YB1602A LCD Display Board is a 16x02 character in 2 lines, high quality, black background, and mono-color character (white, yellow, red, orange, green, or blue) display, which is controlled by SPLC780C display driver chip. It is a serial LCD display without pin header. The model number of 1602 means 16 columns (characters) multiply 02 rows, so this display can show 16 characters in each of the 2 rows, therefore a total of 32 characters can be displayed simultaneously. It needs 6 digital pins and 2 power pins for an LCD.

The module can easily be interfaced and communicated to an Arduino board and microcontroller through an I2C communication interface (IIC/I2C Serial Interface Adapter Module). Because of not having any pin header, the I2C (IIC) adapter is needed to solder on the display module, then through I2C interface communication is established. Just 2 lines are required to display the information on any Arduino based projects. It will save at least 4 digital/analog pins on the Arduino. All connectors are based on the XH2.54 standard (Breadboard type).

Its backlight can conveniently be changed by a jumper wire or through the program, Also, for adjusting the contrast of the screen display, a blue part screw is provided. It can be supplied with a logical level of 3.3V and 5V DC. This display is specialized for displaying letters, numbers, dot matrix, and symbols for Arduino projects, 3D printers, HMI projects, and so on.

In the not too distant past it was uncommon for an OEM, or manufacture to design and purchase a customized LCD display. The main reason was that the MOQs (Minimum Order Quantities) were very high, the tooling (NRE or Non-Recurring Engineering) was prohibitive and the lead times would stretch out for several weeks. This has changed drastically in the last four to five years. Many of these barriers and restrictions have been reduced.

In the last few years there have been many changes in custom LCD display technology. Many of these changes include new types of display technologies, new manufacturing process and increased efficiency in the display industry.

Custom Icons: There are many standard icons such as battery indicator, AM/PM and F/C. A customized Static display allows the customer to incorporate unique icons. We have supplied custom LCD displays that included icons of the company name or logo. Products that will be used outside of the United States offer icons specific to metric values such as mm, kg, celsius, as with other options on a custom segmented display. The number of icons does not affect the tooling cost. Each additional segment or icon has a very small increase on the total cost of the display.

Backlight Options: Standard and custom static displays do not contain a backlight. The backlight needs to be designed around such factors as the size of the glass and the type of polarizer. The tooling cost of the backlight tends to be greater than the cost of the LCD. This leads many companies not to incorporate a backlight or switch over to a monochrome graphics LCD module with a built in backlight.

These displays are available in standardized configurations such as 16x2. The first number, 16, is the number of characters, letter/numbers/ punctuation marks. The second number, 2, is the number of rows. In short a 16x2 is two rows with each row holding 16 characters, for a total of 32 characters. The most common configurations are 8x1, 8x2, 16x1, 16x2, 20x1, 20x2, (20x4, 40x1, 40x2, 40x4 and 16x4 decreasing in popularity)

One key advantage of the standardized configurations is that the display you purchase from LCD supplier "A" will also be available from LCD supplier "B". This reduces the probability of a single source LCD module.

Backlight Options: The majority of character LCD’s have the option of a backlight with no tooling cost. Backlights are available in 3V, 3.3v and 5V; although 3V and 3.3V backlights may have a slightly higher cost and MOQ at this time. Look for this price difference to go away in the near future.

LED’s are either mounted behind the LCD (aka backlit) or they are attached on the side of the display (aka side lit). Backlit displays tend to be 3mm to 7mm thicker than side lit LED’s.

At this time we recommend that white LED’s be side lit only. Backlit white LED’s will produce hot spots, areas of brightness and areas of darkness; this will give the display a polka dot pattern.

PCB/Pin out: Character LCD modules that are mounted on a PCB (printed circuit board) are called COB, Chip on board. This is the most common type of character display. COB module sizes are standardized, but the size of the PCB can be modified to meet the customer’s needs. There are times when the customer’s product lacks enough room for the PCB and sections of the board need to be removed. Some applications require the location of the connecting cable to be moved. The pin out on the PCB can easily be modified to meet the designers need. Modified PCB’s require a one-time tooling fee.

Some Graphics provide a fast enough frame rate to display videos. These displays are available in standardized configurations such as 128x64. The first number, 128, is the quantity of dots along the Horizontal, or X direction. The second number, 64, is the quantity of dots along the vertical, or Y direction. There are a total number of 128x64 = 8,192 dots that can be turned ON and OFF independently of each other. The most popular versions of a graphics display is the 128x64 (most common), 122x32, 240x120, 320x240, and 128 x 128.

Dot matrix displays have the option of a backlight without the need to pay tooling. The most common type of backlight is the LED. EL backlights are not as common but do offer a more even flow of light. CCFL (Cold Cathode Fluorescent Lamps) backlights were very popular with larger graphics display. Unfortunately this type of backlight has been discontinued by most suppliers. A large number of older products still make use of CCFL. The bad news is that there is no drop-in equivalent for this display. The best option is to design in a new display with a LED backlight.

Graphic LCD Displays can be customized in the same way as a character display. The tooling cost and MOQ is much higher. Your best option is to locate a standard off-the-shelf display that will work. Then, before you begin your design, locate a second source for the exact module. It is not wise to be locked into a single source.

FSC Displays, unlike character and graphics LCD’s, are not an off-the-shelf standardized item. Each display is customized to meet the needs of each customer. MOQ’s for this technology are around 500 to 1K displays. There is a one-time NRE fee to build to match your specs.

The main option of this module is the ability to choose the size of glass. At this time the largest size FSC is a 7-inch diagonal. This is expected to increase as the technology matures.

This is a 16 character by 2 line display with white text on blue background. The screen utilizes the standard HD44780 LCD interface. This display requires a 3.3V source.
