Screen tints, whether they are green or pink, can be a frustrating problem for cell phone users. These tints affect the overall visual experience by distorting colours on the display. However, with proper cell phone display calibration, it is possible to fix these screen tints and restore accurate colours to the screen. In this article, we will explore what screen tinting is, the reasons behind it, and methods to fix it. Whether you are dealing with a green tint or pink tint on your cell phone’s display, this article will provide valuable insights and solutions.

What Is Screen Tinting?

Screen tinting, whether it is green tinting or pink tinting, refers to a hue that develops on an AMOLED display when the smartphone is under 15-20% brightness. This tinting is not spread uniformly across the entire screen but is more evident in specific sections.

The process of color calibrating the display involves the deposition of RGB emitting layers on each white pixel of the display using a color mask stencil. If this mask is disturbed or not placed accurately during deposition, it can result in non-uniform color output on the display.

Screen tinting can be a visible issue but is not majorly problematic for most users.

Understanding Screen Tinting

Screen tinting occurs on AMOLED displays, which are commonly used in smartphones. When the display brightness is set to a low level, typically under 15-20%, a green or pink tint becomes noticeable. This tint is not evenly distributed across the entire screen but appears in specific areas.

The root cause of screen tinting is the color calibration process during manufacturing. To achieve accurate colors, RGB emitting layers are deposited on each white pixel of the display using a color mask stencil. If the mask is disturbed or misplaced during deposition, it can lead to uneven color distribution on the screen.

While screen tinting can be visually apparent, it is not a significant problem for most users. It primarily affects the display’s hue in specific lighting conditions and brightness settings.

Impact of Screen Tinting

The effects of screen tinting are more noticeable in display quality enthusiasts and individuals with a keen eye for color accuracy. However, for the average user, the issue may go unnoticed or have minimal impact on overall smartphone usage. Only under specific circumstances and viewing conditions does screen tinting become apparent.

Reasons for Screen Tinting

Screen tinting, an issue that can affect OLED displays, is primarily caused by the deposition process used during color calibration. This process involves the deposition of RGB emitting layers on each white pixel of the display, which is achieved using a color mask stencil.

If the color mask stencil is disturbed or not placed accurately during the deposition process, it can result in errors in the spacing of the color deposits. Consequently, this leads to non-uniform color output on the display, resulting in the appearance of screen tinting.

This issue is more likely to occur during the manufacturing process, particularly on defective units. While screen tinting is not a major concern for most users, it can become visible under specific lighting and brightness conditions.

To help illustrate the process, the following table provides an overview of the color calibration process, highlighting the deposition of RGB emitting layers and the role of the color mask stencil:

While the color calibration process is generally effective, screen tinting can occur when there are inaccuracies in the deposition process or the color mask stencil. It’s important to note that for most users, screen tinting is a minor issue and is only noticeable in specific conditions.
