Description
Technical field
The present invention relates to intelligent hardware devices fields, are a kind of signal conversion systems of ink screen mobile phone more specifically.
Background technique
Electric ink is a kind of completely new information display new method and technology, as most conventional inks screens, Ke Yixian
Show above many different media, such as curved plastics, polymer PET, paper to cloth etc. is distinguished different from traditional paper, electricity
Sub- Heisui River screen can only show the image of variation when being powered, when no power be the printed words that will not be changed, and show and
Image will not disappear, and principle is to adhere to many volume very littles " microcapsules " on the surface of the material, encapsulate with the black of negative electricity
Color electron ion and white electron ion with positive electricity make the electron ion ordered arrangement of different colours by changing charge, to be in
Reveal in white and black effect of visualization.Existing electronic ink screen mobile phone products mainly use chip, such as high pass chip,
Need to add additional screen signal switching hardware light ink screen, at high cost, system flexibility is inadequate.
Summary of the invention
For disadvantages mentioned above, the signal transfer problem of purpose of the present invention chip input is real by following technical solution
Existing.
A kind of signal conversion system of ink screen mobile phone, processor module, ink panel module including circuit connection, processing
The DSI signal that device module is generated by built-in MIPI interface receives DSI signal by SPI interface and exports DPI signal and figure
Information, ink panel module receive DPI signal and graphical information, are shown as black and white gray number it is believed that breath.
Preferably, ink panel module also includes refresh module, periodically sends refreshing instruction to ink screen, and ink screen reception refers to
It enables and screen is refreshed.
Preferably, the ink screen is 18 or 24 RGB screens.
Preferably, the MIPI interface built in processor module is MIPI 2LANE output interface.
So that ink screen is worked the beneficial effects of the present invention are: not needing additional switching hardware, is realized by software approach
Signal conversion, reduces costs.
Detailed description of the invention
Fig. 1 is system structure diagram in the embodiment of the present invention.
Fig. 2 is cpu circuit structural schematic diagram in the embodiment of the present invention.
Fig. 3 is the structural schematic diagram of Lian Fake chip in the embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention.
As shown in Figure 1, a kind of signal conversion system of ink screen mobile phone, processor module, ink including circuit connection
Panel module, the DSI signal that processor module is generated by built-in MIPI interface are received DSI signal by SPI interface and are exported
DPI signal and graphical information, ink panel module receive DPI signal and graphical information, are shown as black and white gray number it is believed that breath.Ink
Panel module also includes refresh module, periodically sends refreshing instruction to display module, display module receives instruction, and carries out to screen
Refresh.
As shown in Fig. 2, Fig. 2 is processor module i.e. cpu circuit figure, it is to turn DSI signal referring to B4, C4 foot of circuit
Change output DPI signal, H (HSYNC) is line synchronising signal；V (VSYNC) is field sync signal, and simulated television uses electronics like that
Rifle carries out frequency sweep like that and shows, pixel is carried out Fast Filling, is finally displayed in ink screen.CPU others pin with
And circuit is not protection point of the invention, is not further described.
Referring to Fig. 3, specific embodiments of the present invention are illustrated by taking MTK (Lian Fake) chip as an example.MTK chip uses
MT6763-SBS, the screen interface that chip uses is MIPI 2LANE output, and ink screen is all 18 or 24 RGB screens,
Data after power-off in ink screen can lose, but ink screen mobile phone uses Android system, and the figure of the Android system of standard output
As being all full-color RGB data, black and white luma data can not be exported, so we need to utilize the original SPI interface of MTK chip
Black and white gray scale data signal is exported, electronic ink screen is worked normally.Specifically, in input terminal, A03, AE4 of chip, AD4,
Tetra- pins of AE3 connect input SPI signal with interface SPI_CSB, SPI_CLK, SPI_MO, SPI_MI respectively, in output end,
DPI_D0~DPI_D11 is output end, connects other circuits of e-book, is to export after converting signal from above-mentioned port,
DPI_HSYNC and DPI_VSYNC passes through the ink screen circuit connection of pin W26, W25 and ink panel module, is that will show data
Pixel is filled in display screen after conversion, realizes the effect of display pattern.
In an embodiment of the present invention, the DSI signal that MTK chip is generated by built-in MIPI interface, is driven by software
It is dynamic to close and changed into SPI interface, DPI signal and graphical information are issued, MIPI interface is first closed, then addition display
Device, then issue DPI signal and graphical information is shown to display, the code for closing MIPI interface addition display is as follows:
Above-mentioned function can be realized by above-mentioned software code, to achieve the purpose that signal is converted.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
