This LCD display model is commonly included in Arduino kits, but those instructions work with any LCD display that has a 16 pins interface compatible with the Hitachi HD44780 LCD controller.

We come across Liquid Crystal Display (LCD) displays everywhere around us. Computers, calculators, television sets, mobile phones, and digital watches use some kind of display to display the time.

An LCD screen is an electronic display module that uses liquid crystal to produce a visible image. The 16×2 LCD display is a very basic module commonly used in DIYs and circuits. The 16×2 translates a display of 16 characters per line in 2 such lines. In this LCD, each character is displayed in a 5×7 pixel matrix.

Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backward to adjust the LCD contrast.

A 16X2 LCD has two registers, namely, command and data. The register select is used to switch from one register to other. RS=0 for the command register, whereas RS=1 for the data register.

Command Register: The command register stores the command instructions given to the LCD. A command is an instruction given to an LCD to do a predefined task. Examples like:

Data Register: The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. When we send data to LCD, it goes to the data register and is processed there. When RS=1, the data register is selected.

Generating custom characters on LCD is not very hard. It requires knowledge about the custom-generated random access memory (CG-RAM) of the LCD and the LCD chip controller. Most LCDs contain a Hitachi HD4478 controller.

CG-RAM address starts from 0x40 (Hexadecimal) or 64 in decimal. We can generate custom characters at these addresses. Once we generate our characters at these addresses, we can print them by just sending commands to the LCD. Character addresses and printing commands are below.

LCD modules are very important in many Arduino-based embedded system designs to improve the user interface of the system. Interfacing with Arduino gives the programmer more freedom to customize the code easily. Any cost-effective Arduino board, a 16X2 character LCD display, jumper wires, and a breadboard are sufficient enough to build the circuit. The interfacing of Arduino to LCD display is below.

The combination of an LCD and Arduino yields several projects, the most simple one being LCD to display the LED brightness. All we need for this circuit is an LCD, Arduino, breadboard, a resistor, potentiometer, LED, and some jumper cables. The circuit connections are below.

Liquid crystal displays (LCDs) are comprised of tiny elements of color called pixels. Pixels have dimensions of a few microns or less and consist of three subpixels colored red, green, and blue. The popular acronym, RGB, is often used to delineate the color of a specific pixel within 16.7 million different color combinations. These tiny pixels are densely packed into television screens, computer monitors, tablets, and phones that utilize backlighting to illuminate each pixels and create the complex patterns we recognize as graphics and images today.

The most important concept in LCD technology is the behavior of liquid crystals. A twisted nematic liquid crystal layer acts to rotate (twist) the plane of polarization to align or misalign with the second polarizer. This means that if the polarizers are 90 degrees apart (see Figure 3, 4), then the twisted crystals will align with the second polarizer and permit light to pass through. Conversely, if the crystal layer did not exist, light would not pass through because the polarizers are oriented in such a way that the second polarizer blocks the light from the first polarizer.

Electrodes in LCDs function as on and off switches. The electrodes tune their voltage from on to off in 256 increments for each RGB subpixel. This is what gives 16.7 million different colors for each pixel (3 pixels, each with 256 shades; 2 raised to the 24th power).

In more primitive LCDs like those in digital watches or calculators, mirrors are used to reflect natural light to produce the digits we see on the displays. For more modern, high-power screens like TVs and laptops, backlights are used to illuminate the pixels. The backlights are often rectangles or strips of flourescent lamps or light emitting diodes (LEDs).

The most elementary concept of a computer screen lies in the manipulation of light. The goal here was to provide a simple overview of the primary components of a liquid crystal display (LCD) and its deceptive mechanics. Often, LCDs are thought of as complex systems not worth understanding, when in reality, an LCD consists most primitively of six parts: two polarizers, two electrodes, a liquid crystal layer, and a backlight or mirror. Once these mechanisms are understood, the complexity of a LCD remains in the deception of the human eye - not in the nature of its physics.

A Liquid Crystal Display (LCD) can be of the character type or graphics type. Graphic LCD displays have a matrix of pixels that can be used to display text and graphics, e.g. 128 by 64 pixel display. When starting electronics, a character LCD will usually be used.

Character LCDs can display characters only and are divided into rows of characters. For example a 2 by 16 character LCD display has two lines that can display 16 characters each. An example of a 2 × 16 character display is shown below.

LCDs are available with or without a backlight. A backlight is just a light in the LCD that lights up the display making it easier to read in low light conditions.

There are a number of character LCDs based on the Hitachi HD44780 LCD controller and driver IC. These displays are software compatible and available from several different manufacturers. There are even pin compatible character LCDs that are available from different manufacturers. Always check the datasheet from the manufacturer to make sure of the pin numbering and pin functions of the LCD display that you are going to use.

It is possible that other displays are also compatible with this one. If a backlight is not present, then pin 1 and 2 may be missing. Other LCDs may have the pins at the top and pin numbering may start with 1 on the left.

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

If you are concerned about pixel anomalies on your display, take your Apple product in for closer examination at an Apple Store, Apple Authorized Service Provider, or an Independent Repair Provider. There may be a charge for the evaluation. Genuine Apple parts are also available for out-of-warranty repairs through Self Service Repair.*
