DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094769 titled 'DISPLAY DEVICE

Simplified Explanation

The display device described in the abstract includes a display panel with two active areas that can slide in a specific direction, supported by segments and a guide rail in a panel housing. A first roller in the panel housing helps facilitate the sliding motion of the display panel.

• Segmented display panel with sliding capability:

 - The display panel has two active areas that can slide in a specific direction.
 - Segments spaced apart from each other support the lower surface of the sliding active area.
 - A guide rail in the panel housing engages with the segments to guide the sliding motion.

• First roller for facilitating sliding motion:

 - The first roller extends in the direction of sliding and is surrounded by the lower surface of the sliding active area.
 - It has a central portion with a specific diameter and a stepped portion protruding from it, forming a level difference.
 - The stepped portion overlaps with at least one of the segments to create a space for smooth sliding.

Potential Applications

The technology described could be applied in: - Sliding display panels for mobile devices or tablets. - Interactive digital signage with movable display areas.

Problems Solved

This technology helps in: - Providing a mechanism for smooth sliding motion of display panels. - Enhancing user experience with interactive displays.

Benefits

The benefits of this technology include: - Improved functionality of display devices. - Enhanced user interaction with sliding display panels.

Potential Commercial Applications

The potential commercial applications of this technology could be in: - Consumer electronics industry for mobile devices. - Digital signage solutions for retail or public spaces.

Possible Prior Art

One possible prior art for this technology could be: - Sliding mechanisms in retractable screens or doors.

Unanswered Questions

How does the stepped portion of the first roller contribute to the sliding motion of the display panel?

The stepped portion of the first roller creates a level difference that overlaps with the segments, potentially reducing friction and allowing for smoother sliding. This aspect could be further explored in terms of its impact on the overall performance of the display device.

Are there any specific design considerations for implementing this sliding mechanism in different types of display panels?

It would be interesting to investigate if there are specific design considerations or limitations when applying this sliding mechanism to various sizes or types of display panels, such as OLED screens or flexible displays. This could provide insights into the versatility and adaptability of the technology across different display devices.

Original Abstract Submitted

a display device includes a display panel including a first active area and a second active area slidable in a first direction, a plurality of segments spaced apart from one another in the first direction, extending in a second direction intersecting the first direction, and supporting a lower surface of the second active area, a panel housing having a guide rail engaged with a portion of each of the segments to guide a sliding motion of the display panel, and a first roller extending in the second direction, disposed in the panel housing, and surrounded by the lower surface of the second active area. the first roller includes a central portion having a first diameter, and a stepped portion protruding from the central portion in the second direction, forming a level difference with the central portion, and overlapping at least one of the segments to form a space.
