Description
Technical field
The present embodiments relate to communication technical field, more particularly to a kind of display driver circuit, method and mobile terminal.
Background technology
At present, Rimless technology belongs to a kind of visual Rimless technology used by mobile terminal, by using
Light refraction principle, produce a kind of visual Rimless effect.But in existing application, due to the uniformity meeting of preparation technology
Cause mobile terminal display screen edge the problem of rainbow line occur, have impact on the display effect of mobile terminal.
For above-mentioned rainbow line problem, existing technology solution be by change the order of display screen display primary come
Solve.
Include multiple pixel cells for being used to show different base colors in the display screen of mobile terminal, according to display primary
Quantity is different, and the sub-pixel with required display primary respective amount is included in each pixel cell.For example, a pixel cell needs
Show red (R:Red), green (G：Green), indigo plant (B：Blue) during three kinds of primary colours, can specifically include successively in the pixel cell
Three sub-pixels of arrangement, for showing above-mentioned three kinds of primary colours respectively.
Certain order be present in the primary colours shown by sub-pixel in pixel cell.With pixel cell can show it is red, green,
Exemplified by blue three kinds of primary colours, as shown in figure 1, in the horizontal direction (i.e. on grid line direction), be arranged in order in pixel cell three
Sub-pixel is respectively used to show red, green, blue, then according to normal driving logic, three sub-pixels in the pixel cell from
Left-to-right is in illuminating state successively, so that the primary colours display order of the pixel cell is red, green, blue.
When display screen shows three kinds of primary colours successively by red, green, blue order, included data drive circuit in display screen
By the data wire being connected with sub-pixel, successively into picture element matrix positioned at the sub-pixel transmission data-driven letter of same pixel column
Number, to drive different subpixel to show three kinds of primary colours of red, green, blue successively by display order as shown in Figure 1.Under this state, such as Fig. 2
Shown, data drive circuit need not change output voltage, only need to keep output fixed potential example in a frame picture display time
Such as the data drive signal of positive and negative 5 volts (V).
So when solving the coloured silk that mobile terminal display screen occurs by changing the display order of primary colours in pixel cell
During rainbow line problem, due to the position and sub-pixel of the sub-pixel for showing different base colors, data wire and data drive circuit
Between annexation be it is fixed, therefore, can only be exported by the data drive signal of change data drive circuit logic come
Realize the change of primary colours display order.
By primary colours display order after change to illustrate exemplified by blue, red, green.Because the hardware of display screen can not change,
Therefore, for show the sub-pixels of red primaries be still arranged in the sub-pixel of display blue primary color before (i.e. grid line direction
Left side), data drive circuit is still first to the sub-pixel output data drive signal of display red primaries, then again to display
The sub-pixel output data drive signal of green primary and blue primary color, then in order to realize that it is suitable that blue, red, green primary colours are shown
Sequence, data drive circuit need first to export the data drive signal of zero V current potentials to the sub-pixel of display red primaries and green primary,
So that above-mentioned two sub-pixel is in not illuminating state, the data that 5V current potentials are then exported to the sub-pixel of display blue primary color are driven
Dynamic signal, so that the sub-pixel of display blue primary color is in illuminating state so as to show blue primary color, and in next scanning week
The data drive signal of sub-pixel output -5V current potentials in phase to the sub-pixel of display red primaries and to green primary, so that
Above-mentioned two sub-pixel is in illuminating state so as to show red, green primary successively.Due to including multiple pixel lists in a pixel column
There is saltus step in member, therefore, the current potential amplitude of data drive circuit output data drive signal, specifically can be as shown in Figure 3.
Due to the voltage magnitude saltus step of data drive circuit output data drive signal can cause display screen power consumption significantly on
Rise, so as to accelerate the electric quantity consumption of mobile terminal, reduce the standby and usage time of mobile terminal.
The content of the invention

The data wire that the sub-pixels 42 of primary colours connects is connected, then again respectively with the sub-pixel for showing red primaries, green primary
The data wires of 42 connections are connected, blue, red, green to realize so as to the order of lighting by controlling sub-pixel 42 in pixel cell 41
Three kinds of primary colours are shown according to specified order.The primary colours display sequence control of other pixel cells of second pixel column is identical.
When the grid line that the 3rd pixel column is connected is in open mode, data drive circuit equally exports fixed potential
Data drive signal.Data distributor 44 receives the data drive signal, and the SECO generated according to time schedule controller 43
Signal, first with for showing data wire connection that the sub-pixel 42 of green primary is connected, then again respectively with for showing blueness
The data wire that primary colours, the sub-pixel 42 of red primaries connect is connected, and realizes green, blue, red primary colours display order.
The primary colours display sequence control of follow-up other pixel columns the like, repeat no more.
The adjustment and control of primary colours display order in mobile terminal display screen can be achieved in operation more than, so as to aobvious
Writing reduces the power consumption of mobile terminal display screen, reduces the electric quantity consumption of mobile terminal, when increasing the standby of mobile terminal and using
Between.By comparative analysis, technical scheme can reduce by 50% power consumption compared to prior art.
Meanwhile the technical scheme that the embodiment of the present invention is provided is by making the display primary of pixel cell 41 in different pixels row
The change of order, such as the color for showing adjacent subpixels 42 are different, so as to be effectively improved rainbow present in prior art
Line problem, it is ensured that the display effect of mobile terminal.
Technical solution of the present invention is said so that pixel cell 41 includes three sub-pixels 42 as an example in above-described embodiment
It is bright, but four or other numbers can also be included in other embodiments, in the pixel cell 41 involved by the embodiment of the present invention

The structural representation of distributor 44, and in the another specific embodiment of the present invention, as shown in fig. 6, the embodiment of the present invention is provided
Display driver circuit 40 may be provided with multiple data distributors 44.
Moreover, when data distributor 44 has multiple, the data wire of a connection of data distributor 44 is same with belonging to
The sub-pixel 42 of individual pixel cell 41 connects.In i.e. multiple data distributors 44, a data distributor 44 is responsible for data row side
The control of upward at least one primary colours display order of pixel cell 41.So as to reduce the live load of data distributor 44, really
Protect reliability, the accuracy of the adjustment of primary colours display order and control.
Time schedule controller 43 involved by the embodiment of the present invention specifically may be disposed in data drive circuit, may also set up in
In display screen, it can also be arranged in mobile terminal.The time schedule controller 43 concretely circuit structure or logic chip, at that time
When sequence controller 43 is circuit structure, the circuit can be specifically made up of electronic devices such as transistors, when time schedule controller 43 is to patrol
When collecting chip, the logic chip can be to have ripe Programmable logical controller chip, such as 74 family chips.It can be seen that this hair
