TFT LCD touch displays are becoming more prevalent every day, in devices that range from consumer electronics to industrial and medical equipment. While design concepts for the use of TFT touch displays are well established, engineering and product design teams often come up against problems that are hard to solve. Following best practices on how to use TFT LCD touch screen can reduce a lot of "hair-pulling".

If the applied ground approach for a device equipped with a TFT touch display doesn’t follow best practices, a variety of issues can arise. Common challenges associated with grounding:

In general, there are two key considerations: keeping ground connections as short as possible, and keep impedance to a minimum. This requirement is particularly critical in ground connections between display housing and touch controller. The diameter of the ground connection also has an effect, though it is less important than length.

Any floating conductive parts near touch sensor can cause erratic behavior in touch function. So they all should the same ground potential as the touch controller.

To address those issues, you need to follow best practices, including physical device assembly and grounding design. And those are just the top challenges, engineer will encounter a range of additional challenges, like longevity, slim design, and so on. Partnering with a hardware provider like Topway, who can advise you at every step along your path to market, is critical.

The TTL serial Nextion display is the best balance HMI solution between cost and benefit with low and decreased learning curve. See Nextion Editor Guide and Instruction Set.

A classic data logger would use a MCU and its GPIO pins, a SD card, a RTC, an LCD status display and many lines of code. Today, I"ll show you that you can have all in one, using a Nextion Intelligent series HMI and thus reduces cost and development time: First, the Intelligent series has everything "on board", the MCU, the GPIO pins, the RTC, the screen, and the SD card. Second, a very powerful component, the Data Record is available for these HMI displays in the Nextion Editor, which saves us, let"s say around 500 lines of C code. But telling you this is one thing, giving you a demo project at hands which covers all functionalities and which you can modify and extend as you need for your project is today"s topic.First of all, a happy new 2023! I"ll use this occasion to introduce a new type of Sunday blog post: From now on, every now and then, I"ll publish a collection of FAQ around a specific topic, to compile support requests, forum posts, and questions asked in social media or by email...Whatever you are currently celebrating, Christmas, Hanukkah, Jul, Samhain, Festivus, or any other end-of-the-civil-year festivities, I wish you a good time! This December 25th edition of the Nextion Sunday Blog won"t be loaded with complex mathematical theory or hyper-efficient but difficult to understand code snippets. It"s about news and information. Please read below...After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?

The gen4-FT813-70CTP-CLB display is an embedded SPI display from 4D Systems. It features a Capacitive Touch panel with Cover Glass with an integrated FTDI FT813 Video Engine.

This display provides four-in-one functionality, a TFT LCD Display, Audio with amplifier enabling, Capacitive Touch screen, and an integrated Video Engine. This combination built directly into the screen allows for simple integration into a number of applications.

Used to describe a clocked parallel TFT connection that uses 18 data lines (6 for Red, 6 for Green, 6 for Blue) as well as Hsync, Vsync, data enable, and pixel clock to transfer data to the TFT. Theoretical color depth is 218 or 262,144 colors.

Used to describe a clocked parallel TFT connection that uses 24 data lines (8 for Red, 8 for Green, 8 for Blue) as well as Hsync, Vsync data enable, and pixel clock to transfer data to the TFT. Theoretical color depth is 224or 16,777,216 colors.

A liquid crystal display structure in which switching transistors or diodes are attached to each pixel to control the on/off voltage. It produces a brighter and sharper display with a broader viewing angle than a passive matrix display. Also known as AMLCD (active matrix liquid crystal display). See TFT (thin film transistor).

This is often described as a matte coating as it is non-reflective to the user since it diffuses rather than reflects ambient light. It provides a method for manufacturers to avoid glare on the viewing surface from other light sources and has been used in the LCD monitor market for many years since the first TFT displays started to emerge. The matte coating is included as an outer polarizing later which has been coarsened by mechanical or chemical processes. This achieves a surface coating which is not smooth and so can diffuse ambient light rather than reflect it.

An adhesive is applied between the display and touch panel using the inactive area around the perimeter of the module. This bonding method results in some inactive space ‘air gap’ between the touch panel substrate and the display. This is the most cost-effective and common solution.

AMOLED is Active Matrix OLED. An Active Matrix OLED uses a TFT (Thin Film Transistor) transistor-per-pixel architecture. Using a transistor-per-pixel allows higher resolution displays to be made and avoids the problems associated with high duty cycle passive displays.

An anti-reflection (AR) coating is a type of optical coating applied to the surface touch panel to reduce reflection. Many coatings consist of transparent thin film structures with alternating layers of contrasting refractive index. Layer thicknesses are chosen to produce destructive interference in the beams reflected from the interfaces, and constructive interference in the corresponding transmitted beams.This makes the structure’s performance change with wavelength and incident angle, so that color effects often appear at oblique angles. Good performance can often be achieved for a relatively wide range of frequencies: usually a choice of IR, visible, or UV is offered.

A backlight is used behind the LCD glass to allow the LCM to be read in dark conditions. The vast majority of backlights are now LED. Historically there were also EL (electroluminescent) and CCFL (Cold Cathode Fluorescent Light) backlights, but as LED efficiency has increased and cost has decreased, EL and CCFL backlights have all but disappeared.

