Display Screen Transmittance Design for Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The extension of display area in mobile terminals to achieve a full-screen effect is hindered by non-display elements such as front cameras, which cause uneven brightness due to blocking of the backlight source, resulting in darker side areas of the display screen.
Innovation Solution
A display screen design that includes a receiving space for non-display elements within the backlight module, with a first display area having greater transmittance than a second display area, allowing for improved brightness uniformity by adjusting the transmittance and pixel arrangement to accommodate these elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is extended to achieve full-screen effect, then the display coverage is improved, but the brightness uniformity deteriorates due to non-display elements blocking the backlight source
Solution Approach 1:
The patent applies local quality by differentiating the transmittance of the display panel into two distinct regions: a first display area with higher transmittance positioned away from the backlight source, and a second display area with lower transmittance positioned closer to the backlight source. This local differentiation compensates for the light blocking effect of non-display elements, ensuring uniform brightness across the entire display area while maintaining full-screen coverage.
2Adaptability or versatility
If non-display elements are placed in the display area, then the functional requirements are met, but the brightness of the display screen deteriorates due to light blocking
Solution Approach 1:
The patent positions non-display elements in the second display area with lower transmittance, creating a local quality differentiation that isolates the light-blocking effect to a specific region. This allows the first display area to maintain high brightness while the second display area accommodates non-display elements, thus satisfying functional requirements without compromising overall display brightness.
Solution Approach 2:
The patent segments the display panel into two distinct display areas with different transmittance characteristics. The first display area is optimized for brightness and is positioned away from the backlight source, while the second display area with lower transmittance is positioned closer to the backlight source to accommodate non-display elements. This segmentation allows each region to serve its specific function optimally.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively increases the display brightness of the first display area and maintains uniformity with the second display area, enhancing the overall brightness uniformity of the display screen.
Implementation Method 1
The transmittance of the first display area is greater than the transmittance of the second display area
Data Source
AI summary
The embodiments of the disclosure provide a display screen and a mobile terminal, and relate to a technical field of mobile terminals. The display screen may include a display panel and a backlight module. The backlight module may include a backlight panel and a backlight source disposed on one side of the backlight panel. Wherein, the display screen may define a receiving space at least through the backlight module and configured to receive a non-display element. The display panel may include a non-display area, a first display area and a second display area surrounding the non-display area and the first display area. The non-display area corresponds to the receiving space. The first display area is set on a side of the non-display area away from the backlight source. The transmittance of the first display area is greater than the transmittance of the second display area.
