The OLED (Organic Light-Emitting Diode) display technology has the characteristics of self-luminescence, wide viewing angle, wide color gamut, high contrast, lightness, thinness, foldability, bendability, lightness, thinness, portability and the like, and the bending folding and flexible display are the main research and development directions in the current display field.
The curved display panel in the prior art comprises a flat display area and an arc-shaped edge area positioned outside the display area, and when the infinitesimal size of the flat display area approaches or reaches zero, the curved display panel can also become a flexible display panel.
According to the development requirements of the existing OLED flexible display, the OLED flexible curved screen is in various shapes such as side fixing bending, curling screen Wing and flexible wearing. Generally, according to actual product experience, the warped image quality is affected by various factors such as the difference between RGB transmittances of functional elements of a Panel (display Panel), or bending of an anode, and the like, and the image quality at a warped portion (including a fixed warped portion and a flexible warped portion deformed by an external force) is often abnormal such as yellowing and bluish, and such abnormal image quality seriously affects the display image quality of the display Panel.
After a cathode layer, an encapsulation layer, a polarizer and a CG (Cover Glass, which has a multilayer structure and can be called as a functional component layer) layer are prepared on a light emitting layer of a curved display panel, in the display process, due to the bending reason, when the bending angle is increased, the light transmittance of blue light is relatively gradually reduced, and the light transmittance of red light and green light is increased, so that the proportion of light emitted by all light emitting units is unbalanced, white light cannot be synthesized, and the phenomenon that human eyes observe the curved area to cause yellowing is generated, which will be explained below by combining specific data.
Fig. 1 is a normalized spectrum diagram of light transmittance of each color at different angles, in an exemplary embodiment of the invention, the transmittance of Red (R, Red), Green (G, Green) light of an OLED display panel with a functional element (CG) layer is increased compared to the transmittance of the OLED display panel without the CG layer; meanwhile, as the bending angle of the display panel increases, the intensity of Blue (B, Blue) transmittance light gradually decreases with respect to red (R) and green (G) lights, and correspondingly, the intensity of red and green light transmittance lights increases.
Referring to fig. 1, when the bending angle is 0 °, the intensity of blue light is the strongest and sharpest than those of red light and green light, and when the bending angle is 60 °, the difference in transmitted light intensity between the three RGB light beams is reduced, and the intensity appears to be nearly flat. Namely, under the influence of the CG layer, the blue light transmittance is slightly reduced relative to red light and green light; with the influence of the larger bending angle, the blue light transmission light intensity is seriously attenuated, and correspondingly, the red light transmission light intensity and the green light transmission light intensity are increased, so that the three primary colors RGB brightness in the bending area is not in accordance with the proportion of synthesized white light compared with the non-bending area, and the problem of yellow image quality in the bending area is caused.
Fig. 1 shows that the weaker the blue spectrum, the more pronounced the side yellowing as the CG bend angle increases.
Fig. 2 is a data diagram illustrating transmittance decrease caused by the influence of the polarizer on light of different colors, where Tr Drop is transmittance decrease, Tr is transmittance, Pol is polarizer, and the attenuation speed of the transmission light intensity of the three primary colors of RGB is also influenced by the polarizer of the functional module, as shown in fig. 2. The RGB three-primary-color transmittance is reduced to be consistent when the bending angle of the polarizer is pi/2, and the blue light transmittance is reduced to the maximum when the bending angle of the polarizer is changed to be pi, namely the attenuation intensity of the blue light transmission is faster than that of the red light and the green light, and the phenomenon of yellowing of image quality in a bending area is aggravated.
Fig. 2 shows that under Pol large angle bending conditions, Tr for blue and green light attenuates more quickly than red light, which correspondingly exacerbates the side yellowing phenomenon.
Fig. 3 shows a light transmission spectrum at a central viewing angle of 60 ° and an edge bend of the display panel, where the light transmission spectrum at the edge bend is an L-W curve (blue curve), the intensity of blue light transmission light is seriously attenuated compared with the light transmission spectrum W-L curve (red curve) at the central viewing angle of 60 °, the intensities of red light and green light are enhanced and half-wave widths are increased, that is, the main cause of abnormal image quality in the bend area is that the intensity of blue light transmission light is seriously attenuated, so that the ratio of RGB to white light is no longer in an optimal state.
Fig. 3 shows that the attenuation of blue light is relatively more severe at the side positions, the red-green half-wave width is widened, and the peak positions are red-shifted.

