how to program lcd display brands
Before you get involved with LCD display programming, its critical you first choose the correct LCD display for your product. All LCD modules can be classified into one of two categories: those requiring a controller/driver chip and those that don"t.
Displays requiring a controller/driver chip to interface with your product require a programmer to write software code, sometimes referred to as firmware, to connect the LCD to the end product. Those that have a controller/driver are much easier and faster to program. Specifically, this article will address programming the character or alphanumeric displays with a parallel bus (a parallel bus LCD sends and receives 4 bits, 8 bits or 16 bits of data at a time).
The second category, those that don"t require a controller/driver chip, are called static or segment displays. This means that there is one connection on the LCD for each segment. Although this eliminates the controller chip, it requires a great deal of connections between the display and the customers product.
So what exactly is this all important piece of technology—the controller/driver (C/D)—that will make your life easier through quick and simple programming? It is a small microprocessor whose function is to convert the designers’ firmware/software into characters, numbers, and punctuation marks. The C/D makes it easy for the product designer to quickly program the character display. Inside each C/D is a character table, sometimes referred to as a character map or font table, which contains pre-loaded letters, numbers, and punctuation. The table allows the designer to call out the requested character by addressing the number of that character. In other words, the letter ‘T’ may be the number 27 and the n-dash (i.e. “-”) could be number 122. This eliminates the need to create each character from scratch and reduces the amount of time necessary to program the LCD module. In the font table shown below, the letter ‘P’ would be displayed when the designer calls the number sequence below.
D0=0, D1=0, D2=0, D3=0, D4 =0, D5=0, D6=1, D7=1. The letter Do, D1 and so on above means data bit 0, data bit 1 etc. Most character displays use eight data bits.
The character table contains 255 possible characters. This number of characters is sufficient for one language, but would be impossible to display every character in every language when limited to only 255 options. This challenge is solved by making use of a different C/D for each language. You can order a C/D for French, German and many other languages.
There are several manufactures of C/D’s including Seiko, Epson, Toshiba, and Sunplus. There are distinct advantages of having multiple makers in multiple places in the world. Specifically, you won’t have to worry about a delay in the supply chain that is the result from the constraint of the C/D being made by only one or two manufacturers. You don’t want anything to delay the launch of your product.
Character LCD displays contain 14 pins if no backlight is attached and 16 pins when an EL or LED backlight is included with the module. Below is a breakdown of each pin and the function of that pin. The function of these pins directly relates to your success at programming character LCD displays, so pay attention!
The Ground is necessary for the voltage and the contrast adjust to reference. Ground, also referred to as zero volts, is required on all electronic devices. Electrical ground is similar to the ground floor of a tall building. All the floors above the ground floor are positive and all the floors below the ground floor, the basement, are negative. The ground pin on the LCD is connected to the ground on the customer’s product
This is the Logic voltage necessary to drive the LCD. There are two common voltages for a character LCD, 3.3V (this is equal to two "aa" batteries in series) and 5V.
It is possible to order a character LCD with both a positive and negative voltage. This option is not very common and is seen in replacing older discontinued displays.
We do not recommend using the same Ground and VDD connections to supply both your LCD logic and your LED backlight. It is better to use a separate power for your backlight which is what pins 15 and 16 or the A and K tab on the side of the LCD are designed for.
This is the connection for the contrast adjust. This function is to modify the voltage between VDD and Ground and then to adjust the contrast. If you are not able to achieve the desired contrast, it may be necessary to add a resistor to the back of the printed circuit board. The addition of the resistor alleviates the low contrast issue.
Register Select has two positions: 1 (on or high) or 0 (off or low). When RS is low (0), the data is to be treated as an instruction such as ‘move the position of the cursor’ or ‘clear the screen’. When RS is high (1), the data being sent to the display is a letter, number or punctuation mark that is to be displayed on the screen.
The RW line is the "Read/Write" control line. When RW is low (0), the information on the data bus is being written to the LCD. When RW is high (1), the program is effectively querying (or reading) the LCD. Only one instruction ‘check LCD status’ is a read command. All others are write commands--so RW will almost always be set to low.
