This is an introduction to our LCD (Liquid Crystal Display) products. Below, you will
find an explanation of these products, as well as the reasoning behind them. For those of you who are familiar with the differences between Parallel and Serial LCD modules, you may want to browse this page quickly, or skip it altogether and go straight to our LCD Products page. Our products in this category include Parallel LCDs, Serial LCDs, a Serial LCD Controller PCB and a Serial LCD Controller IC. These products are geared towards hobbyists and electronics developers.  Parallel LCD Modules: Parallel LCD modules are the standard LCD types in the industry. They typically have 14 or 16 pins. They are also the least expensive type. They require at least six different lines (wires) connected to it to make it work (not including power, ground and contrast). This is not a problem; however, in certain instances, it is not ideal or realistic to implement a Parallel LCD in a device. Next, we will describe the Serial LCD Modules and, in the process, explain why it may not be ideal or realistic to implement Parallel LCD Modules. Here's the Parallel LCD Modules that we offer at this time.
Serial LCD Modules: Serial LCD modules are standard Parallel LCD modules, but with an additional Serial LCD Controller PCB soldered to the Parallel LCD terminals. This Serial LCD Controller PCB can be seen as a converter. It accepts a standard serial transmission from one single wire and converts it to the standard parallel signal, using the six lines that were described above. Therefore, a Serial LCD module is much easier for a hobbyiest to implement, since the serial data can come from a PC or one pin of a BASIC Stamp. While a BASIC Stamp should be able to interface to a standard Parallel LCD fine, it is more sometimes a little more complex. Additionally, it uses five more I/O pins of the BASIC Stamp. These five extra I/O pins can be a critical reason why you would use a Serial LCD Module, instead of a Parallel LCD Module. Similarly, an electronics developer may want to implement a Serial LCD Module for the same reasons. Again, these reasons are: a less complex hardware and software design, as well as the fact that five less I/O lines will be needed from the developer's microprocessor. That is five more I/O pins that the developer will have for use in other areas of the device, such as buttons, LEDs, buzzers, etc. This also means that a developer can use a smaller, less expensive microprocessor. Here's the Parallel LCD Modules that we offer at this time.
Serial LCD Controller PCB: So, what if you already have your own Parallel LCD Modules and simply need to convert them to Serial LCD Modules? No problem. You can simply purchase our Serial LCD Controller PCB and solder it to your Parallel LCD Modules. Please see the details for the LCD-SLCD1-PCB in our LCD Products page. Serial LCD Controller IC: What if you want to use your own Parallel LCD Modules and create your own Serial LCD Controller PCB, but don't want to get into the complexities of the firmware design of the Serial LCD Controller IC? No problem. You can simply purchase our Serial LCD Controller IC and create your own Serial LCD Controller PCB, using our Controller IC. Please see the details for the LCD-SLCD1-IC in our LCD Products page. NOTE: This product is not normally sold to the public. However, we may be able to accommodate you for larger or special orders. Please contact us for details. |
