The display screen control device 100 of embodiment of the present invention comprises timing module 10 and driver module 20.Timing module 10 is for recording the displaying time of OLED display screen.The displaying time section of driver module 20 for falling into according to described displaying time, adopts corresponding driving to arrange and drives the display of described OLED display screen.
The display panel control method of embodiment of the present invention can be realized by the display screen control device 100 of embodiment of the present invention.Such as, step S1 can be realized by timing module 10, and step S2 can be realized by driver module 20.
Under normal circumstances, the basic structure of OLED is by the indium tin oxide of a thin and transparent tool characteristic of semiconductor, is connected, adds a metallic cathode with the positive pole of electric power.Structural sheet comprises: hole transmission layer, luminescent layer and electron transfer layer.When supplying power to appropriate voltage, positive pole hole and negative electrode electric charge combine in luminescent layer, produce light, produce red, green and blue RGB three primary colors, form basic color according to its material difference.
Usually, the color of each pixel in OLED display screen is determined by the view data of rgb format.Under normal circumstances, red, green, blue three Color Channels are divided into 255 rank brightness by the view data of rgb format separately.Such as, the RGB data that certain pixel is corresponding is (0,0,0), and so this pixel just presents black.And for example, the RGB data that certain pixel is corresponding is (255,255,255), and so this pixel just presents white.As mentioned above, specific RGB data correspond to the specific color of pixel.
Display driver in OLED display screen, according to the view data of rgb format, drives the organic light emitting diode of red, green, blue three Color Channels to send the primaries of different gray-scale intensity.After the primaries display effect superposition of these different gray-scale intensity, specific color can be presented.But along with the growth of OLED display screen service time, the luminescent material of Organic Light Emitting Diode is decayed, under same driving is arranged, the display brightness of Red Green Blue can reduce accordingly, and then causes display frame to produce colour cast problem.
Thus, can according to the displaying time of OLED display screen, adopt corresponding driving to arrange, thus solve because luminescent material is decayed the colour cast problem brought.
Particularly, exemplarily, suppose that the RGB data of certain pixel is for (a, b, c), during original state, the driving brightness value of display screen is (m

So, can effectively solve in the use procedure of Organic Light Emitting Diode (OrganicLight-EmittingDiode, OLED) display screen, the colour cast problem produced because decay occurs luminescent material.
Refer to Fig. 3 and Fig. 4, in some embodiments, before step S1, also comprise step S0:
Determine that the described driving of multiple described displaying time sections and multiple correspondence is arranged, the corresponding described driving of each described displaying time section is arranged.
Display screen control device 100 also comprises and arranges module 30.Arrange module 30 for determining that the described driving of multiple described displaying time sections and multiple correspondence is arranged, the corresponding described driving of each described displaying time section is arranged.
Step S0 in the display panel control method of embodiment of the present invention can realize by arranging module 30.
Particularly, exemplarily, first the attenuation of module 30 according to luminescent material be set, determine multiple displaying time section, such as 0-500 hour, multiple time period such as 500-1000 hour, 1000-1500 hour.Meanwhile, module 30 is set and determines the driving setting that each time period is corresponding, such as 0-500 hour corresponding drive factor m

0a, n
0b, k
0c).Drop within the scope of the time period of 500-1000 hour when displayed, driver module 20 adjusts corresponding driving and is arranged so that display screen drives brightness value to become (m
1a,n
1b,k
1c).Drop within the scope of the time period of 1000-1500 hour when displayed, driver module 20 adjusts corresponding driving and is arranged so that display screen drives brightness value to become (m
2a,n
2b,k
2c), the like.
Be appreciated that the division of described displaying time section can be arranged depending on concrete condition.When described displaying time section divides abundant, described OLED display screen can be avoided occurring serious colour cast problem for a long time.
So, can in multiple time period, adopt corresponding driving to arrange and drive the display of described OLED display screen, make described OLED display screen correspondingly can compensate the reduction of the luminosity brought because of luminescent material decay in different time sections, and then avoid occurring serious colour cast problem.
