Display Panel Sensor Unit Hinge Motion for Slim Bezel Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor unit drive devices in image display devices require a bezel protrusion that impairs the appearance due to the need for a large space for storing the sensor unit, especially when measuring positions close to the display surface, leading to increased bezel width and protrusion.
Innovation Solution
A sensor unit drive device that allows the sensor unit to be stored on the side surface of the display panel in a retracted position, switching to a detection position through rotational and bending movements without protruding the bezel, using a hinge structure and drive means to facilitate smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the sensor unit is stored within the bezel in a retracted position, then the bezel width and protrusion are reduced, but the sensor unit cannot be smoothly moved to measurement positions
Solution Approach 1:
The sensor unit is designed with dynamic movement capabilities through hinge structures that enable rotational and bending motions. This allows the sensor unit to transition smoothly between the retracted storage position within the bezel and the extended measurement position, resolving the contradiction between compact storage and operational smoothness.
Solution Approach 2:
The invention introduces multi-dimensional movement by combining rotational movement around a rotational axis with bending movement along a bending axis. This two-dimensional movement path enables the sensor unit to navigate from the retracted position to the measurement position without requiring simple linear protrusion, thus maintaining sleek bezel appearance while ensuring smooth operation.
2Adaptability or versatility
If a large sensor unit is used to measure positions close to the center of the display surface, then measurement coverage is improved, but the bezel protrusion and width increase significantly
Solution Approach 1:
The sensor unit is designed to nest within the bezel structure when in the retracted position. The hinge structure allows the sensor unit to be stored compactly inside the bezel, eliminating the need for permanent protrusion. When measurement is required, the sensor unit extends from the nested position, enabling large sensor units to be used without permanently increasing bezel width or protrusion.
Solution Approach 2:
The dynamic extension mechanism allows the sensor unit to transition from a compact nested state to an extended measurement state. This dynamic capability enables the use of larger sensor units for better measurement coverage while maintaining a sleek bezel appearance during non-measurement periods.
3Volume of stationary object
If the sensor unit is rotated between storage and measurement positions, then space for storing the sensor unit is provided, but the bezel must protrude and have increased width
Solution Approach 1:
Instead of simple rotational movement that requires radial space, the invention combines rotational movement with bending movement. This creates a two-stage motion path where the sensor unit first rotates to align with the measurement direction, then bends to extend toward the display surface. This dimensional approach allows storage within the bezel without requiring the bezel to protrude or increase in width.
Solution Approach 2:
The movement mechanism is segmented into two independent hinge structures: one for rotational movement and one for bending movement. This segmentation allows each hinge to handle a specific aspect of the motion, enabling the sensor unit to achieve both storage compactness and measurement accessibility without increasing bezel dimensions.

AI summary
A sensor unit drive device, including: a sensor unit having a sensor; and a drive mechanism connected to the sensor unit and driving the sensor unit. The sensor measures optical characteristics of a display panel that includes a display surface that displays an image, the sensor unit is provided on a side surface of the display panel in a retracted position, and is configured such that the sensor faces the display surface in a detection position, the sensor unit moves so that the retracted position and the detection position can be switched when the drive mechanism drives the sensor unit, and the sensor unit moves to the detection position by a rotational movement of rotating around a rotational axis non-perpendicular to the display surface from the retracted position and a bending movement of bending toward the display surface via a hinge structure, when the drive mechanism drives the sensor unit.
