Slot Machine Display Panel with PDLC Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic reel game machines are limited to only providing a single reel game, making it difficult for gamers to play other games without separate machines, which increases installation area and cost.
Innovation Solution
A display panel structure incorporating a liquid crystal display (LCD) panel, polymer dispersed liquid crystal (PDLC) films, and reflective plates, allowing for selective light blocking and enabling the play of both reel and display-based games on a single machine by controlling light transmission with an electric field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single reel game machine is used, then the installation area and cost are reduced, but the gamer cannot play other games besides the reel game
Solution Approach 1:
The display panel is designed to perform multiple functions: it can display reel game symbols when light is transmitted, and display other game content when light is blocked. This allows a single machine to provide both reel games and other display-based games, increasing game variety without requiring additional installation area
2Adaptability or versatility
If separate game machines are installed for different games, then the gamer can play various games, but the installation area and cost increase
Solution Approach 1:
The patent combines the reel game display function and the other game display function into a single display panel system. By integrating both game types into one machine with a unified display interface, the system complexity is reduced compared to having separate machines, while still providing game variety
3Adaptability or versatility
If prisms, diffusers, light guides with apertures are used in the display panel, then the reel game can be displayed, but it becomes difficult to display other games and the structure becomes complex
Solution Approach 1:
The patent removes complex optical components such as prisms, diffusers, and light guides with apertures from the display panel structure. Instead, it uses a simpler configuration with an electronic shutter that can block light to enable display of other games, thereby reducing structural complexity while maintaining display flexibility
4Adaptability or versatility
If an electronic shutter is added to block light for displaying other games, then other games can be displayed, but the device complexity increases
Solution Approach 1:
The electronic shutter is integrated into the existing display panel structure, combining the light-blocking function with the display system. This unified approach allows game switching capability to be added without proportionally increasing overall device complexity, as the shutter becomes part of the single machine's integrated system
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
Enables gamers to play various games on a single machine, reducing installation area and cost by eliminating the need for separate game machines and simplifying the display panel structure.
Implementation Method 1
a first polymer dispersed liquid crystal ("PDLC") film disposed behind the LCD panel; reflective plates spaced from the first PDLC film, fixed to a rear side of the frame, and disposed in the frame

AI summary
There is provided a light-transmitting structure of a display panel for a slot machine using an electronic reel game scheme that is capable of playing other games on a reel game. The structure is located behind a touch pad. The structure allows a gamer to selectively play a typical display-based game through a separate game program while playing the reel game.
