Apply in scheme, OLED display pixel may include spontaneous emission luminous component, this spontaneous emission luminous component is based at least partially on confession
Launching light should be carried out to the value of the electric current of storage.For example, with source current value increase, display picture element bright
Degree also increases.On the other hand, the value with source current reduces, and the brightness of display picture element also can reduce.
In addition, OLED display can flow to display picture element using switchgear (for example, thin film transistor (TFT)) to control
The value of source current.In some embodiments, OLED display can receive the expectation brightness for indication display pixel
View data, and this view data is applied to the grid of switchgear.In such embodiment, the electricity of view data
The width of pressure controllable switch device channel, this switchgear channel can be used for for source current being directed to luminous component.For example,
Value with view data increases, and the value of source current can increase.On the other hand, the value with view data reduces,
The value of source current can reduce.In this way, OLED display can be based at least partially on the view data receiving to adjust
The brightness of section display picture element.
However, the brightness of OLED display pixel is also possible to by the data wire of other factors such as display picture element and storage
Interaction impact between capacitor.More specifically, can generate between the data wire of display picture element and storage
Parasitic capacitance.This parasitic capacitance can generate the brightness flop that can be perceived as visual artefacts.
Therefore, as will be described in more detail, the techniques described herein and equipment pass through to reduce in display picture element
The probability of parasitic capacitance or mitigate parasitic capacitance with the generation reducing visual artifact to help improve display display
Picture quality, and the probability that display can perceive visual artefacts can be reduced.
