Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the cross-sectional view of OLED display panel in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention provides a kind of OLED display panel, too low for solving existing OLED display panel resolution ratio
Technical problem.
Technical solution in order to enable those skilled in the art to better understand the present invention, below in conjunction with of the invention real
The attached drawing in example is applied, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without making creative work, all should belong to protection of the present invention
Range.
As shown in Figure 1, OLED display panel 100 includes pixel layer 10 and switching layer 20, pixel layer in the embodiment of the present invention
10 and switching layer 20 between the first substrate 30 and the second substrate 40.
Pixel layer 10 includes several pixel units 11, these pixel units 11 are arranged in array, between each pixel unit 10
With interval, the quantity and array of pixel unit 11 can be adjusted according to the application scenarios of OLED display panel.Such as
Plain unit 11 can be set to single-row or uniline pattern arrays, can also be arranged to be uniform or staggered the rows and columns battle array of arrangement
Column.
In practical applications, pixel layer 10 can be deposited obtained by fine metal mask plate, this is common for this field
Technology known to technical staff, and be not the focus of this case, this will not be repeated here.
In embodiments of the present invention, each pixel unit 11 may each comprise red sub-pixel 111, green in pixel layer 10
Pixel 112 and blue subpixels 113, sub-pixel is both configured to emit light towards light direction in each pixel unit 10, and
And belong between each sub-pixel of the same pixel unit 10 and also can have being left white for certain size, with guarantee each sub-pixel it
Between be not in colour mixture.
Among the array of pixel unit 11, sub-pixel can be used identical in each row, each pixel unit 10 respectively arranged
Juxtaposition type arrangement, to form the picture of 113 sequence cycle arrangement of red sub-pixel 111, green sub-pixels 112 and blue subpixels
Plain row and pixel column.Certainly, the arrangement of sub-pixel can also be different in each pixel unit, the cloth so that each color sub-pixels interlock
The pixel column or pixel column set.
Certainly, pixel unit 11 be not limited to include aforementioned color sub-pixel, can also including white sub-pixels etc.,
This is not repeated them here.
Switching layer 20 is located on the light direction of pixel layer 10, and switching layer 20 includes several switches 21, and each switch 21 wraps
Light control element 211 and driving element (not shown) are included, light control element 211 is located at the light direction of the partial region of sub-pixel
On, light control element 211 can adjust the amount of light of the sub-pixel in covered part region under the driving of driving element.?
When sub-pixel is arranged in array, light control element 211 is equally arranged in array.
It is adjusted due to being independently controlled by light element 211 there are the amount of light of the partial region of sub-pixel, and rest part region
The amount of light of sub-pixel is not adjusted then, so that the same sub-pixel is divided into two different parts of amount of light, the two
Part then forms independent two sub-pixels, so that the size of sub-pixel is lowered, realization has greater number in unit area
Sub-pixel, improve the resolution ratio of OLED display panel.
In embodiments of the present invention, light control element 211 may include phase-change material, then driving element can be to the phase
Become the power supply module of material power supply, when driving element powers to phase-change material, the light transmission of phase-change material increases, phase-change material
Light emitted by the part sub-pixel covered can penetrate phase-change material gradually, can be by adjusting the electricity of supply phase-change material
Size is flowed, to jump the light transmission of phase-change material, and then adjusts the amount of light emitted by institute's covering part sub-pixel.
Certainly, in other embodiments of the invention, light control element 211 can also be movable light shield piece, such as cantilever beam
Anti-dazzling screen can be connect by formula anti-dazzling screen with capacitor board, by adjusting the voltage of capacitor where the capacitor board, realize capacitor board
Raising and lowering, and then drive anti-dazzling screen movement, realize adjustment institute's covering part sub-pixel emitted by light amount.
In practical applications, the photocontrol member of at least two laid out in parallel can be covered on the light direction of each sub-pixel
Part 211, and each light control element 211 is under the action of respective driving element, it is different to the adjustment capability of light, thus will
Each sub-pixel is divided at least two relatively independent parts, and the amount of light of each section can control well, make
While obtaining the increase resolution of OLED display panel, can also have good color display capabilities.
In the embodiment of the present invention, the quantity of the light control element 211 on the light direction of each sub-pixel is identical, so that
Sub-pixel is evenly distributed in OLED display panel.Preferably, each photocontrol member on the light direction of same sub-pixel
The size in the region that part 211 is covered is identical, realizes a sub-pixel being divided into multiple smaller sub-pixels, so that
Sub-pixel is more evenly distributed in OLED.
Certainly, OLED display panel will also include ties such as anode layer, hole transmission layer, electron transfer layer, cathode layer
Structure, this is the conventional structure of OLED pixel unit, therefore shows in non-figure.
In conclusion OLED display panel provided in the embodiment of the present invention, by covering son in light control element 211
The partial region of pixel and the amount of light that the region is adjusted using the light control element 211, so that the same sub-pixel is divided
At two different parts of amount of light, the two parts then form independent two sub-pixels, so that the size of sub-pixel is dropped
Low, realization has greater number of sub-pixel in unit area, improves the resolution ratio of OLED display panel.
