METHOD, DEVICE AND SYSTEM FOR DETERMINING LIGHT-LEAKAGE DEGREE OF DISPLAY PANEL AND TEST FIXTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17628809 titled 'METHOD, DEVICE AND SYSTEM FOR DETERMINING LIGHT-LEAKAGE DEGREE OF DISPLAY PANEL AND TEST FIXTURE

Simplified Explanation

The present disclosure describes a method, apparatus, and system for determining the degree of light leakage in a display panel. It also introduces a test fixture for this purpose. This technology is relevant to the field of display technologies.

  • The method involves using a light-leakage detection device to detect sub-regions of the display panel.
  • If the detection device identifies at least one sub-region with light leakage, it calculates the light-leakage degree based on the average brightness values of the sub-regions and the brightness value of the light-leakage sub-region.
  • This automated method improves the reliability and accuracy of determining the light-leakage degree compared to manual inspection by an inspector.

Potential Applications

This technology can be applied in various industries and sectors, including:

  • Display manufacturing: The method can be used during the production process to ensure the quality of display panels by detecting and quantifying light leakage.
  • Quality control: It can be employed as part of quality control procedures to assess the performance of display panels before they are shipped to customers.
  • Consumer electronics: Manufacturers of smartphones, tablets, laptops, and other devices with display panels can use this technology to ensure that their products meet the desired standards.

Problems Solved

The technology addresses the following problems:

  • Manual inspection limitations: The traditional method of manually inspecting display panels for light leakage is subjective and prone to human error. This automated method eliminates these limitations and provides a more reliable and accurate assessment.
  • Time-consuming process: Manual inspection can be time-consuming, especially for large-scale production. This technology speeds up the process by automating the detection and measurement of light leakage.
  • Inconsistent results: Different inspectors may have varying interpretations of light leakage, leading to inconsistent results. This technology provides a standardized and objective approach to determining the light-leakage degree.

Benefits

The use of this technology offers several benefits:

  • Improved reliability: By automating the detection and measurement process, the technology reduces the reliance on human judgment, resulting in more consistent and reliable results.
  • Increased accuracy: The method calculates the light-leakage degree based on objective measurements, leading to more accurate assessments compared to subjective manual inspections.
  • Time and cost savings: The automated process is faster and more efficient than manual inspection, saving time and reducing labor costs in the production and quality control processes.


Original Abstract Submitted

The present disclosure provides a method, an apparatus and a system for determining a light-leakage degree of a display panel, and a test fixture, and relates to the field of display technologies. When a light-leakage detection device detected that the plurality of sub-regions includes at least one light-leakage sub-region, the light-leakage detection device can determine a light-leakage degree of the display panel based on an average of brightness values of the plurality of sub-regions and a brightness value of the light-leakage sub-region. Compared with a way that an inspector manually determines a light-leakage degree, the light-leakage detection device can automatically determine the light-leakage degree of the display panel based on brightness values of the sub-regions by the method according to the embodiment of the present disclosure, thereby effectively improving the reliability and accuracy of the light-leakage degree of the display panel as determined.
