Active matrix organic light-emitting diode pixel circuit, method for driving the same, and display device

#The present disclosure relates to a field of display technology, particularly to an Active Matrix Organic Light-Emitting Diode (AMOLED) pixel circuit, a method for driving the same, and a display device.

#With rapid development of the display technology, display devices with a touch control function are gradually popular since they have advantages such as visualization operation. In general, the existing display devices with the touch control function can be classified into display devices with an on-cell touch screen panel and display devices with an in-cell touch screen panel according to the position of the touch screen panel relative to the display panel. Compared to the on-cell touch screen panel, the in-cell touch screen panel is thinner in thickness and has a higher light transmittance.

#For the existing display devices, the Organic Light Emitting Diode (OLED), as a current type light-emitting element, is increasingly applied to the field of the high performance display, since it has characteristics such as self-luminance, rapid response, wide view angle, and capability of being manufactured on a flexible substrate, and the like. OLED display devices can be classified into Passive Matrix Driving OLED display devices and Active Matrix Driving OLED display devices, wherein since an AMOLED display device has advantages such as low cost in production, high response speed, energy-saving, direct-current driving capability available to a portable apparatus, wide operating temperature range, and the like, it tends to replace the Liquid Crystal Display to be as a next generation of a novel flat panel display. Therefore, the AMOLED display panel with the in-cell touch control function has increasingly gained favor with customer.

#In order to more clearly describe the technical solutions of the embodiments of the present disclosure or the prior art, drawings necessary for describing the embodiments of the present disclosure or the prior art are simply introduced as follows. It should be obvious for those skilled in the art that the drawings described as follows only illustrate some embodiments of the present disclosure and other drawings can be obtained according to these drawings without paying any inventive efforts.

#FIG. 1 is a schematic block diagram illustrating a structure of an AMOLED pixel circuit provided in an embodiment of the present disclosure;

#FIG. 2 is a schematic circuit diagram illustrating a structure of an AMOLED pixel circuit provided in an embodiment of the present disclosure;

#To illustrate the technical solutions of embodiments of the present disclosure clearly and fully, hereinafter, detailed descriptions will be made to the embodiments of the present disclosure in connection with the appended drawings. Obviously, the embodiments as described are only a part of the embodiments of the present disclosure, and are not all the embodiments of the present disclosure. All the other embodiments which are obtained by those skilled in the art based on the embodiments of the present disclosure without paying any inventive labor fall into the protection of the present disclosure.

#The transistors employed in all the embodiments of the present disclosure can be thin film transistors, field effect transistors, or any elements with the same characteristics. Since a source and a drain of a transistor utilized herein are symmetrical, there is no distinction between the source and the drain thereof. In the embodiments of the present disclosure, in order to make a distinction between two electrodes of a transistor other than a gate thereof, one of the two electrodes is referred to as a source, and the other is referred to as a drain. Further, a transistor can be classified into an N-type transistor or a P-type transistor based on the characteristics of the transistor; in the embodiments of the present disclosure, when the N-type transistor is employed, the first electrode can be the source, and the second electrode can be the drain, and when the P-type transistor is employed, the first electrode can be the drain, and the second electrode can be the source.

#FIG. 1 illustrates an AMOLED pixel circuit provided in an embodiment of the present disclosure, wherein the AMOLED pixel circuit comprises: a light-emitting module 11, a touch control module 12, a control module 13, an output module 14 and a driving and amplifying module 15.
