Solution Overview
Problem
The integration of additional structures such as lighting in organic light-emitting diode (OLED) displays requires additional manufacturing processes, increasing processing time and costs, and poses challenges in space utilization due to limited space.
Innovation Solution
A display device design that includes a separate lighting part outside the data display area with a switch-controlled high-potential power supply line, allowing the lighting part to be activated independently of the system power, using a display panel driver and a lighting driver to manage organic light-emitting diodes in both the data display and lighting areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional structures such as lighting are integrated into OLED displays, then lighting functionality is provided, but processing time and manufacturing costs increase
Solution Approach 1:
The patent merges the lighting part with the display panel by forming both the display pixels and lighting elements using the same OLED fabrication process. The lighting part is integrated into the non-display area of the substrate, allowing simultaneous manufacturing of display and lighting functions without requiring separate production lines or additional processing steps.
Solution Approach 2:
The OLED structure serves dual purposes: it functions as both the light-emitting display pixels and the lighting part. By using the same organic light-emitting diodes for both display and ambient lighting purposes, the system achieves multi-functionality from a single manufacturing process, eliminating the need for separate lighting component production.
2Adaptability or versatility
If additional structures such as lighting are integrated into OLED displays, then lighting functionality is provided, but manufacturing costs increase
Solution Approach 1:
The patent combines the manufacturing of display pixels and lighting elements into a single OLED fabrication process. By forming both structures simultaneously on the same substrate using identical material deposition and patterning techniques, the patent eliminates the need for separate manufacturing operations, thereby reducing overall manufacturing costs.
Solution Approach 2:
The patent uses homogeneous manufacturing approaches where the same organic layers, electrodes, and encapsulation structures serve both display and lighting functions. This uniformity in material selection and processing methods simplifies the manufacturing workflow and reduces costs associated with managing multiple production processes.
3Adaptability or versatility
If additional structures such as lighting are integrated into OLED displays, then lighting functionality is provided, but space utilization becomes challenging
Solution Approach 1:
The patent divides the substrate into distinct functional zones: a display area containing pixels and a non-display area containing the lighting part. This spatial segmentation allows the lighting elements to be positioned in the peripheral region, effectively utilizing available space without interfering with the active display area.
Solution Approach 2:
The patent utilizes the two-dimensional substrate surface by placing the lighting part in the non-display area, effectively using the peripheral dimension of the substrate. This approach maximizes space utilization by accommodating lighting functionality in the otherwise unused border regions surrounding the display area.

This design enhances space utilization, reduces manufacturing complexity and costs by eliminating the need for additional processing steps, and provides user-controlled lighting functionality even when system power is off.
Implementation Method 1
The OLED display reproduces input images based on a phenomenon in which electrons and holes recombine in the organic layers in the OLED of each pixel to emit light as current flows through a fluorescent or phosphorescent organic thin film