In a possible implementation manner of the exemplary embodiment of the present invention, the colors of the first color, the second color and the third color may be other colors besides the three colors of red, green and blue according to specific display requirements, and the present invention is described by taking the three colors of red, green and blue as an example.

When the display panel is bent, one or more corresponding pixel structures can sense and bear stress caused by the bending, correspondingly, a piezoelectric module, namely a forward light-emitting diode electrically connected with a piezoelectric field effect transistor, which is matched with a regulation sub-pixel included in each pixel structure is conducted after the piezoelectric module is stressed, the light-emitting diode is a part of the regulation sub-pixel, the regulation sub-pixel further comprises a mos part, a cathode part and the like, so that the regulation sub-pixel is lightened, and when the stress disappears, a regulation passage formed by the piezoelectric field effect transistor is closed, the corresponding light-emitting diode is cut off, and the corresponding regulation sub-pixel is closed.
As shown in fig. 9, when the display panel is bent, the piezoelectric field effect transistor induces bending deformation and bending stress to make the semiconductor material of the gate generate charge polarization on the structure to generate a piezoelectric potential, and when the piezoelectric potential is greater than a threshold voltage, the corresponding channel of the piezoelectric field effect transistor is opened to make V be larger than VDDThe LED can be driven to light and emit light, so that the curved screen can be adaptively improved in curved image quality.
The piezoelectric field effect transistor is sensitiveThe structure of the piezoelectric field effect transistor according to the exemplary embodiment of the present invention is shown in fig. 10, which is a schematic structural diagram of a nano-zinc oxide and SWNT mixed field effect transistor, and a piezoelectric potential generated by applying a strain to the outside of the nano-zinc oxide is used as a gate voltage to control carrier transport in the SWNT-based current channel located below. Zinc oxide Nanowires (NWs) were used as the passive and contactless gates. When 0.05% strain is applied along the ZnO nanowire used in the same device, the source-drain current IDSThe sudden increase and the compressive potential at 0.05% strain was 0.65 v. In an exemplary embodiment of the present invention, a piezoelectric potential of 0.65V can be generated by 80nN force, and the threshold voltage is typically-1.5V, so that the piezoelectric field effect transistor can be turned on to receive a corresponding data signal to drive the control sub-pixel electrically connected thereto.
In the display panel with the fixed bending part, the regulating sub-pixels are additionally arranged at the bending part, and the bending part continuously exists due to the bending stress, so that the regulating sub-pixels can be arranged according to the corresponding VdataAdjusting the brightness of the signal to enable the brightness of the display screen at the bent part to be recovered to be normal from the abnormal state of the image quality; in the flexible display panel, a regulation sub-pixel comprising three colors as shown in fig. 8 can be additionally arranged in each RGB array of the whole display panel, so that the regulation path of the regulation sub-pixel of the corresponding bending portion of the flexible display panel is in an open state according to the corresponding V when the flexible display panel is bentdataThe signal adjusts its brightness.
In the exemplary embodiment of the present invention, it should be noted that, in the case that the modulation path is opened, the corresponding modulation sub-pixel is lighted by VDDControlled, and the brightness of the LEDs is adjusted by the received VdataThe signal is controlled.
In the exemplary embodiment of the invention, when the bending part of the flexible bending screen has abnormal yellow image quality and the transmission light intensity of blue light is reduced due to the reasons, a regulation sub-pixel is additionally arranged on the basis of the original pixel arrangement RGB, the regulation sub-pixel is a blue light sub-pixel, and the size of the regulation sub-pixel is matched with the actual requirementDesigned by considering the proportion of blue light to be adjusted, the pixel arrangement of the exemplary embodiment of the present invention is changed from original RGB (fig. 4) to RGBB (fig. 5), and accordingly, the blue control sub-pixel is a corresponding piezoelectric module in a matching manner, the piezoelectric module is a high-sensitivity stress-induced piezoelectric field effect transistor, such as a piezoelectric field effect transistor whose gate is made of a piezoelectric semiconductor material, such as nano zinc oxide material, and when the display panel is bent and deformed, the piezoelectric field effect transistor generates a piezoelectric potential on the gate to turn on the corresponding channel, and at this time, the piezoelectric field effect transistor is used as a wire capable of transmitting the corresponding received VdataSignal, further according to the VdataThe signal makes the light emitting diode adjust the brightness, so that the image quality of the bending part is improved.
