Cost is relatively low, it is easy to accomplish.
Detailed description of the invention
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In all the appended drawings, similar element
Or part is generally identified by similar appended drawing reference.In attached drawing, each element or part might not be drawn according to actual ratio.
Fig. 1 is the schematic diagram of the colored segment encode liquid crystal display of the present invention；
Fig. 2 is the schematic cross-section of the colored segment encode liquid crystal display of the present invention.
Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
The colored segment encode liquid crystal display 100 of Fig. 1 offer is be provided.Including segment display 10, driving IC20, RGB back
Light source 30 and backlight driver 40.Driving IC20 is used to control the opening timing of segment display 10, this is segment encode liquid crystal
The conventional arrangement of display.The application is changed the backlight of segment display 10 at RGB backlight 30 by single light source.Backlight
Driver 40 controls the lighting timings of RGB backlight 30 based on the opening timing of driving IC20, in the closing of segment display 10-
During opening-closing, RBG backlight 30 is controlled with colorful light-emitting, is made such that 10 display color of segment display
It is colored.
Specifically, referring to fig. 2, segment display 10 includes the upper polaroid 11 stacked gradually, upper substrate 12, COM conducting
Layer 13, COM oriented layer 14, space powder 151 and liquid crystal layer 152, SEG oriented layer 16, SEG conductting layer 17, lower substrate 18 and it is lower partially
Mating plate 19.Upper substrate 12 and lower substrate 18 are for providing segment display 10 structural support, upper polaroid 11 and down polaroid 19
For providing liquid crystal display necessary polarised light.COM conductting layer 13 provides unified public electrode, cooperation SEG conductting layer 17
Different voltages form voltage difference different between COM oriented layer 14 and SEG oriented layer 16.The voltage difference corresponds to liquid crystal layer 152
The different deflection angles of middle liquid crystal molecule, realize different luminous flux controls.
It shines because segment display 10 is not full frame, liquid crystal layer 152 needs adapted space powder 151, to separate out
The isolated area of multiple liquid crystal layers 152 is to form character or pen section.Correspondingly, SEG oriented layer 16 also includes that at least one is only
Vertical display unit 161, each independent display unit 161 correspond to an above-mentioned character or pen section.When IC20 being driven to be based on opening
Sequence successively controls each independent display unit 161 and successively opens.
Matched, RGB backlight 30 includes R, G, B tri- sub- backlights 31.Three sub- backlights 31 corresponding one
A independent display unit 161 simultaneously provides backlight.40 1 secondary control of backlight driver, one sub- backlight 31 shines.Cooperate each
The opening timing of independent display unit 161, backlight driver 40 control the independent display unit 161 in closing-opening-closing
During, a sub- backlight 31 of secondary control one shines.Cooperate refreshing frequency, in user's eye, the independent display unit 161
The color of sending, the as color of the sub- backlight 31.As the selection of 40 pairs of backlight driver sub- backlights 31 is different, this
Apply for that colored segment display 100 can at least be shone with three kinds of different backlight colors.
Further, the transformation of sub- backlight 31 can also be added in backlight driver 40 in the lighting timings of its control.
For example, backlight driver 40 controls the sub- backlight of R and B when being applied colored segment display 100 and needing to show purple
Backlight alternately shines.Thus cooperation refreshing frequency can make user observe purple.Further, backlight driver 40
The brightness of the sub- backlight of R, and the brightness of the adjustment sub- backlight of B can also be adjusted by controlling the drift angle of liquid crystal molecule, made
It obtains and occurs luminance difference therebetween, thus render partially red purple or partially blue purple.
Similar principle, backlight driver 40 are controlled by different lighting timings, and any two groups of sons can be made to carry on the back
Light source 31 alternately shines or any three groups of sub- backlights 31 alternately shine, so that the application colour segment display 100 is realized
Colour display.Further, different by the brightness of different sub- backlights 31, realize the further rendering to color.
It should be mentioned that the various colors that the application colour segment display 100 issues, not tri- dice backlight of RGB
The true color that source 31 renders after shining simultaneously, but pass through the difference of refreshing frequency and eye recognition frequency, to pass through difference
Color alternately shines and the different colours display effect of formation.Monochromatic display mode compared with the existing technology, the application are colored
Segment display 100 makes segment display that the colored function of showing may be implemented, and structure is simple, and cost is relatively low, is easy to real
It is existing.
Another embodiment, backlight driver 40 can control three sub- backlights 31 simultaneously while shine.Cooperation is each
The opening timing of a independent display unit 161, backlight driver 40 control the independent display unit 161 and close-are beating on-off
During closing, three sub- backlights 31 shine simultaneously.Backlight driver 40 is controlled by different lighting timings, can be made
Any one, two or three sub- backlights 31 shine so that the application colour segment display 100 open when
Colored display is directly presented.Further, different by the brightness of different sub- backlights 31, backlight driver 40 is also realized to color
Color further rendering.
In order to realize the frequency and effect of colorful light-emitting, allow refresh interval lower than 5 milliseconds, reaching naked eyes can not differentiate
Degree, it is also necessary to the overall thickness for controlling space powder 151 and liquid crystal layer 152 is less than 3um.Liquid in space powder 151 and liquid crystal layer 152
Brilliant viscosity was less than 30 millipascal seconds.Further, the duty ratio for driving IC20 is 1/1Duty, and the driving frequency of IC20 is driven to be greater than
50Hz。
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
