Display panel pixel

Abstract

The invention discloses a display panel pixel comprising a first transistor, a first electrode, a second electrode and a first gate electrode; the first electrode is used to receive a data signal; the first gate electrode is used for receiving a scan signal; the light emitting unit is provided with a first end and a second end; the second end is coupled to the first voltage source; and a second transistor is provided with a third electrode, a fourth electrode and a second gate electrode; the second gate electrode is coupled to the second electrode; the fourth electrode is coupled to the first end of the light emitting element; the distance difference between the first gate electrode parallel to the first and second electrode wire width and the first electrode and the second electrode is greater than that of the second gate electrode in parallel between the third and fourth line of the width of the electrode and the third electrode and the fourth electrode.

Description

technical field [0001] The present invention relates to a pixel of a display panel, in particular to a transistor structure in a pixel of a display panel. Background technique [0002] An organic light emitting diode display is a display device that uses organic light emitting diode pixels to emit light to display images. The brightness of an OLED is proportional to the magnitude of the current flowing through the OLED. Generally, an OLED pixel includes two transistors, one is a switching transistor and the other is a driving transistor. The switch transistor is used to control the writing of the data signal according to the scanning signal, and the driving transistor is used to control the magnitude of the driving current flowing through the OLED according to the voltage of the written data signal. [0003] However, in the prior art, both the switching transistor and the driving transistor of the OLED pixel are fabricated in the same manufacturing process, that is to say,...

Problems solved by technology

[0003] However, in the prior art, both the switching transistor and the driving transistor of the OLED pixel are manufactured in the same manufacturing process, that is to say, the sub-threshold swings of the switching transistor and the driving transistor of the existing OLED pixel are the same , the above situation may cause the characteristics of the switching transistor and / or driving transistor to not meet the design requirements
