Block 123 produces the timing control signal for driving TFT display screen.
Timing control signal generation module 123, timing control signal generation module 123 is used for producing driving TFT display screen
（TFT display screen）Necessary timing control signal.Taking the TFT display screen of digital screen rgb interface type as a example, this functional module
Then need to produce VSYNC（Vertical synchronizing signal）、HSYNC（Horizontal-drive signal）, DE (data valid signal), PCLK（Pixel
Clock signal）Etc. necessary timing control signal.
Look-up table means 121 include the mapping relations of the first signal and secondary signal, when data processing module 12 receives the
After one signal, the first signal is converted to secondary signal by look-up table means 121, and timing control signal generation module 123 produces and drives
Timing control signal needed for dynamic TFT display screen；That is to say, look-up table means 121 include reflecting of the first signal and secondary signal
Penetrate relation, after data processing module 12 receives the first signal, the first signal is converted to secondary signal by data processing module 12.
Specifically, secondary signal is RGB tristimulus signals, is used directly for the display of TFT display screen.
Generally, the data structure of secondary signal is RGB565 (16bit), RGB666 (18bit) or RGB888 (24bit).
When carrying out image display, secondary signal, is also RGB tristimulus signals, controls R sub-pixel, G sub-pixel in TFT display screen
Show with B sub-pixel, and then realize TFT display screen display image.
Specifically, the first signal is usually the data of 1bit, and such as, data 1 represents black, and data 0 represents white, with
As a example the secondary signal of RGB888 (24bit), and taking the TFT display screen of normally black mode as a example, the secondary signal of black and white
The corresponding value of the secondary signal of color is respectively 00,000,000 00,000,000 00000000 and 11,111,111 11111111
11111111, in wherein 24 every eight bit data be followed successively by R sub-pixel, G sub-pixel and B sub-pixel signal.
Specifically, taking the secondary signal of 24 as a example, and taking the TFT display screen of normally black mode as a example：First signal with
The mapping relations of secondary signal such as following table 1- table 5：

Words frame）.
Embodiment two
This enforcement two is no longer repeated with embodiment one identical part, and this enforcement two is with the difference of embodiment one：Ginseng
Examine Fig. 1 b, Fig. 1 b is illustrated that the data processing module structural representation of another embodiment of the present invention；With reference to Fig. 1 b, at data
Reason module 12 includes：Look-up table means 121, interface adjusting module 122 and timing control signal generation module 123, its median surface
Adjusting module 122 is connected to look-up table means 121.
Interface adjusting module 122, for adjusting brightness and/or color during TFT display screen display secondary signal, be also
Adjust the mapping relations of the first signal and secondary signal.Interface adjusting module 15 is generally and the touch controlled key of peripheral hardware or physical button
It is connected Deng button, brightness when secondary signal shows in TFT display screen is adjusted by the touch potential that receive user triggers
And/or color；That is to say, when user presses the button of peripheral hardware, interface adjusting module 122 receives triggering touch potential, and according to
Triggering touch potential selects the mapping relations of corresponding first signal and secondary signal.
Taking the secondary signal of 24 data as a example, and taking the TFT display screen of normally black mode as a example：Tune in touch potential
Under whole, the first signal is as follows with the mapping relations of secondary signal：
Table 6
Table 6 is the look-up table of another kind of mapping relations of reflection the first signal and secondary signal.Reference table 6, first in table 6
Signal 0 and 1 maps the secondary signal data structure of 24 of 5 kinds of different key number of times respectively, each data structure corresponding
Plant Show Color, and the mapping relations that different touch potential correspondences is different.Interface adjusting module 122 passes through what reception triggered
Touch potential, is adjusted between five kinds of different mapping relations, thus adjusting the first signal to form secondary signal, and then adjusts
The color when showing for TFT display screen for the whole secondary signal.Wherein, touch potential 0 represents interface adjusting module 122 and does not adjust
The first signal when whole and the mapping relations of secondary signal, that is to say, interface adjusting module 122 does not receive triggering touch potential
When the state that shows of TFT display screen.More specifically, the first signal maps the display of the TFT display screen of 5 kinds of different touch potentials
State, wherein 0 to 4 touch potential corresponds to a kind of mapping relations respectively, and the touch potential according to triggering selects corresponding mapping
Relation；And when touch potential is more than 4 times, return the mapping relations of acquiescence（Acquiescence mapping relations be, touch potential
For mapping relations when 0）, also it is the mapping relations of the first signal when not adjusting and secondary signal.
Specifically, such as, when not triggering button, when that is, touch potential is equal to 0, for data 1, then latter 24 are changed
Secondary signal is 00,000,000 00,000,000 00000000, is shown as black after that is to say conversion in TFT display screen 13；Right
In data 0, then the secondary signal changing latter 24 is 11,111,111 11,111,111 11111111, that is to say after conversion in TFT
Be shown as white in display screen 13, wherein, display interface include background color show, the display of font or figure, it maps accordingly
Relation is all in accordance with table 6.
In this example, the adjustment to mapping relations for the interface adjusting module 122, can be corresponding by control button selection of times
Mapping relations；Those skilled in the art can relative set touch potential according to the actual requirements, the present embodiment do not limit to this.
Embodiment one and the display device of embodiment two offer, data processing module receives the first signal generator module and produces
The first signal, and the first signal is converted to secondary signal；And then TFT display screen receives secondary signal, and according to the second letter
Number shown.Therefore, the first signal is converted to the second letter using data processing module by the display device that the present embodiment provides
Number so that originally can only be in monochrome display devices（Monochrome display devices include single color display screen, such as MONO display screen）Display
First signal, the secondary signal being formed after data processing module conversion enables to be shown in TFT display screen, and then
Cross coupled between monochrome display devices and color display apparatus for first signal generator module is used, and TFT
The effect that display screen shows is more preferable than single color display screen.And in embodiment two, user also can pass through according to personal selection
Interface adjusting module selects corresponding mapping relations, and then selects corresponding conversioning colour and/or brightness, improves display device
Motility.
TFT display screen, can be for LCD（Liquid crystal display）TFT display screen, be alternatively be used for OLED（Organic light emission
Display）TFT display screen or TFT display screen can be additionally used in Electronic Paper etc., the embodiment of the present invention does not limit to this, when
TFT display screen is used for LCD（Liquid crystal display）When, this liquid crystal display can be FFS type or IPS type, and the embodiment of the present invention is not right
This limits.Data processing module 12 sends the secondary signal after changing to TFT display screen, and then enters in TFT display screen
Row display.
