Displays in general are a massive PITA to work with, even as an OEM it&#;s like pulling teeth trying to documentation on any given screen, that&#;s not a joke it is easier to get access to the pinout of Intel Celeron and Atom processors than it is to get a meaningful datasheet from a display vendor.

There&#;s a lot of issues at hand and it&#;s not safe to just swap in a random display, you can damage the display you&#;re installing and you can also damage the main board. It might use an ePD connector, but that doesn&#;t mean the pinout or voltage is the same. Mobile device connection ports are not standardized like computer monitors are. You have a few different protocols, of course such as LVDS, ePD, etc. Even if you managed by miracle to find a screen with the exact same voltages and pinouts as the official screen, unless they have already integrated a touch controller into the board, it&#;s not going to work.
And this isn&#;t even getting into the fact that both LVDS and ePD screens often utilize the same connectors but are completely incompatible with one another and there&#;s no real way to tell just by counting the number of pins or the connector type.
Realistically, this is something that would require frame.work to design into their mainboard. It is possible to reverse engineer the screen, but that&#;s going to be fairly expensive and time consuming while a more affordable alternative would be simply adding a digitizer to the existing screen.
To do that you are going to need make a touch controller as well which isn&#;t particularly difficult, you could probably just use an STM32 micro controller and connect it to a USB port.
As much as I would love to take you up on that gofundme offer, just buy a touch overlay (which is just a pre-made version of what I described) and slap it on your existing screen:
A lot of our business is based on bespoke solutions, simply from supplying a custom cable to a complete new finished monitor.
We are ISO approved so all monitor designs and custom touch screens are controlled through drawing revision, customer sign off and PCN where necessary.
Longevity of supply is key and we endeavour to design a custom touch screen using components with a good continuity of supply. If something should go obsolete we would be able to upgrade with no or minimal disruption to the monitor design, we look for form-fit-function capability.
One of our biggest strengths is rapid prototyping for bespoke finished and open frame chassis'. We have a selection of standard POSLine Displays but if one of these is not suitable we will look at mechanical brief and engineer a solution. Whether it be another product which needs upgrading, or a new monitor design, we will design a custom touch screen solution aiming to tick all the boxes. Once the touch screen design is complete and approved, if required we can certify the product to the appropriate standard e.g. CE testing

Within the group we have developed our own in-house Prisma range of AD cards, Industrial media players and LED backlight drivers. We control the design of all our custom touch screens so we are able to modify, adapt or re-work very quickly to enable new functions.
Includes preloading the SBC's with an image - we have the mass programming tools to burn images on SSD and HDD. Our ISO and use of SAP ensures that we have full traceability. We allocate kits with unique parts, eliminating the risk of forgetting to order materials. We aim to always get it right.
We often see customers who need the Prisma to perform certain functions e.g. fixed colour settings or timing to support legacy CRT displays. By modifying the firmware we can give each customer the functions they need.
We can fit touch screens to LCD's in our clean room environment. This means the customer does not have to take the risk as we can fit the custom touch screen avoiding breakage, misalignment or contamination. Depending on the application and budget we can use our highly effective strip bonding method or optical bonding.
To maximise daylight readability and ruggedness we have invested highly in a European based optical bonding facility. This is the process of applying silicone between the front of the LCD and the touchscreen cover filter.
We have many years experience in exchanging standard backlights and filter stacks with enhanced performance components offering premium high brightness displays or bespoke backlights (i.e. night vision compatible backlights - NVIS).
Recently introduced is our infinity range of PCAP touchscreens, giving infinite options of touch. With no or small level of engineering (based on artwork) we can produce tablet edge to edge true flat glass touch screen designs which are shaped and branded. The tablet market has set a benchmark of what is expected from a touchscreen we are adding the finish needed. We now supply infinite touch to a range of markets including medical, gaming, vending and process control.
