ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is for a display system, and more particularly, pertains to a display system having maintenance accessibility and incorporating LED pixels, lenses, and louvers incorporated into one or more modular display panels to present an electronic display.
2. Description of the Prior Art
Prior art electronic display systems oftentimes lacked in brilliance and contrast. A solution to these deficiencies called for an increase in power to try to compensate for lack of brilliance or contrast, such solution often incurring extra required electrical energy, an economic drawback, and additional generation of heat. Along with larger electrical power requirements and heat generation came the need for more heavily constructed components, also an economic drawback. Prior art display systems also provided systems which had poor. access for maintenance in that accessibility was limited to one side of the system. Such accessibility required that numerous fasteners be removed for the separation of layered component members to gain access to components interior to the display. Clearly what is needed is a method of increasing brilliance, contrast and viewability without increasing cost, material size and electrical consumption while offering readily accessed components for maintenance or component replacement.
SUMMARY OF THE INVENTION
The general purpose of the present invention is to provide an improved outdoor display system.
According to embodiments of the present invention, there is provided a display system, which can be used for indoor or outdoor applications, including one or more modular display panels in which a circuit board having a matrix of various colored LED pixels is mounted in a housing. Also included in the modular display panels are lenses which align over and secure over and about the colored LED pixels to direct, focus, refract or otherwise alter light emitted from the LED pixels for suitable enhanced viewing. Horizontally aligned louvers are interspersed with the LED pixels and lenses to shade the LED pixels and lenses from ambient light, thereby improving the view contrast and viewability. Each modular display panel secures to one or more module support members by quick connect latches. A driver board and a power supply also secure to the modular display panel by twist-on fasteners. Accessibility is provided to both sides of the display system by the use of the quick connect latches, which can be actuated form the front or rear for removal of the housing and attached members, and by readily removable circuit boards and louver panels.
One significant aspect and feature of the present invention is a display system which includes modular display panels.
Another significant aspect and feature of the present invention is a display system having a pixel lens aligned to an LED pixel to increase display brilliance and viewability.
A further significant aspect and feature of the present invention is the use of louvers to shield the LED pixel and lenses from ambient light, thereby increasing the display contrast.
Another significant aspect and feature of the present invention is the use of one or more support members which accept latch mounted components such as a modular display panel having a housing, a driver board, a power supply, and a printed circuit board having LED's, lenses and louvers.
Another significant aspect and feature of the present invention is the use of PC boards and louver panels secured to the front of a housing which quickly and readily mounts.
Yet another significant aspect and feature of the. present invention is a latch system incorporated in a modular display panel which is accessible at the front and back of the modular display panel.
Having thus described embodiments of the present invention, it is the principal object of the present invention to provide a display system having sufficient brilliance and contrast and which is easily accessed and maintained.
