Embodiment 1

[0042] Such as figure 1As shown, this embodiment provides a pixel unit, including: a switching transistor T1, a driving transistor, a storage capacitor C1, an organic electroluminescent diode OLED, and a switching control unit 1; wherein, the first pole of the switching transistor T1 is connected to the data line Data, the second pole is connected to the switch control unit 1, the control pole is connected to the scanning line Gate L; the first pole of the driving transistor is connected to the first power supply terminal Vdd and the second terminal of the storage capacitor C1, and the second pole is connected to the organic electroluminescent diode OLED The first pole of the first pole, the control pole is connected to the second end of the storage capacitor C1 and the switch control unit 1; the second pole of the organic electroluminescent diode OLED is connected to the second power supply terminal Vss; the switch control unit 1 is connected to the switch control line Gate R,...

Embodiment 2

[0050] This embodiment provides a display panel, including the pixel unit in Embodiment 1.

[0051] Since the display panel in this embodiment includes the pixel unit in Embodiment 1, and a switch control unit 1 is added to the pixel unit in Embodiment 1, when performing row-by-row scanning line Gate L, the switch control line Gate Under the control of the control signal input on R, the control switch control unit 1 is turned on or off, thereby controlling whether the data voltage signal written on the data line Data can be written into the organic electroluminescent diode OLED. That is, the switch control unit 1 controls whether the pixel units in the display panel can be written with data voltage, so as to realize intelligent display according to the display requirements of the display panel.

[0052] Correspondingly, this embodiment also provides a display method of a display panel, which includes: a step of driving pixel units to display.

[0053] Specifically, a working ...

Embodiment 3

[0055] Such as figure 2 and 3 As shown, this embodiment provides a display panel, which is divided into a plurality of display areas arranged in an array, and each display area is provided with a plurality of pixel units in Embodiment 1. Wherein, the switch control units in the plurality of pixel units located in the same display area are connected to the same switch control line Gate R. That is, the pixel units in the same display area are controlled by a switch control line Gate R.

[0056] Specifically, when the scanning line Gate L on the display panel is scanned row by row, which switch control line Gate R is written into the working level signal, and which pixel unit in the display area can be written through the data line Data The data voltage signal, therefore, it is possible to selectively write the data voltage to the pixel units in at least part of the display area of ​​the display panel, so that the number of times the pixel units in each display area are writte...

Two terminals, the second pole is connected to the first pole of the organic electroluminescent diode, the control pole is connected to the second terminal of the storage capacitor and the switch control unit; the second pole of the organic electroluminescent diode is connected to the second power supply terminal; the switch control unit is connected to The switch control line is used to turn on or off under the control of the control signal input on the switch control line, so as to control whether the data voltage signal written on the data line can be written into the organic electroluminescence diode.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a pixel unit, a driving method, a display panel, a display method, and a display device. Background technique [0002] With the advancement of display technology, users have higher and higher requirements on the quality of images displayed by display devices. Generally, the higher the picture quality of the display device (that is, the clearer the picture), the higher the screen refresh rate. However, a high screen refresh rate will inevitably lead to an increase in power consumption. [0003] Therefore, high-quality images and low power consumption are a contradiction to be resolved in the display field. The traditional approach often takes care of one thing at the expense of another, or pursues high picture quality and generates greater power consumption; or sacrifices picture quality in order to reduce power consumption. There is rarely a good way to do both. ...
