Multi-layers

Sometimes, one design can be separated to two parts for simplifying the operation. For example in LCD light guide plate, LED light source area can be separated and defined the density profile independently. Or you may have many ideas for one product, but it is high cost to make true for each idea. BacklightFly can make your all ideas true in one design file. Below, we used the simple case to guide you how to set up a multi-layer design.

You will define the size when you create a new design. Then, BacklighFly will create a layer, named as main, automatically, and the size is same with the new design you created. You can modify the style of main layer in properties window directly, including re-sizing, re-naming, and re-locating.

1. Create new design

2. Modify the style of main layer

Click "New design", select "New layer", and you can set up a new layer. Eventually, a design with multi-layer is created. The modification of each layer is independent.

On the borderline between layers, you may find the sharp density change. That can be improved by select right composite mode.

Example 1 : DOE for comparison between different density profile

If more than one density profile can be combined in one design file, that will help you to save cost in the preliminary DOE stage. Only one output is made as product, but you can get  all required information. Below figure shows you that two density profiles were output in one light guide plate, and that can help you to choose the better one.

Example 2 : design LED light source area independently

The density profile on LED source area is much complex than other region. Separating LED source area can simplify the design procedure. Create two layers: one for main area and one for LED source area.

For main area, you can use the simplest design line to create the density profile. For LED source area, you just need to re-locate the design lines to match LED positions and you can adjust for each LED site. The adjustment for LED source area will not affect the density profile on main area.
