Specific embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following retouches
State when being related to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.
Implementation method described in following exemplary embodiment does not represent all embodiment party consistent with the disclosure
Formula.Conversely, they be only with described in detail in such as appended claims, disclosure some in terms of phase one
The example of cause.
Figure 1A is refer to, it illustrates the knot of the display module 100 shown in one exemplary embodiment of the disclosure
Structure schematic diagram.The display module 100 includes：Crystal oscillator 110, spreading unit 120, display driver element 130
IC140 is driven with display.
Wherein, crystal oscillator 110 is the corresponding crystal oscillator of display driver element 130, and the crystal oscillator 110 can be display
The inside crystal oscillator of driver element 130, or the outer external crystal-controlled oscillation hung over outside display driver element 130.
Display driver element 130 is used to drive IC140 transmitting display datas to display, and accordingly, display is driven
Dynamic IC140 carries out the display of image, the display driver element 130 according to the display data control display screen for receiving
Can be GPU, CPU or MCU etc., the disclosure is not to crystal oscillator 110 and display driver element 130
Type be defined.
The operations such as the execute instruction of display driver element 130, transmission data, are built upon the generation of crystal oscillator 110
On the basis of frequency of oscillation, the frequency of oscillation that crystal oscillator 110 is produced is higher, and display driver element 130 is performed and referred to
Make, transmit the speed of data faster；The frequency of oscillation that crystal oscillator 110 is produced is lower, display driver element 130
Execute instruction, the speed of transmission data are slower.
And crystal oscillator 110 can produce radiation interference while frequency of oscillation is produced, and radiation interference intensity
Peak value can be reached near dominant frequency.Produced because the transmission of display driver element 130 data are built upon crystal oscillator 110
On the basis of raw frequency of oscillation, so when crystal oscillator 110 is operated near dominant frequency, display driver element 130
IC140 is driven to transmit data to display by transmission line, the radiation interference on transmission line can also reach peak value.
The radiation interference can produce influence to other components in electronic equipment, especially to electronic equipment radiofrequency signal
Interference is larger, such as, for the smart mobile phone of some high-resolution display screens of configuration, if not to passing
Radiation interference on defeated line is suppressed, and the signal of smart mobile phone will be affected.
In order to be solved from root when near dominant frequency, the interference of radiation on transmission line to radiofrequency signal is led to
Cross and crystal oscillator 110 is electrical connected with spreading unit 120, crystal oscillator 110 is opened up using spreading unit 120
Frequency is processed.
Wherein, spread-spectrum processing is to disturb crystal oscillator 110 in the spike of primary band to be converted into predetermined spread spectrum width
Interior wide-band interference, wherein, the peak strength of spread-spectrum processing previous peaks interference is more than wideband after spread-spectrum processing
The peak strength of section interference.By after spread-spectrum processing, the radiation interference that crystal oscillator 110 is produced near dominant frequency not
Spike aggregation again, but keep gentle in certain frequency width near dominant frequency, and in relatively low radiation interference
Strength level.
Due to being electrical connected between crystal oscillator 110 and display driver element 130, and display driver element 130 with
Display drive it is connected by transmission line 150 between IC140, crystal oscillator 110 by spreading unit 120 spread spectrum
After treatment, frequency of oscillation is produced so that display driver element 130 can be according to the frequency of oscillation, by passing
Defeated line 150 drives IC140 transmission data to display, wherein, the transmission line 150 can be MIPI transmission lines.
Display driver element 130 drives IC140 to send data according to the frequency of oscillation after treatment to display, i.e.,
The data transmitted on transmission line 150 have passed through spread-spectrum processing, the radiation interference that data are produced in transmitting procedure,
Also become in order to the wide-band in predetermined spread spectrum width is done by the spike interference before non-spread-spectrum processing in primary band
Disturb, the peak strength of radiation interference is greatly reduced, and stabilization is in reduced levels.
Schematically, before spread-spectrum processing and after spread-spectrum processing, radiation interference intensity and frequency on transmission line 150
As shown in Figure 1B, wherein X-axis represents frequency to relation between rate, and Y-axis represents the radiation interference on transmission line
Intensity.It will be apparent that before spread-spectrum processing, on transmission line near dominant frequency (i.e. 1000MHz in figure)
Radiation interference into needle pattern, and by after spread-spectrum processing, (i.e. spread spectrum is wide for certain frequency width near dominant frequency
Degree) in, the radiation interference intensity decreases on transmission line, and it is more steady.
By after spread-spectrum processing, 150 radiation interference intensity is reduced on transmission line, when the radiation is dry
It is cost-effective when disturbing intensity decreases to predetermined strength, you can save EMI protective layers on transmission line 150；And
And, due to by after spread-spectrum processing, the constant interval of radiation interference intensity reduces and certain near dominant frequency
Stabilization is kept in frequency range, the radio frequency unit in electronic equipment can enter to the radiation interference intensity of the stabilization
Row filtering, so as to further reduce the radiation interference on transmission line, improves the quality of radiofrequency signal, the disclosure
The follow-up optimization processing that radio frequency unit is carried out is not defined.
In sum, the display module that the present embodiment is provided, by increasing spreading unit in the electronic device,
And spread-spectrum processing is done to the corresponding crystal oscillator of display driver element by the spreading unit；Solve addition extra
EMI protective layers are, it is necessary to take larger space in electronic equipment body, and relatively costly problem；Reach
