Display Device Integrated Logo Module Bezel Thickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require a front bezel frame to mount logos, which hinders the development of borderless designs and increases bezel portion thickness, compromising aesthetics and user convenience.
Innovation Solution
A display device with an integrated logo module that omits the front bezel frame by using a transparent board with a light shielding portion and a light transmitting portion, where the logo module is placed on the rear surface to display a logo through the light transmitting portion, allowing for a bezel-less design while maintaining brand recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a front bezel frame is provided to mount a logo, then logo visibility and brand recognition are improved, but bezel portion thickness increases and borderless design is compromised
Solution Approach 1:
The logo module is repositioned from the front bezel frame to the rear surface of the transparent board, utilizing the depth dimension of the display device. This spatial relocation allows the logo to be displayed through the transparent board from the rear, eliminating the need for a front bezel frame while maintaining logo visibility.
Solution Approach 2:
The transparent board serves as an intermediary medium that allows light to pass through from the rear-mounted logo module to the front surface. This intermediary structure enables the logo to be displayed without requiring a front bezel frame, resolving the contradiction between logo visibility and bezel thickness.
2Adaptability or versatility
If a front bezel frame is omitted for borderless design, then design aesthetics and user convenience are improved, but logo mounting capability deteriorates
Solution Approach 1:
The logo mounting location is shifted from the front horizontal plane to the rear surface, utilizing the depth dimension. This allows borderless front design while maintaining logo mounting capability through the transparent board.
Solution Approach 2:
The logo is displayed by projecting light through the transparent board rather than physically mounting a logo on the front bezel. This optical copying approach maintains logo visibility without requiring front bezel infrastructure.
3Length of stationary object
If logo is displayed through light transmitting portion, then bezel portion thickness is minimized, but driver circuit unit arrangement becomes constrained
Solution Approach 1:
The transparent board is segmented into functionally distinct regions: a light transmitting portion for logo display and a light shielding portion for driver circuit unit arrangement. This segmentation allows both logo visibility and circuit integration without increasing bezel thickness.
Solution Approach 2:
Different regions of the transparent board are assigned different optical properties: the light transmitting portion allows logo visibility while the light shielding portion provides a backdrop for driver circuit units. This local differentiation resolves the contradiction between minimized bezel thickness and circuit arrangement complexity.

Implementation Method 1
a transparent board including a light shielding portion formed along an edge thereof to define the non-display area by blocking light
Implementation Method 2
a light transmitting portion formed by removing a part of the light shielding portion
Implementation Method 3
a logo module placed on a rear surface of the transparent board so as to overlap the light transmitting portion, the logo module outwardly displaying a logo through the light transmitting portion

AI summary
A display device including a display panel having an image display area and a non-display area, a driver circuit unit to feed an image formation driving signal to the display panel and a controller is provided. The display panel includes a transparent board including a light shielding portion formed along an edge thereof to define the non-display area and a light transmitting portion formed at a part of the light shielding portion, a rear board placed to face the transparent board and a logo module placed on a rear surface of the transparent board to overlap the light transmitting portion to outwardly display a logo through the light transmitting portion. At least a part of the driver circuit unit is formed on one of the transparent board and the rear board so as to overlap the light shielding portion. The display device may minimize a lower bezel region.
