![]() As such, they may not be ideal in scenarios that require a lot of brightness. Edge lit frame light boxes provide a standard level of brightness. This is because the light that illuminates the graphics shines directly. Suppose you want your graphics to have high brightness, then backlit light boxes are the perfect option. The Brightness You Desire Your Graphic to Have Beyond that size, they need to be backlighted. It is also important to note that we don’t recommend edge lit illumination for sizes beyond 72” W x 120” H. All of these factors shape your display and how it will look when lit up. Choosing the best light box for your display usually comes down to budget as well as size of your working surface, how strong the light needs to be and how you want the light to hit and showcase the graphics inside. One of the top decisions in choosing your light box setup is the size of your display. They don’t consume a lot of energy and require minimum maintenance. Edge lit picture frame light boxes use indirect lighting. The main difference between an edge lit frame and a backlit light box is their mode of lighting. How to Choose Between an Edge Lit Light Box and a Backlit Light Box Many people prefer backlit signs due to their ability to light up large format graphics in the most even, harmonious way. Also, backlit light boxes don’t have the low profile build edge lit boxes have since they require more space behind the graphic (2-4 inches deep) for light diffusion purposes. One factor you should consider is that these light boxes require more bulbs compared to edge lit frames. ![]() This design allows backlit light boxes to be more visible and have an even distribution of light intensity across the entire frame. This framing style is characterized by LED lights all over its entire back panel, facing toward the graphic image. What Is a Backlit Light Box?īacklit light boxes are well-suited for large graphics illumination. Larger boxes usually have bulbs further away from the center. Keep in mind that the size of an edge lit light box determines how far the LED lights will be from the center. How big your light is also affects the diffusion of light towards the frame. This will help the light circulate throughout the whole display, and avoid those dark spots and other types of lighting gaps. However, some edge lit light boxes are made with a diffusion grid that is placed between the LEDs and the graphic. With this lighting approach, there may be a slight glow on the corners and sides of your display. Edgelit LED Light Boxes are usually more cost-effective light boxes, as they require fewer LED light strips for complete illumination. This is because the lights positioned on the side of the boxes make it possible to design an ultra-thin frame. As a result, LCD TVs with local dimming can produce deep, uniform blacks and have a better contrast ratio than the LCD TVs that don’t have this feature.Edge lit light boxes are typically very thin. So the TV can turn off LED backlighting in parts of the screen where it’s supposed to be darker while keeping other parts lit. It allows TVs to control the backlight on a scene-by-scene basis. The LED backlight zones in full array and edge-lit TVs are significant as they enable the manufacturers to implement a feature called local dimming. But unlike both direct-lit and full-array TVs, edge-lit TVs have LEDs on the perimeter, and depending on the TV, these LEDs may or may not be grouped into multiple zones. Full-array TVs have a similar LED placement, but the number of LEDs is significantly more, and these LEDs are divided into different zones. As the name suggests, direct-lit TVs feature a panel of LEDs placed directly behind the display stack. LCD TVs can be grouped into three categories based on the type of LED backlighting system: Direct-lit, edge-lit, and full-array.
