WARNING
This purchase is of the 5x PCB BOARD TD-120 only. You will need to buy the LG240644 display at Aliexpress.
Shelf life:
As any factory and industry, whether cars or electronic equipment, every product has a specific time of manufacture and parts for maintenance.
Afterwards, this manufacture stops and starts to give way to new products, better with more quality and more efficient.
A great module:
The sound quality of the TD-12 and TD-20 modules are fantastic, and we realized this need to recover this great Roland product. So we bought two defective lcd modules, a TD-12 module, a TD-20 and then an expansion board to turn the TD-20 into a TD-20X.
Because the expansion brutally changes its operating program and we wanted to make sure that our product would be 100% compatible with all models.
With the arrival and testing of the modules, REVERSE ENGINEERING was started, that is, the whole process took several months, between reading the protocol and analyzing how it forms the screen. Once this protocol was completed, research began to solve the speed problem. Because in addition to having the speed of Roland’s protocol, it would still have the protocol and display speed that replaces it. To solve this timing and protocols fight we have a microcontroller in the middle of the road that does all the heavy lifting.
Once the reverse engineering was completed and the program made for its conversion to a new lcd, with that our generic Display the TD-120 was born.
We tested it on 3 models and it proved to be 100% compatible with the original Display protocol. Of course, as it is not original, we have a processing time to convert Roland’s protocol to a new graphic display, so depending on the function it may sometimes present a small latency or delay, but this does not compromise or affect its operation.
As it is an electronic product, we always think about user safety.
As Roland’s original Display is 5V, we opted for a 3V3 Display. In other words, we have an excellent resistive isolation between the module board and the board of our new DisplayTD-120.
With this isolation from the voltage conversion, we work 100% isolated from the Roland processor. And we can be sure that if any electronic problem happens, the probability of it being our Display is extremely low.
And our confidence in our product allows us to give 6 months warranty on our DisplayTD-120.
The manufacture:
All manufacturing is already being done in China by Zhuhai Kameda Technology Co., Ltd.
In other words, we have the latest technology in electronic assembly.
Guarantee
Our warranty is 6 months.
We do not guarantee in case of breakage or any kind of damage to the TD-120 Board during installation.
