The embodiment of the invention discloses a kind of pixel call method, device and terminal, it is possible to reduce the rate of decay of screen pixels point.Describe in detail individually below.
Refer to the schematic flow sheet that Fig. 1, Fig. 1 are a kind of pixel call methods that the embodiment of the present invention provides.Concrete, the described method of the embodiment of the present invention can be applied particularly in above-mentioned terminal, the display screen of described terminal is made up of at least one screen pixels, each screen pixels includes red sub-pixel point, green sub-pixels point and blue subpixels point, as it is shown in figure 1, the described pixel call method of the embodiment of the present invention may comprise steps of:
101, obtain the target sub-pixel point in screen pixels and need the target gray scale value of display.
Wherein, described target sub-pixel point is red sub-pixel point (R) in described screen pixels, green sub-pixels point (G) or blue subpixels point (B).This target gray scale value is the grey decision-making that described screen pixels needs to need under the color shown and color of object to call the output of this target sub-pixel point.
It should be understood that, each sub-pixel point in this screen pixels can be an OLED, the OLED of this red sub-pixel point (R) correspondence is used for showing that the OLED of redness (glowing), green sub-pixels point (G) correspondence is used for showing green (green light), and the OLED that blue subpixels point (B) is corresponding is used for showing blueness (blue light-emitting).
102, judge that whether described target gray scale value is lower than preset gray scale threshold value.
Wherein, this preset gray scale threshold value can be specially a relatively low grey decision-making, and it can pre-set according to different subpixel point and obtain.That is, preset gray scale threshold value corresponding to different subpixel point can be identical, it is also possible to different, the embodiment of the present invention does not limit.Concrete, if judging to obtain this target gray scale value lower than this preset gray scale threshold value, then can perform step 103；Otherwise, then color can be carried out according to existing scheme by these three sub-pixels.
103, close the driving of described target sub-pixel point, and call in described screen pixels the sub-pixel point except described target sub-pixel point and carry out color and show.
In specific embodiment, can in screen pixels this target sub-pixel point composition less such as this target gray scale value lower than preset gray scale threshold value time, close the driving of this target sub-pixel point, and call other two the sub-pixels in screen pixels and carry out color and show, to reduce the lighting time of this target sub-pixel point.
For example, owing in OLED, blue emitting material and blue subpixels point are generally decayed the fastest, several times of red often and green luminescent material, thus can using the blue subpixels point in screen pixels as this target sub-pixel point.Thus can when in screen pixels, blue component is less, when grey decision-making such as blue subpixels point is relatively low, show that current screen pixel needs the color of display either directly through red sub-pixel point and green sub-pixels point, and close the driving of blue subpixels point, it is thus possible to reduce its loss by reducing the lighting time of blue subpixels point, slow down aging, extend its life-span, and do not affect again the display exporting color on display screen simultaneously.
It should be understood that, when showing, by red sub-pixel point and green sub-pixels point, the color that current screen pixel needs display, it can be the grey decision-making of directly output preparation output originally, or can also is that output carries out blue subpixels point and drives the grey decision-making readjusted after closing, the embodiment of the present invention does not limit.

208, the grey decision-making according to two sub-pixels in the described first pixel gray level value combination determined calls said two sub-pixel point to show described color of object.
In specific embodiment, can should be the GTG interval that the RGB grey decision-making that in this pixel gray level look-up table, this color of object is corresponding combines place with the Show Color that described color of object matches, thus determining that this first pixel gray level value combines according to this GTG interval.If this target sub-pixel point is this blue subpixels point, then the combination of this first pixel gray level value includes the grey decision-making of red sub-pixel point and the grey decision-making of green sub-pixels point.Thus the grey decision-making of its correspondence can be exported respectively show to carry out color by red sub-pixel point and green sub-pixels point, indicate a need for the color of object (or its close color) of display, and close the driving of this blue subpixels point, decrease the lighting time of target sub-pixel point.
Further alternative, also can according to whether the current attenuation index of each sub-pixel point of default interval detection screen pixels changes.If changing, closedown driving such as through a period of time processes, effectively slow down the decay of blue subpixels point, now detect that the damped expoential of red sub-pixel point is the highest, then can close the driving of red sub-pixel point, and by calling green sub-pixels point and blue subpixels point carries out color and shows, etc..Correspondingly, this preset pixel gray level look-up table includes the first pixel gray level value combination of the grey decision-making of the target sub-pixel dot information various Show Colors corresponding with this target sub-pixel point (GTG is interval) and corresponding other two the sub-pixels included except this target sub-pixel point thereof.
In embodiments of the present invention, can by preset the first pixel gray level value combination including various Show Color and correspondence thereof, make it possible to need the target gray scale value of display by obtaining the target sub-pixel point that in screen pixels, damped expoential is the highest, and whether detect this target gray scale value lower than preset gray scale threshold value, thus close the driving of this target sub-pixel point when detecting lower than preset gray scale threshold value, and export grey decision-making during the first pixel gray level value of its correspondence combines by the sub-pixel point called in this screen pixels except this target sub-pixel point except and show carrying out color, do not recall this target sub-pixel point, thus decreasing the lighting time of this target sub-pixel point, slow down the rate of decay of this target sub-pixel point, reduce loss, thus extend its life-span, improve image show uniformity.
Further, the schematic flow sheet that Fig. 3, Fig. 3 are another pixel call methods that the embodiment of the present invention provides is referred to.Concrete, the described method of the embodiment of the present invention can be applied particularly in above-mentioned terminal, the display screen of described terminal is made up of at least one screen pixels, each screen pixels includes red sub-pixel point, green sub-pixels point and blue subpixels point, as it is shown on figure 3, the described pixel call method of the embodiment of the present invention may comprise steps of:
301, preset pixel gray level look-up table.

Wherein, described target sub-pixel point can be the red sub-pixel point in described screen pixels, green sub-pixels point or blue subpixels point.This preset pixel gray level look-up table then can include the various Show Colors (GTG interval) corresponding with this target sub-pixel point and the first corresponding pixel gray level value combination thereof and the combination of the second pixel gray level value.
Optionally, before the target sub-pixel point in the described screen pixels of described acquisition needs the target gray scale value of display, when determining this target sub-pixel point, also by detecting the damped expoential of each sub-pixel point in screen pixels respectively；Damped expoential according to each sub-pixel point described determines the sub-pixel point that in described screen pixels, damped expoential is the highest, using sub-pixel point the highest for described damped expoential as target sub-pixel point.It is thus possible in time the sub-pixel point that current attenuation index is high is compensated, reduce its lighting time, to slow down decay, reduce loss.
303, judge that whether described target gray scale value is lower than preset gray scale threshold value.
304, close the driving of described target sub-pixel point, and obtain the color of object that described screen pixels needs to show.
Wherein, this color of object can be specially a RGB grey decision-making combination, the Show Color namely determined by the respective grey decision-making of RGB.
