix layer 125 and colored film layer 126.
Liquid crystal display panel 106 is by colored film layer 126, to isolate the light of red green blue tricolor, to show chromatic image.It is black
Color matrix layer 125 is used for avoiding light leak.Thin film transistor base plate 120 includes several data wires 102, several sums of scan line 104
Individual pixel cell 110.Each pixel cell 110 is electrically connected at a data wire 102 and scan line 104.Backlight module 108 is wrapped
Containing substrate 111 and multiple backlights 112, multiple backlights 112 are placed on substrate 111.Multiple backlights 112 can be luminous
Diode light-source, organic light-emitting diode light source or quantum dot.Liquid crystal display panel 106 and backlight module 108 are all in bending
Shape.
The type of drive of liquid crystal display panel 106 is as described below:The scanning signal that gate drivers 22 are exported passes through scanning
Line 104 is inputted so that the pixel cell 110 of connection scan line 104 receives the data-signal that source electrode driver 24 is exported, and makes pixel
Unit 110 is charged to required voltage.The liquid crystal of the top of pixel cell 110 is exactly to reverse (twist) according to the data-signal, is entered
And show different GTGs.Gate drivers 22 can export scanning signal line by line by several scan lines 104, then
Discharge and recharge is carried out by 22 pairs of pixel cells 110 per a line of source electrode driver.So sequentially go down, just can complete LCD
The complete display of plate 106.
Referring to Fig. 4, Fig. 4 is the signal of the backlight module 108 and liquid crystal display panel 106 of first embodiment of the invention
Figure.Liquid crystal display panel 106 includes the first viewing area 151 and the second viewing area 152.In the present embodiment, the first viewing area
151 curvature is more than the curvature of the second viewing area 152.For purposes of illustration only, the first viewing area 151 is located at liquid crystal display panel 110
The maximum region of angle of bend, and the first viewing area 151 is generally in ellipse.Because the curvature of the first viewing area 151 is more than
The curvature of second viewing area 152, so under the same distribution density of backlight 112, the display brightness meeting of the first viewing area 151
Less than the second viewing area 152.Therefore the present embodiment by the distribution density of multiple backlights 112 with the brightness of corresponding viewing area
And adjust so that the distribution density corresponding to multiple backlights 112 of the first viewing area 151 is more than corresponding to the second viewing area
The distribution density of 152 multiple backlights 112.
Because the distribution density corresponding to multiple backlights 112 of the first viewing area 151 is more than corresponding to the second viewing area
The distribution density of 152 multiple backlights 112, so the first viewing area 151 can obtain higher brightness.In display, the
One viewing area 151 can be consistent with the adjustment of the display brightness of the second viewing area 152, with improve the first viewing area 151 because curvature compared with
Cause the phenomenon of dark space greatly.
Referring to Fig. 5, Fig. 5 is the signal of the backlight module 108 and liquid crystal display panel 106 of second embodiment of the invention
Figure.Liquid crystal display panel 106 includes middle viewing area 170, the first viewing area 171 and the second viewing area 172.In the present embodiment
In, middle viewing area 170 is located at the centre of liquid crystal display panel 106, and the first viewing area 171 is located at middle viewing area 170 and the
Between two viewing areas 172, specifically, the second viewing area 172 is to be located at the both-side ends of liquid crystal display panel 106.First display
Area 171 is generally in ellipse.Because the angle of bend of liquid crystal display panel 106 is increased from center to both sides, therefore same
The distribution density of backlight 112 under, the display brightness of liquid crystal display panel 106 is reduced from center toward both sides.The present embodiment will be many
The distribution density of individual backlight 112 is adjusted with the brightness of corresponding viewing area so that corresponding to many of the first viewing area 171
The distribution density of individual backlight 112 is less than the distribution density for the multiple backlights 112 for corresponding to middle viewing area 170, more than pair
Should be in the distribution density of multiple backlights 112 of the second viewing area 172.That is, the distribution density of multiple backlights 112
It is as liquid crystal display panel 106 is reduced from center toward both sides.
Because the distribution density of multiple backlights 112 is also as liquid crystal display panel 106 is reduced from center toward both sides, institute
Higher brightness can be obtained with the second viewing area 172, the first viewing area 171 is taken second place, middle viewing area 170 obtains relatively low bright
Degree.In display, the display brightness adjustment of middle viewing area 170, the first viewing area 171 and the second viewing area 172 is consistent, to change
Kind first viewing area 151 causes the phenomenon of the generation of liquid crystal display panel 106 dark space because of curvature difference.
Compared to prior art, the present invention is close by the distribution of multiple backlights on the backlight module for flexible displays
Spend and adjusted with the curvature of liquid crystal display panel, flexible displays can be improved because thin film transistor base plate and colored optical filtering substrates are wrong
Position and form dark space, cause the technical problem of display picture brightness disproportionation.
In summary, although the present invention it is disclosed above with preferred embodiment, but the preferred embodiment and be not used to limitation
The present invention, one of ordinary skill in the field without departing from the spirit and scope of the present invention, can make various changes and profit
Adorn, therefore protection scope of the present invention is defined by the scope that claim is defined.
