Backlight Module Lighting Effects via Cover Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices for mobile devices face increased manufacturing costs and power consumption due to the need for additional light emitting components beyond the backlight module, which complicates the design of light, thin, and narrow border designs.
Innovation Solution
A display device design that utilizes a backlight module with a light source providing both primary light for the display panel and secondary light beams through slots in a cover to achieve additional lighting effects at a front panel, eliminating the need for additional light emitting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional light emitting components are added to provide lighting effects, then lighting functionality is improved, but manufacturing cost and power consumption increase
Solution Approach 1:
The backlight module's light source is designed to serve dual purposes: providing light for the display panel through the light guide plate, and providing additional lighting effects through light beams that pass through slots in the cover to illuminate the front panel. This multi-functional design eliminates the need for separate light emitting components, thereby reducing power consumption and manufacturing cost while maintaining lighting functionality.
Solution Approach 2:
The patent combines the display lighting function and the additional lighting effect function into a single backlight module. The light source, cover, and light guide plate work together as an integrated system where the same light source provides both functions, merging what would traditionally require separate components into one unified structure.

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
This solution reduces manufacturing costs and power consumption while enabling additional lighting effects for call alerts, exterior decorations, and virtual keys without compromising the thin and narrow border design.
Implementation Method 1
The first light beam enters the light guide plate from the light incident surface and is illuminated towards the display panel from the light emitting surface after being transmitted in the light guide plate
Implementation Method 2
The second light beam passes through the slot to be transmitted towards the light penetration region and is illuminated out of the containing space from the light penetration region
Data Source
AI summary
A display includes a casing, a display panel, a backlight module, a front panel and a cover. The casing has a containing space. The display panel is disposed in the containing space. The backlight module is disposed in the containing space and includes a light guide plate and a light source. The light source is adapted to provide a first light beam and a second light beam. The first light beam enters the light guide plate and is illuminated toward the display panel after being transmitted in the light guide plate. The front panel covers the containing space and has a light penetration region. The cover wraps the light source and has at least a slot. The second light beam passes through the slot to be transmitted toward the light penetration region, and is illuminated out of the containing space from the light penetration region.