The data bits on a parallel LCD display can accept up to 8 bits of data at a time. It is possible to use just four of the eight data bits if your microcontroller lacks enough connections to drive all 8 bits; however, this is a slow transfer of information. The data bit lines are numbered DB and begin at number DB0, DB1 etc. up to DB7.
These two lines are called A for Anode and K for Cathode. Yes, it is strange to use the letter K for a word that starts with a C, but that is an entirely different subject!
The anode is the positive voltage for the backlight, while the K is the ground for the backlight. You have options when it comes to ordering your backlights; you can order an LCD display with either a 3.3V LED backlight or a 4.2V LED backlight.
One key component in LCD display programming is to make sure the controller driver you have designed will continue in production. Over time C/D suppliers will discontinue various models. So, the issue you solved with maintaining a steady supply chain does crop up again when models become obsolete. To mitigate the inconvenience, when the IC is discontinued, the LCD supplier will recommend a replacement or compatible controller. This is where the word ‘compatible’ does not mean ‘exact drop in equivalent’; however, we find that a compatible controller is an exact match 95% of the time. If you find yourself in that unlucky 5%, then you will either need to make a last-time buy of the controller that is being discontinued or change the software on your product to match the new controller.

As technologies improve, business opportunities are born, and those who are willing can take advantage of the technology that is the LCD display module. How exactly?
The advertising industry has significantly benefited from the evolution of LCD. Now able to reach consumers far and wide with ease, entrepreneurs have taken advantage, and digital signage businesses are sprouting all around like mushrooms. But this doesn’t mean there is no more place for your start-up business. You need to know the WHY and the WHAT! Read on and find out what we’re talking about.
Gone are the days of giant billboards needing three to five men to replace the ad. Nowadays, all you need is an IT technician in front of a computer with access to all your properties.
One digital display can run energy drink ads in the morning, food buffet ads by noon, and pillow and bed ads in the evening. The ads and the time they are shown can be varied depending on when interest is at its peak.
Graphic LCD module and OLED display module development are at their peak! With various brands competing for the designation of the best display in the market, you have the pick of the litter regarding the best and most durable equipment to found your business on.
First and foremost, you need to invest in equipment. Equipment is not just about picking a brand that you like. Research their background. Check the comments on their products. It is better to invest in something expensive but of top quality than on something cheap only to suffer repairs and replacements down the road. Also, you need to think of the screen size, which will depend on many factors (i.e., location, product to be advertised, budget). Determine these things through research.
Research on prime advertising locations. Because of the adaptability of LED technology, you can place it almost anywhere: bus stops, elevator lobbies, at the back of moving vehicles. Just make sure you are not breaking any laws. Look up the necessary legal matters that need to be settled before settling on a location.
Because of the earlier said ease of installation and updating, a minimum number of employees are required. Barring the people you need to install the signage, a 100 m2 to a 1000 ft2 office is usually enough with a team of at least 8 to 10 people, from managers, secretaries, sales representatives, etc.
Utilize these tools and set-up your own business. Just follow a smart business plan, and you are good to go. It is always important to research and know the industry you are working in. Use the LCD technology to set yourself up for success!

LCD character displays are useful for displaying information without the need for an external monitor. Common LCD character displays can be connected directly to the GPIO pins, but such an approach requires the use of up to 10 GPIO pins. For scenarios that require connecting to a combination of devices, devoting so much of the GPIO header to a character display is often impractical.
Many manufacturers sell 20x4 LCD character displays with an integrated GPIO expander. The character display connects directly to the GPIO expander, which then connects to the Raspberry Pi via the Inter-Integrated Circuit (I2C) serial protocol.
There are many manufacturers of LCD character displays. Most designs are identical, and the manufacturer shouldn"t make any difference to the functionality. For reference, this tutorial was developed with the SunFounder LCD2004.
The device address for the GPIO expander depends on the chip used by the manufacturer. GPIO expanders equipped with a PCF8574 use the address 0x27, while those using PCF8574A chips use 0x3F. Consult your LCD"s documentation.
Another using declaration creates an instance of Lcd2004 to represent the display. Several parameters are passed to the constructor describing the settings to use to communicate with the GPIO expander. The GPIO expander is passed as the controller parameter.
