Get the final app updates for the world's first Lightfield tablet.
The original Lume Pad came out in 2020, and was a non-tracked "4V" device (4x4 views for a total of 16 views) glasses-free 3D Android tablet. After running the Leia Appstore for Lume Pad (2020) for four years, we're stopping support in July 2024, two years after we stopped selling the device. For your convenience, we will be providing download links to the final versions of Leia apps on Lume Pad (2020), and links to a few other popular apps, with no warranty or support, either express or implied. You will be using these apps at your own risk.
All links to Lume Pad app APKs are available at the bottom of this page.
Lume Pad is the world’s first Lightfield tablet. A crisp, comfortable 10.8-inch Lightfield display offering a no-compromise experience for the Android apps you know and love as well as a suite of apps that you can see in stereoscopic 3D with the naked eye without ANY specialized eyewear required.
If you’re a creator that wants to see your content in a new light, Lume Pad provides a beautiful medium to highlight your work.
Whether you’re designing buildings, developing games, creating 3D models in new ways, or even if you’re constructing a new take on medical visualization software: the Lume Pad is the tool for you. Pictures, videos, and 3D models. All elevated to the next level with Lightfield.
It all starts here with the Lume Pad and its powerful Leia app suite.
This guide will help you understand everything you can do with your Lume Pad.
The Lume Pad is a high-quality Android tablet with a chassis made of brushed aluminum. On the back of the device you'll find the Lume Pad and LitByLeia logos, the high-quality 3D camera, and the antenna window.
On the front of the device you'll find the front-facing camera, the ToF sensor, and of course, the DLB Lightfield display.
On the right side of the device you'll find the volume rocker and the lock button, and on the top of the device you'll find the USB-C charging port.
At Leia, we’ve developed a single optical layer sculpted by nanotechnology that sits just underneath the LCD display to create the Lightfield effect, powered by what we call Diffractive Lightfield Backlighting (DLB).
With 2D content, the Lume Pad’s 10.8-inch screen projects out a bright 2560X1600 picture. When used for traditional Android apps, that 16:10 screen looks bright, sharp and, well, like a normal high-end Android tablet.
But when the DLB is activated, lights pass through it to create a dynamic Lightfield 3D effect. The light projects out four views simultaneously in 16 directions -- this is Lume Pad's Lightfield view mode. Unlike other 3D solutions, Lume Pad is brighter, thinner, can instantly switch between full-quality 2D and Lightfield 3D, and can be rotated to support every orientation while in 3D. Lume Pad is LitByLeia.
Our goal is to deliver our vision of how Lightfield can change the way we see art, engage in commerce, and affect the world.
If you want more of a breakdown of how Leia’s DLB technology works, check it out here.
LeiaLogin is a unified account system across Leia's Lightfield apps and select partner apps from the Leia appstore. It's required for Lume Link and LeiaPix.

Photos are saved in Leia Image Format, which can instantly be sent to non-LitByLeia devices where they'll be seen in standard 2D, or to another LitByLeia device where they can be edited or viewed. Videos are saved as a high quality 4K per eye SBS, so they can be easily edited on traditional NLE video editing software or viewed on legacy 3D devices.
LeiaViewer allows you to see 3D models in new lights, textures and with 3D that leaps off the screen. And, with Sketchfab integration, you have access to over 500,000 3D models and animations.

This page describes the options available when editing images in LeiaPlayer.
The Depth slider controls the disparity value of your image. As you move the slider up, you will perceive more depth
Disparity is the difference in image location of the same 3D point when projected under perspective to two different camera views
Perception of depth arises from the “disparity” of a given 3D point in your right and left retinal images
The Focus slider controls the convergence value of your image.
As you move the slider up, more objects in your image will appear to be popping out of the front of the screen
As you move the slider down, more objects in your image will appear to be moving backward behind the screen
The convergence value is the point at which the left and right eye images align, which sets the location of convergence at the screen plane
Objects in front of this point will appear to be in front of the screen and those behind will appear to be behind the screen
The bokeh slider controls the digital blur applied to background pixels that are located behind the convergence plane
If you move the convergence slider to the very top, there are no pixels considered as behind the convergence plane, and thus aren’t part of the background
Thus you won’t see any digital blur applied to those pixels, even if you move the Bokeh slider to the very top
If you feel the need to increase the depth of your image a considerable amount to the point where you start to see visual artifacts in the background, you can add some bokeh, as it will blur the background and help conceal the artifacts.
These are primarily straightforward chroma editors that you will see in any mobile photo editing app
This will increase the brightness of all shadows and highlights in your image
Your photo will look brighter overall as you move the slider up
This will increase the photo’s color intensity
The colors in your photo will look more intense as you move the slider up
Contrast is the range of difference between different tones in a photo
For black and white photos, contrast describes the difference between the darkest and lightest tones
For color photos, contrast applies to how sharply colors stand out from one another
As you move the slider up, bright colors will appear brighter
As you move the slider down, dark colors will appear darker
Adjusting the Hue slider to see shifts in the color values in your images
You can radically alter your photos colors
Smaller, more incremental adjustments can effectively reduce unwanted color casts and correct the photos white balance
Color Pop will remove color from pixels considered as part of the background
This makes the colors of objects in the foreground really standout
This is the only feature in the Color section that makes use of the disparity map
Simple tools for resizing and rotating your image.
Note that if you crop an image down to a smaller size, its disparity and convergence values will increase, which will increase the depth sensation
This is where the artistic flavor gets added
Tap any of the relighting presets, and you will have different lighting configurations added to your image.
These lighting placements use the depth map to get placed into different parts of the image.
After applying a preset and hitting the check button to confirm your changes, you can open the Relighting section again and add another preset. This will let you create custom presets by combining multiple presets together. If you keep adding them, your pictures will start to take on a very different tone.
Apply styles to your images by selecting the preset filters.
As with relighting, you can apply multiple presets to each image to create your own custom styles.
Combine these filters with a bunch of relighting presets to make each image a unique work of art
