Description
Technical field
The utility model relates to luminescence display field, in particular to a kind of OLED pixel, OLED pixel layer, OLED display screen
And electronic display unit.
Background technique
With the development of semiconductor technology, OLED display screen in electronic product using more and more extensive.The prior art
In, the arrangement of pixel is usually the RGB arrangement mode of standard in OLED display screen, and the RGB arrangement of standard is the arrangement of most standard
Mode, the pixel of a box-shaped is divided into trisection by it, and each piece assigns different colors, can be formed by this way
One colour cell；This is also pixel arrangement structure used by most liquid crystal displays.But due to use it is red,
Green, the primary colors sub-pixel service life is not equally to grow, and red, blue, the service life of green sub-pixels are relatively short, specifically
Ground, red, the service life of blue subpixels are longer than the service life of green sub-pixels.If traditional RGB that electronic display unit uses
Arrangement mode, that is difficult to the service life for guaranteeing OLED display screen after sub-pixel density is more than 300ppi, except non-replaceable
The luminescent material of sub-pixel, but there are technical bottlenecks for the research and development of luminescent material at present.
Therefore, how in the case where guarantee electronic display unit relatively accurate display color of image, extend making for OLED
It is those skilled in the art's urgent problem to be solved with the service life.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of OLED pixel, OLED pixel layer, OLED display screen and
Electronic display unit is realized in the case where guarantee electronic display unit relatively accurate display color of image, extends making for OLED
Use the service life.Its concrete scheme is as follows:
A kind of OLED pixel, including red, green and blue sub-pixel；Wherein,
The area of green sub-pixels is greater than red, blue subpixels areas.
Optionally, the basic unit includes with m sub-pixel of the form arrangement of M row N column；Wherein, M, N are greater than 1
Integer；M=M*N；Every row includes red, green and blue sub-pixel；The area of green sub-pixels is greater than red, the sub- picture of blue
The area of element.
Optionally, the basic unit includes with m sub-pixel of the form arrangement of M row N column；Wherein, every row includes red
Color, green and blue sub-pixel；Red, blue subpixels areas are the a/A of the area of green sub-pixels, wherein A, a are big
In 1 integer.
Correspondingly, the invention also discloses a kind of OLED pixel layer, including n above-mentioned OLED pixel, wherein n
For the integer greater than 1.
The invention also discloses a kind of OLED display screens, including above-mentioned OLED pixel layer.
The invention also discloses a kind of electronic display unit, above-mentioned OLED display screen.
A kind of OLED pixel provided by the utility model forms substantially single including red, green, blue three sub-pixels
Member；Wherein, in basic unit, the area of green sub-pixels is greater than red, blue subpixels areas.As it can be seen that the utility model
By changing the area of red, three sub-pixel of green and blue, guaranteeing that electronic display unit is relatively accurate aobvious to realize
In the case where showing color of image, extend the service life of OLED；Specific process can be illustrated by following processes:
Assuming that red, green and blue original intensities are X, red, blue subpixels service life are t1, green sub-pixels
Service life be t2, wherein t1Greater than t2, that is, glow slow with the decaying of the ratio green luminescent material of the material of blue light decaying.Existing
In technology, after the Δ t time, when the brightness decay of feux rouges and blue light is 0.8X, the brightness decay of green light sub-pixel is
0.6X since the contrast of 0.8X and 0.6X is more than preset contrast threshold, for example can be 0.18X, at this point, being by brightness
The color for the OLED display screen that the green sub-pixels that red, blue subpixels and the brightness of 0.8X is 0.6X are constituted will be no longer quasi-
Really, cause OLED display screen that cannot use, i.e. the service life of OLED display screen is Δ t.And use OLED provided by the utility model
Pixel, since red, blue subpixels area is less than green sub-pixels, red, blue original intensity is 0.9X,
The original intensity of green is 0.8X, after the same Δ t time, when the brightness decay of feux rouges and blue light is 0.7X, and green light
The brightness decay of sub-pixel is 0.6X, since the contrast of 0.7X and 0.6X is less than above-mentioned preset contrast threshold 0.18X, this
When, the face for the OLED display screen that the green sub-pixels that the red, blue subpixels and the brightness that are 0.7X by brightness are 0.6X are constituted
Color is still in the range of allowing use, i.e. the service life of OLED display screen is at least more than Δ t.So provided by the utility model
OLED pixel extends the service life of OLED display screen in the case where guaranteeing that electronic display unit can be used.
Detailed description of the invention
