Embodiment
Embodiments provide a kind of display control method, display control unit and display, while improving user's experience of display, the power consumption of display can be saved.Below with reference to accompanying drawing, by specific embodiment, the present invention is further illustrated.
Please refer to Fig. 1, the display control method described in the embodiment of the present invention, be applied to a display, comprise the following steps:
Step 11, with the first refresh rate F1 preset, refreshes and shows the first image corresponding to frame data;
Step 12, is adjusted to the second refresh rate F2 by the refresh rate of display by F1, and is kept by described first image, wherein F2 < F1.
In the present embodiment, display is when the image that the every frame data of display are corresponding, by performing above-mentioned steps 11 ~ 12, thus refresh with the first refresh rate F1 and show image corresponding to these frame data, then, the refresh rate of display is reduced to F2 from F1, to save the power consumption of driving circuit, and image corresponding for these frame data is kept, until display next frame data.
As can be seen from the above, image display work of the prior art divide into and refreshes and keep two stages by the present embodiment, obtain image in the refreshing stage with higher refresh rate and show, thus the time generated needed for picture can be reduced, reduce visual shake sense, improve the stimulation of picture refreshing to human eye, improve user's experience; And in the maintenance stage, then turn down the refreshing frequency of display, reduce the power consumption of driving circuit, and image is kept one period of schedule time, can equipment power dissipation be saved thus.According to the experiment of inventor, after finding to adopt method described in the present embodiment, the average power consumption of display have dropped 100 ~ 200mW.
In above step 12, to refresh and the first image showing frame data corresponding comprises: generate the first picture signal that described frame data are corresponding, and with described first refresh rate F1, described first picture signal is refreshed the pixel to described display.
In above step 12, described first image is kept comprising: described first image was kept for first schedule time, and wherein, within described first schedule time, the refresh rate of described display is described second refresh rate F2.Here, described first schedule time is 1/F2-1/F1.For improving user's experience, preferably, described first refresh rate F1 is the maximum refresh rate that described display is supported, to obtaining best visual experience effect.
When described first schedule time expires, namely when described first image maintained for first schedule time, now the refresh rate of described display is adjusted to the first refresh rate F1 by the second refresh rate F2 by the present embodiment, and with described first refresh rate F1, refresh and show the second image corresponding to next frame data.
Please refer to Fig. 2, by contrasting with the display effect of prior art, further illustrating the advantage of the present embodiment:
In Fig. 2, the letter in each square represents corresponding image, and the square representative of filling shade refreshes display image, and the square representative of not filling shade keeps image.Due to prior art employing is the mode of operation at the uniform velocity refreshed, and therefore, when refresh rate is 60Hz and 30Hz, the time of refreshing piece image is 1/60 second and 1/30 second respectively.When refresh rate is 30Hz, it is longer that piece image refreshes the 1/30 second time generated, and may cause visual flicker, affect user's experience.Fig. 2 shows the display effect (F1=60Hz after application the present embodiment, F2=30Hz), the time of refreshing generation piece image adopts the time during refresh rate of 60Hz identical with prior art, after image refreshing, the refresh rate of driving circuit reduces to 30Hz, this image is kept 1/60 second simultaneously, within this period of retention time, driving circuit does not carry out refreshing and the display of next frame data immediately, but stop circuit of display driving work, until the schedule time expires carry out refreshing display with the refresh rate of 60Hz to next frame data again, thus its power consumption is reduced, therefore, it is possible to reach the object of saving equipment energy consumption.
The present embodiment is with described first refresh rate F1, to refresh and after showing the second image corresponding to next frame data, further the refresh rate of described display can be adjusted to the 3rd refresh rate F3 by the first refresh rate F1, and described second image was kept for second schedule time, described second schedule time is 1/F3-1/F1, wherein F3 < F1.Here, F3 can be equal with F2, also can not wait.
That is, after adopting method described in the present embodiment, display can refresh with a higher refresh rate F1 (can be the highest refresh rate that this display is supported) and show image, to reduce the time generated needed for picture, reduces visual shake and feels; Meanwhile, image can also be kept the schedule time with lower refresh rate, to save power consumption by the present embodiment.And; because the present embodiment can by the length of retention time; realize maintenance stage different refresh rate; like this; the present embodiment is when user adjusts active accommodation display refresh rate; then can not there is blank screen or the abnormal phenomenon of screen display of the generation when refresh rate switches in prior art; such as prior art is when refresh rate is adjusted to 30Hz from 60Hz by user; because driving circuit needs to reset; display there will be blank screen phenomenon as shown in Figure 3 usually; cause display normally not show, have a strong impact on user's experience.The present embodiment can avoid this phenomenon by following steps, and now, the display control method described in the present embodiment, after above-mentioned steps 12, can also comprise:
Step 13, receives the refresh rate adjusted value F4 of user's input;
Step 14, when described first schedule time expires, with the first refresh rate F1 preset, refreshes and shows the 3rd image corresponding to next frame data;
Step 15, is adjusted to described refresh rate adjusted value F4 by the refresh rate of described display by F1, and described 3rd image was kept for the 3rd schedule time, and described 3rd schedule time is 1/F4-1/F1, wherein F4 < F1.
Like this, the present embodiment is when arranging according to user the refresh rate adjusting display, refresh rate user inputted is as the refresh rate keeping the stage, and determine the retention time accordingly, as can be seen from the refresh rate adjustment schematic diagram that Fig. 3 provides, due to only by adjusting the time in maintenance stage, the adjustment of refresh rate need can be realized in the present embodiment, therefore there will not be blank screen of the prior art or the abnormal phenomenon of screen display, thus significantly improve the experience of user.
The embodiment of the present invention additionally provides a kind of display control unit, is applied to a display, and as shown in Figure 4, this device comprises:
Refresh unit, for the first refresh rate F1 preset, refreshes and shows the first image corresponding to frame data;
Holding unit, for the refresh rate of display is adjusted to the second refresh rate F2 by F1, and keeps described first image, wherein F2 < F1.
Concrete, described holding unit comprises:
First processing unit, for described first image is kept the schedule time, wherein, within the described schedule time, the refresh rate of described display is described second refresh rate F2.Here, preferably, the described schedule time is 1/F2-1/F1.
Concrete, described refresh unit comprises:
Second processing unit, for generating the first picture signal corresponding to described frame data, and with described first refresh rate F1, refreshes the pixel to described display by described first picture signal.Here, preferably, described first refresh rate is the maximum refresh rate that described display is supported.
