Embodiment
The embodiment of the invention provides a kind of display control method, display control unit and display, can when improving user's experience of display, save the power consumption of display.Below with reference to accompanying drawing, the present invention is further illustrated by specific embodiment.
Please refer to Fig. 1, the described display control method of the embodiment of the invention is applied to a display, may further comprise the steps:
In the present embodiment, display is when showing image corresponding to every frame data, by carrying out above-mentioned steps 11～12, thereby refresh and show the image that these frame data are corresponding with the first refresh rate F1, then, the refresh rate of display is reduced to F2 from F1, to save the power consumption of driving circuit, and the image that these frame data are corresponding maintenance, until show the next frame data.
Can find out from the above, the present embodiment has been divided into image demonstration work of the prior art and refreshes and keep two stages, obtain image with higher refresh rate and show refreshing the stage, thereby can reduce the required time of picture that generates, reduce visual shake sense, improve picture refreshing to the stimulation of human eye, improve user's experience; And in the maintenance stage, then turn down the refreshing frequency of display, and reduce the power consumption of driving circuit, and image is kept one period schedule time, can save equipment power dissipation thus.According to inventor's experiment, find to adopt the described method of the present embodiment after, the average power consumption of the display 100～200mW that descended.
In the above step 12, refresh and show that the first image corresponding to frame data comprises: generate the first picture signal corresponding to described frame data, and with described the first refresh rate F1, described the first picture signal is refreshed pixel to described display.
In the above step 12, described the first image is kept comprising: described the first image was kept for first schedule time, and wherein, the refresh rate of described display is described the second refresh rate F2 within described first schedule time.Here, described first schedule time is 1/F2-1/F1.For improving user's experience, preferably, described the 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, be that described the first image is when keeping for first schedule time, this moment, the present embodiment was adjusted into the first refresh rate F1 with the refresh rate of described display by the second refresh rate F2, and with described the first refresh rate F1, refresh and show the second image that the next frame data are corresponding.
Please refer to Fig. 2, compare by the display effect with prior art, further specify the advantage of the present embodiment:
Among Fig. 2, the letter in each square represents corresponding image, and the square representative of filling shade refreshes the demonstration image, and the square representative of not filling shade keeps image.Because what prior art adopted is the mode of operation that at the uniform velocity refreshes, therefore, when refresh rate was 60Hz and 30Hz, the time of refreshing piece image was respectively 1/60 second and 1/30 second.When refresh rate was 30Hz, it is longer that piece image refreshes 1/30 second time of generation, may cause visual flicker, affects user's experience.Fig. 2 shows the display effect (F1=60Hz behind application the present embodiment, F2=30Hz), time when refreshing the refresh rate of time of generating piece image and prior art employing 60Hz is identical, after image refreshing is complete, the refresh rate of driving circuit is reduced to 30Hz, simultaneously this image was kept 1/60 second, this section in the retention time driving circuit do not carry out immediately refreshing of next frame data and show, but stop circuit of display driving work, until the refresh rate that the schedule time expires with 60Hz again refreshes demonstration to the next frame data, thereby so that its power consumption is reduced, therefore can reach the purpose of saving equipment energy consumption.
The present embodiment is with described the first refresh rate F1, after refreshing and showing the second image corresponding to next frame data, can be further the refresh rate of described display be adjusted into the 3rd refresh rate F3 by the first refresh rate F1, and described the second image kept for second schedule time, described second schedule time is 1/F3-1/F1, wherein F3＜F1.Here, F3 can equate with F2, also can not wait.
That is to say, after adopting the described method of the present embodiment, display can refresh and shows image with a higher refresh rate F1 (can be the highest refresh rate that this display is supported), generates the required time of picture to reduce, and reduces visual shake sense; Simultaneously, the present embodiment can also keep the schedule time with image with lower refresh rate, to save power consumption.And; because the present embodiment can be by the length of retention time; realize the refresh rate that the maintenance stage is different; like this; when the present embodiment is adjusted the active accommodation display refresh rate the user; the blank screen or the abnormal phenomenon of screen display that produce when refresh rate switches then can not occur in the prior art; for example prior art is when the user is adjusted into 30Hz with refresh rate from 60Hz; because driving circuit need to be reset; blank screen phenomenon as shown in Figure 3 can appear in display usually; cause display normally not show, have a strong impact on user's experience.The present embodiment can be avoided this phenomenon by following steps, and at this moment, the described display control method of the present embodiment can also comprise after above-mentioned steps 12:
Step 13 receives the refresh rate adjusted value F4 that the user inputs;
Step 14 when described first schedule time expires, with the first default refresh rate F1, refreshes and shows the 3rd image that the next frame data are corresponding;
Step 15 is adjusted into described refresh rate adjusted value F4 with the refresh rate of described display by F1, and described the 3rd image was kept for the 3rd schedule time, and described the 3rd schedule time is 1/F4-1/F1, wherein F4＜F1.
Like this, the present embodiment is when arranging to adjust the refresh rate of display according to the user, with the refresh rate of user input as the refresh rate that keeps the stage, and determine accordingly the retention time, can find out from the refresh rate adjustment schematic diagram that Fig. 3 provides, owing to only needing the time by the adjustment maintenance stage in the present embodiment, can realize the adjustment of refresh rate, therefore the abnormal phenomenon of blank screen of the prior art or screen display can not occur, thereby significantly improve user's experience.
The embodiment of the invention also provides a kind of display control unit, is applied to a display, and as shown in Figure 4, this device comprises:
Refresh unit is used for the first default refresh rate F1, refreshes and shows the first image that frame data are corresponding;
Holding unit is used for the refresh rate of display is adjusted into the second refresh rate F2 by F1, and described the first image is kept, wherein F2＜F1.
Concrete, described holding unit comprises:
The first processing unit is used for described the first image is kept the schedule time, and wherein, the refresh rate of described display is described the second refresh rate F2 within the described schedule time.Here, preferably, the described schedule time is 1/F2-1/F1.
Concrete, described refresh unit comprises:
The second processing unit is used for generating the first picture signal corresponding to described frame data, and with described the first refresh rate F1, and described the first picture signal is refreshed pixel to described display.Here, preferably, described the first refresh rate is the maximum refresh rate that described display is supported.
In the present embodiment, described device also comprises:
