Perhaps "lower" can also be indirectly formed by intermediary element in another element "upper" or "lower" for a element "upper".
Before the detailed technical solution for illustrating the present embodiment, organic light emitting display panel that the present embodiment is related to
And technical problem is simply introduced:
Organic light emitting display panel includes multiple light emitting diodes, and light emitting diode includes anode, cathode and setting two
Organic layer between person.Organic layer can emit the light of the electric current corresponding brightness rank between anode and cathode.Specifically, driving
Circuit to the both ends of light emitting diode provide driving voltage (PVDD and PVEE), by control anode and cathode between electric current come
Show desired image.
But the distance between light emitting diode and driving circuit are longer, the decaying of received driving signal is bigger,
I.e. pressure drop is bigger, then leads to display brightness of the light emitting diode far from driving circuit end and the display brightness at nearly driving circuit end not
Together, cause the brightness of entire organic light emitting display panel inconsistent, when the size of especially organic light emitting display panel is larger more
It is obvious.
In order to improve the display effect of organic light emitting display panel, so that bright in organic light emitting display panel each region
Uniformity is spent, the mode of double drive can be used, i.e., be respectively provided with driving circuit in the two sides of organic light emitting display panel, although subtracting
The small length of cabling, improves the decaying of driving signal, but will lead to the non-display area face of organic light emitting display panel
Product increases, and further increases frame size, the more serious arrangement that can also change cabling, increases panel design difficulty.
Alternatively, acquiring the brightness value of each pixel, the pixel darker to brightness carries out luminance compensation, to the higher picture of brightness
Element is modified, so that the brightness in organic light emitting display panel in each region is more uniform.It is mended by external optical
The scheme repaid needs to acquire the brightness under each pixel difference grayscale value, for example, for resolution ratio 1080p, the display screen meeting
By 1920 × 1080 pixels, it is very big for acquiring the workload of the brightness of each pixel.It is high to compensate difficulty, for high-resolution
For rate, big display screen, compensation difficulty is just bigger.
In order to solve the problems, such as the brightness disproportionation of organic light emitting display panel each region, inventor proposes following technical side
Case:
The present embodiment provides a kind of display processing methods, and as shown in Figure 1 to Figure 3, Fig. 1 is provided by the embodiment of the present invention
A kind of flow diagram of display processing method, Fig. 2 are one kind of organic light emitting display panel provided by the embodiment of the present invention
Structural schematic diagram, Fig. 3 are grayscale-brightness curve provided by the embodiment of the present invention, which includes:
S101, organic light emitting display panel is divided into several display blocks.Illustratively as shown in Fig. 2, this is organic
Light emitting display panel 100 divides for 4 display blocks, respectively the first display block A1, the second display block A2, third viewing area
Block A3 and the 4th display block A4.
In organic light emitting display panel, since voltage supply belt carrys out pressure drop, the brightness irregularities of display panel are caused, therefore
In the present embodiment, display block can be divided according to voltage attenuation direction, i.e., be divided according to luminance difference, facilitated subsequent aobvious to this
Show that block carries out luminance compensation.
Further, organic light emitting display panel is divided into several display blocks in step S101, comprising: will be adjacent
And luminance difference preset value region division in the same display block, preset value a, a≤± 10%.That is, right
It in the division of display block, is determined with luminance difference, it is not related with the area of each display block.
Since the quantity for dividing display block is fewer, subsequent workload is with regard to smaller, still, divides the quantity of display block
More, the brightness homogeneity of entire organic light emitting display panel is higher, therefore after taking into account brightness and workload, the present embodiment
Luminance difference is enabled to be less than in ± 10% and adjacent region division to same display block, so as to improve organic light emitting display panel
Brightness uniformity and reduce workload, improve working efficiency.
The area of each display block is not defined in the present embodiment, the area of each display block can integrate
The entire area and luminance difference degree of machine light emitting display panel are divided.It can be divided in luminance difference visibility point aobvious more
Show block, the area of each display block is inevitable just small herein, conversely, can be by the face of display block in the small position of luminance difference
Product suitably tunes up, and finally makes the brightness uniformity in each display block consistent.
The brightness value of S102, each display block of detection, wherein corresponding to the smallest display block of brightness value is benchmark area
Block, the brightness of benchmark block are benchmark brightness.Illustratively, 4 display blocks are still included with organic light emitting display panel 100
For, detect the brightness value of each display block.Wherein, in conjunction with shown in Fig. 2 and Fig. 3, the first display block A1 is in any grayscale
Brightness under value is respectively less than remaining display block, therefore can be benchmark display block by the first display block A1.Reference region
Block can be understood as the brightness references block of all display blocks in organic light emitting display panel 100.Further, the first display
The corresponding brightness value of block A1 can be regarded as Benchmark brightness.
Illustratively, still as shown in connection with fig. 3, if using the 4th display block A4 as benchmark block, then the 4th display
Block A4 corresponding display brightness in 255 grayscale is 600nit or so, but third display block A3, the second display block A2
And first display block A1 do not reach the grayscale value of 600nit and be corresponding to it, will lead to third display block in this way
A3, the second display block A2 and the first display block A1 can not be shown.Therefore, by the smallest viewing area of brightness value in this implementation
Block can avoid the spilling of brightness, ensure that the normal display of organic light emitting display panel as benchmark block.
Further, the brightness value of each display block is detected in step S102, comprising:
Choose representative luminance value of the brightness of display block central area as corresponding display block.It illustratively can be such as
Shown in Fig. 2, the brightness of display block A1 central area X is as its representative luminance value.
Since the brightness of central area can be used as its representative luminance value, thus the whole for avoiding acquisition display block from being included
The brightness data of pixel, data acquisition are relatively easy.
The corresponding grayscale value of brightness of S103, each display block of acquisition, the grayscale-for establishing organic light emitting display panel are bright
It writes music line.Illustratively as shown in figure 3, the first display block A1, the second display block A2, third display block A3 and the 4th are aobvious
Show that block A4 establishes respective grayscale-brightness curve.
Further, in conjunction with shown in Fig. 2 and Fig. 3, the corresponding grayscale of brightness of each display block is acquired in step S103
Value, comprising:
Acquire brightness value corresponding to 0 to 255 grayscale in each display block.Illustratively, Fig. 3 respectively illustrates first
Display block A1, the second display block A2, the brightness of third display block A3 and the 4th display block A4 and gray value variation
Curve.
S104, according to grayscale-brightness curve, record the grayscale value that each display block corresponds to Benchmark brightness, wherein right
It should be correction grayscale value in the grayscale value of Benchmark brightness.Illustratively as shown in figure 3, the first display block A1 is benchmark block,
For using 400nit as the Benchmark brightness of 231 grayscale, grayscale value when the first display block A1 corresponds to Benchmark brightness 400 is
Correction grayscale value when 231, the second display block A2 correspond to Benchmark brightness 400 is 223, and third display block A3 corresponds to base
Correction grayscale value when quasi- brightness 400 is 216, and correction grayscale value when the 4th display block A4 corresponds to Benchmark brightness 400 is
209。
In display brightness, display screen can generally be adjusted to corresponding grayscale value.Illustratively, to show that 400nit is
Example can be adjusted to corresponding grayscale value, such as it is 231 that 400nit, which corresponds to grayscale value,.At this point, for the first display block A1 and
Speech, due to the corresponding 400nit of grayscale value 231, the display brightness of the first display block A1 is 400.But for the second display
For block A2, if the grayscale value of the second display block A2 is adjusted to 231, corresponding brightness is about 434nit；It is similar
, the corresponding brightness of grayscale value 231 of third display block A3 is about 466nit；The grayscale value 231 of 4th display block A4
Corresponding brightness is about 498nit.The different location of entire organic light emitting display panel shows different brightness, causes brightness
Inhomogenous, display effect is poor.
And in the present embodiment, using the first display block A1 as benchmark block, corresponding brightness is benchmark brightness, still
By taking brightness 400 as an example, when it is 400nit that organic light emitting display panel, which needs display brightness, the grayscale value of the first display block A1
It is 231, the second display block A2, third display block A3 and the 4th display block A4 are adjusted to its corresponding correction grayscale value,
So that the brightness of three display blocks and the brightness of benchmark block are consistent, and then organic light emitting display panel each region
Brightness uniformity is consistent, improves display effect.
It should be noted that Benchmark brightness refers to brightness value corresponding to the grayscale of benchmark block, that is to say, that reference region
Block corresponds to how many a grayscale values, will include how many a Benchmark brightness values.
S105, the correction grayscale value that all display blocks correspond to Benchmark brightness is found out.Such as foregoing description, according to foundation
Grayscale-brightness curve, find each display block correspond to Benchmark brightness correction grayscale value.
It is understood that the corresponding brightness of benchmark block is benchmark brightness, it is corresponding with Benchmark brightness to can be regarded as base
The grayscale value of quasi- grayscale value or benchmark block, and the grayscale value that remaining display block corresponds to Benchmark brightness can be referred to as
Correct grayscale value.
Illustratively, the correction grayscale value that each display block corresponds to Benchmark brightness is recorded, it may include with the shape of table
Formula records the grayscale value that each display block corresponds to Benchmark brightness.Facilitate subsequent lookup correction grayscale value.As shown in table 1 below,
It is the relationship of display brightness and grayscale value.
Table 1
As shown in table 1, according to the respective corresponding correction grayscale value of each display block, the display of four display blocks is bright
Degree reaches unanimity, so that the brightness that entire organic light emitting display panel is shown reaches unanimity, improves organic light emitting display
The display effect of panel.
S106, correction grayscale value is converted into voltage input to corresponding display block.Since brightness is corresponding corresponding
Grayscale value is corrected, can be directly corresponding with voltage value by brightness when correction grayscale value is corresponding with voltage, consequently facilitating driving
The data at end input, and simplify finding step.
By the way that organic light emitting display panel is divided into several display blocks in the present embodiment, each display block is detected
Brightness value can avoid the spilling of brightness, ensure that organic and using the minimum display block of wherein brightness value as benchmark block
The normal display of light emitting display panel.And then the corresponding grayscale value of brightness of each display block is acquired, it is aobvious to establish organic light emission
Show grayscale-brightness curve of panel；According to grayscale-brightness curve, the grayscale that each display block corresponds to Benchmark brightness is recorded
Value, wherein removing the display block except benchmark block can be used as correction grayscale value corresponding to the grayscale value of Benchmark brightness, thus
The correction grayscale value of the display block and benchmark block same brightness that are removed except benchmark block.Find out all viewing areas
Block corresponds to the correction grayscale value of Benchmark brightness, and correction grayscale value is converted into voltage input to corresponding display block,
When holding display image data before treatment, the corresponding voltage of revised correction grayscale value is delivered to corresponding display block,
It realizes that each block display brightness is consistent, improves the display effect of organic hair display panel.
For improving display effect by the way of double drive, this implementation, can while improving display effect
The frame size for avoiding increasing organic light emitting display panel, reduces cabling difficulty.
Relative to the brightness value for acquiring each pixel, the opposite mode that carries out luminance compensation darker to brightness, this implementation
While improving display effect, the brightness for acquiring each pixel is not needed, unwanted calculating penalty coefficient, it is only necessary to look into yet
The voltage corresponding to Benchmark brightness is found out, working procedure is simplified.
