Embodiment Construction

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0038] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the description in the accompanying drawings directions for the example described above. It will be appreciated that if the illustrated device is turned over so that i...

Abstract

The present invention relates to the field of display technology, and proposes a display panel, the display panel includes a bending area for bending, and the display panel also includes: a detection pixel unit, a detection line, a calculation module, a compensation module, and a detection pixel unit The dummy pixel unit located in the bending area is used as the detection pixel unit; the detection line is connected to the detection pixel unit in the same column to detect the driving current of the detection pixel unit; the calculation module is connected to the detection pixel unit line, used to detect the amount of change in the driving current of the detection pixel units in each row before and after the bending of the display panel; the compensation module is connected to the calculation module, and is used to compensate the light-emitting pixel units in the corresponding row according to the amount of change in the driving current data signal, so as to reduce the change amount of the light-emitting driving current before and after the light-emitting pixel unit is bent. The display panel provided by the present disclosure can avoid abnormal display caused by bending.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a driving method thereof. Background technique [0002] In recent years, flexible and foldable products have attracted much attention. In the related art, the driving array substrate of the display panel is usually manufactured using Low Temperature Polysilicon (LTPS, Low Temperature Poly-silicon) technology. Due to the strain effect of the metal layer and the semiconductor polysilicon in the display panel, when the display panel is bent, the metal wires and the semiconductor polysilicon will be deformed (elongated or shortened) along their axis, thereby causing their resistance value to change accordingly. [0003] Therefore, during the folding process of the flexible display panel, due to the change of metal and semiconductor resistance, the output current of the pixel driving circuit will change, and the change of the output current of the pixel dr...
