AI Technical Summary

Benefits of technology

The present invention is about a display panel that prevents color distortion over a fixed range. The panel has pixels with different aperture ratios, which ensure the same current densities on the pixels. This results in no color shifting even after extended use of the display. The technical effect of this invention is a display panel that consistently looks good, even after extended use.

Problems solved by technology

After display for a long time, attenuations of different materials are inconsistent with respect to the lifetime of the materials.
This result in color shifting in the display panel.

Embodiment Construction

[0047]The term “embodiment” as used in this specification means an embodiment, an example, or an illustration. In addition, the article “a” as used in the specification and the appended claims may be construed as “one or more.” The singular form can be clearly defined unless otherwise specified or from the context.

[0048]Any two of a first embodiment, a second embodiment, a third embodiment, and a fourth embodiment of a display panel 10 of the present disclosure are similar or same.

[0049]In the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment of the present disclosure, the display panel 10 can be, for example, an organic light emitting diode (OLED) panel or the like.

[0050]The display panel includes at least two pixel repeating units, and the at least two pixel repeating units are arranged in an array (one-dimensional array or two-dimensional array). The pixel repeating unit includes one first pixel 101, one second pixel 102, one third pixel 103...

Abstract

A display panel has a ratio y1 of an aperture ratio of the red pixel to an aperture ratio of the green pixel being in the range of 0.78e{circumflex over ( )}(−1.98r) ≤y1≤2.297e{circumflex over ( )}(−1.85r), and 0.1≤y1≤3, where r is a ratio of a luminous efficiency of the red pixel to a luminous efficiency of the green pixel. A ratio y2 of an aperture ratio of the blue pixel to the aperture ratio of the green pixel is in a range of 1.32e{circumflex over ( )}(−10.7b) ≤y2≤5.95e{circumflex over ( )}(−14.1b), and 0.3≤y2≤4, where b is a ratio of a luminous efficiency of the blue pixel to the luminous efficiency of the green pixel.

Description

FIELD OF INVENTION[0001]The present disclosure relates to the field of display technologies, and more particularly to a display panel.BACKGROUND OF INVENTION[0002]Luminescent material layers of pixels in conventional organic light emitting diode (OLED) display panels are generally formed by evaporation processes.[0003]In the formed pixels, areas of red pixels, areas of green pixels, and areas of blue pixels only consider the optical effect when the organic materials are optimally illuminated. After display for a long time, attenuations of different materials are inconsistent with respect to the lifetime of the materials. This result in color shifting in the display panel.[0004]Therefore, it is necessary to propose a new technical solution to solve the above technical issues.SUMMARY OF INVENTION[0005]An object of the present disclosure is to provide a display panel capable of preventing color drift from being over a predetermined range.[0006]In order to solve the above issues, a tech...
