POWER LINE DESIGN MODIFICATION TO MITIGATE VERTICAL BAND CROSSTALK: abstract simplified (17754830)

• This abstract for appeared for patent application number 17754830 Titled 'POWER LINE DESIGN MODIFICATION TO MITIGATE VERTICAL BAND CROSSTALK'

Simplified Explanation

This abstract discusses techniques to ensure a uniform level of brightness across a display, specifically an AMOLED display used in computing devices. The display may have a hole in the active area for a camera or button, which can cause uneven voltage distribution in the power supply mesh near the hole. The techniques described in this abstract involve using portions of the power supply mesh that are not connected to the voltage supply bus to maintain a consistent voltage drop across the entire active area of the display.

Original Abstract Submitted

Techniques to provide uniform luminance across a computing device display, such as an active matrix organic light emitting diode (AMOLED) display. In some examples, a computing device display may include a hole within the active area of the display that may be used for a camera, a button or some other function. The hole may result in a non-uniform voltage drop in a power supply mesh in regions of the active area near the hole. The power supply mesh may provide electrical energy to elements of the display. The techniques of this disclosure include portions of the power supply mesh that are not connected to the voltage supply bus to ensure a uniform voltage drop across the active area of the display.
