Display Color Temperature Adjustment for Analog Picture Frame Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, when used as electronic picture frames, fail to mimic the texture and color of real picture frames due to their electronic nature and resistance to external light conditions, leading to a disconnect in user experience.
Innovation Solution
A display device equipped with a sensor module to detect external light color temperature and a processor that adjusts the color temperature of displayed still images to match the ambient light, creating a more analog-like experience by simulating the appearance of images on paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is used as an electronic picture frame with conventional display technology, then the device can display still images, but the screen provides a strong electronic product feel that resists user acceptance for analog sensibility
Solution Approach 1:
The patent changes the color temperature parameter of the displayed image dynamically based on the color temperature of external incident light. The processor adjusts the color temperature of the still image to match the ambient light conditions, making the display adapt to environmental parameters rather than maintaining fixed electronic characteristics.
Solution Approach 2:
The patent converts the harmful effect of external light (which normally causes color shifts and reduces image accuracy) into a beneficial feature by using the external light's color temperature as a reference to adjust the display output. Instead of resisting external light influence, the system embraces it to achieve more natural appearance.
2Reliability
If the display device relies on backlight and display panel as a light emitting device, then the device can function as a display, but the device is not greatly affected by color temperature of incident light from outside
Solution Approach 1:
The patent introduces dynamic adjustment of display parameters based on real-time sensing of external light conditions. The processor continuously monitors the color temperature of incident light and dynamically adjusts the color temperature of displayed images accordingly, transforming the static light-emitting display into an adaptive system.
Solution Approach 2:
The patent implements a feedback mechanism where the sensor module detects external light color temperature and feeds this information to the processor, which then adjusts the display output. This closed-loop control system enables the display to respond to and adapt to external environmental conditions.
3Stability of the object's composition
If the display device outputs images with fixed color temperature, then the device maintains consistent electronic display characteristics, but the picture frame cannot help having a difference from a real picture frame in terms of texture and color
Solution Approach 1:
The patent changes the color temperature parameter of displayed images based on external light conditions, allowing the display to mimic the behavior of real pictures that are naturally affected by ambient lighting. This parameter adjustment bridges the gap between electronic stability and natural realism.
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 display device effectively reduces the electronic feel, making it resemble a real picture frame by dynamically adjusting image color temperature and brightness to match external light conditions, enhancing user experience and reducing power consumption.
Implementation Method 1
a sensor module which senses a color temperature of light incident to the sensor module from an outside of the display device
Implementation Method 2
adjusts a color temperature of the still image based on the color temperature sensed by using the sensor module in outputting the still image

AI summary
A display device includes a display, a sensor module which senses a color temperature of light incident to the sensor module from an outside of the display device, and a processor electrically connected to the display and the sensor module. The processor operates in a first mode or a second mode or is turned off, depending on a user input, outputs a moving picture to the display in the first mode, outputs a still image to the display if detecting a user, turns off the display if failing to detect the user, in the second mode, adjusts a color temperature of the still image based on the color temperature sensed by using the sensor module in outputting the still image, and outputs the still image having the adjusted color temperature to the display.
