The invention also discloses the control method based on above-mentioned display device, the setting instruction sent according to peripheral hardware determines most
The resolution ratio and refresh rate that whole display screen is shown, including manual setting pattern, automatic Setting pattern and intelligent set pattern, below
Each Setting pattern is described in detail respectively：
For manual setting pattern：As shown in figure 3, peripheral hardware sends the screen ginseng setting comprising resolution ratio and refresh rate setting value
Instruction, the resolution ratio and refresh rate that display device is shown using this resolution ratio and refresh rate as final display screen；Then according to this
Determining screen ginseng completes EDID conversions and receives the picture signal that peripheral hardware is sent, and the refresh rate according to setting modulates corresponding frequencies
Clock signal；Then received image signal is converted into the image data with the resolution match set, specific transfer process is：
If the resolution ratio of setting is less than display screen highest resolution, image is allowed to be shown centered on, surrounding insufficient section fills out black processing；If
The resolution ratio of setting is equal to display screen highest resolution, then allows image display all over the screen, and after being corrected processing to image data
It exports to display screen；Display screen is shown centered on the image data after correction under the control of clock signal.
For automatic Setting pattern：It is set comprising the screen ginseng that resolution ratio is preferential or refresh rate is preferential as shown in figure 4, peripheral hardware is sent
Set instruction, when resolution ratio is preferential, resolution ratio that final display screen is shown is determined as its intrinsic highest resolution, refresh rate by
Maximum processing capability determines the refresh rate upper limit, and when refresh rate is preferential, the refresh rate that final display screen is shown is its intrinsic refreshing
The upper limit of rate, resolution ratio are determined by maximum processing capability；Then EDID conversions are completed according to the screen ginseng determined therefrom that and receives peripheral hardware hair
The picture signal sent, the refresh rate according to setting modulate the clock signal of corresponding frequencies；Then received image signal is converted
At the image data of the resolution match with setting, specific transfer process is：When refresh rate is preferential, then the resolution ratio set is small
In display screen highest resolution, image is allowed to be shown centered on, surrounding insufficient section fills out black processing；When resolution ratio is preferential, then set
Resolution ratio be equal to display screen highest resolution, then allow image display all over the screen, and exported after being corrected processing to image data
To display screen；Display screen shows the image data after correction under the control of clock signal.
For intelligent set pattern：As shown in figure 5, peripheral hardware sends the screen ginseng setting instruction comprising display pattern setting, according to
Its corresponding resolution ratio and refresh rate are searched according to display pattern, this resolution ratio and refresh rate are shown as final display screen
Resolution ratio and refresh rate；Then join according to the screen determined therefrom that and complete the picture signal that EDID conversion reception peripheral hardwares are sent, foundation is set
Fixed refresh rate modulates the clock signal of corresponding frequencies；Then received image signal is converted into the resolution match with setting
Image data, and after being corrected processing to image data output to display screen；Display screen occupies under the control of clock signal
Image data after middle display correction.
The use process of the present invention is, as shown in Figure 1, when requiring to handle dynamic video image, to pass through hand
Dynamic setting, automatic setting or intelligent set pattern setting comparatively low resolution high refresh rate are joined as final screen, using crystal oscillator and
PLL generates high-frequency clock signal and display screen is made to reach maximum refresh rate, and vision signal is not enough to that display screen is completely covered
Place, fill out black processing；When requiring the video image not high to still image or rate of motion to handle, by manual
Setting, automatic setting or the low refresh rate of the opposite high-resolution of intelligent set pattern setting are joined as final screen, use crystal oscillator and PLL
Generating low-frequency clock signal makes display screen reach relatively low refresh rate, and vision signal is full of entire display screen, reaches maximum
Resolution ratio.
Requirement is presented in the different information that the present invention can be directed to dynamic/still image, and the resolution of display device is flexibly arranged
Rate and refresh rate, it is more flexible that image information is presented to receiver more well.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