A frame of plastic or metal, fitting over the LCD glass, to protect the edges of the glass and actas a pressure device, compressing the elastomer connector between the PCB and LCD glass.

Normally an LCD’s backlight is set to the brightness that will make a white pixel fully illuminated. CABC automatically dims the backlight to the lowest level required for the brightest pixel on the display.

Character LCDs include a fixed CGROM to define the bulk of the characters they display. However, since the CGROM cannot be changed the designers also included the CGRAM — a small number of characters (typically 8) that can be redefined at run-time. These eight characters are usually mapped to characters 0DEC (0x00HEX) to 7DEC (0x07HEX). The CGRAM definitions can be used to make small animations, bar graphs, and similar small graphic or sprite images. This term very likely has its beginning in the granddaddy of all LCD controllers, the venerable Hitachi HD44780.

The CGROM stores the font that is displayed on a character LCD. When you tell a character LCD to display the letter ‘A’, it needs to know which dots to turn on so that we see an ‘A’. This information is stored in the CGROM. By definition, (since it is a ROM) the font that is stored in the CGROM cannot be changed. Be sure to check the datasheet of the character LCD module to make sure that it can display the characters you need. Typically, a CGROM for a character display module has 240 characters defined. The lower half of the CGROM maps to the normal ASCII characters. Since the early character display controllers were designed in Japan, many CGROM have Japanese characters in the upper 128 positions. There are also some CGROMs that have European or Cyrillic characters in these upper locations.

The WS0010 is a more modern character OLED controller, and the designers have included several CGROMs that can be chosen at run-time, so there is not the need to lock in a particular character set at design time. Since the CGROM is completely determined at the time of manufacture of the LCD controller, the designers also included a CGRAM, which allows the bitmaps of a few characters to be redefined at run-time. This term very likely has its beginning in the granddaddy of all LCD controllers, the venerable Hitachi HD44780).

A capacitive touchscreen panel consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO). As the human body is also an electrical conductor, touching the surface of the screen results in a distortion of the screen’s electrostatic field,measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing.

The Display Data RAM holds the letters that get shown on the LCD of a character LCD module. For instance, the letter ‘A’ is stored in its ASCII equivalent 65DEC (0x41HEX) in the DDRAM.

So a 20×2 character LCD would have enough DDRAM to store 40 letters. The value in the DDRAM is used to find the correct bitmap in the CGROM (Character Generator ROM) or CGRAM (Character Generator RAM), it is this small bitmap that gets displayed on the LCD. This term very likely has its beginning in the granddaddy of all LCD controllers, the venerable Hitachi HD44780.

Translucent material used for light diffusion placed between backlight lighting sources and the back side of an LCD. This material will create a more uniform backlight for an LCD from several unique sources of light.

Apple has been granted a patent in 2011 that describes a method for fabricating thin DITO (Double-Sided Indium Tin Oxide) or SITO (Single-Sided Indium Tin Oxide) touch sensor panels with a thickness less than a minimum thickness tolerance of existing manufacturing equipment. In one embodiment, a sandwich of two thin glass sheets is formed such that the combined thickness of the glass sheets does not drop below the minimum thickness tolerance of existing manufacturing equipment when a thin film process is performed on the surfaces of the sandwich during fabrication. The sandwich may eventually be separated to form two thin SITO/DITO panels.

Refers to a graphic controller from Bridgetek/FTDI. EVE graphic controllers are easy to use and can control the display, touch, backlight, and audio features of an embedded system, with each appearing to the host MCU as a memory-mapped SPI device. The host MCU sends commands and data using SPI protocol. EVE modules accept high level commands, simplify writing images and fonts (included angled fonts) on TFTs. Fonts, buttons, and tables can each be easily sent to a TFT using a one-line command.

A silicone rubber strip made up of sequentially spaced conductive and non-conductive material. A thin conductive material used to make connections between an LCD and a PC board.

A dead short is created when excess DC voltage is applied to an LCD. Conductive particles from one piece of glass are transferred through the liquid crystal fluid and deposited on the conductive surface of the opposite piece of glass.

The space left between the epoxy seals on one end of the LCD glass after assembly. This space,used to fill the glass with the liquid crystal fluid, is noted by a mound of epoxy.

An LCD construction technique where the cell geometry is optimized for maximum contrast and viewing angle. The geometry is different for each LCD fluid.

Capacitive touch can be classified into glass- or film-substrate produced. Glass-substrate capacitive touchscreens are found in Apple’s iPhone and Samsung’s Galaxy S phone. The iPhone uses a glass-glass (GG) structure that forms the X-axis sensing electrode on the upper surface of a glass substrate and Y-axis sensing electrode on the bottom. While Apple’s GG method and other mobile phone makers’ glass/film (GF/GFF) designs are becoming mainstream, attempts to develop products such as G1F, and OGS (One Glass Solution) with better transmittance and thinness will continue. OGS is cover window integrated touch, which does not require separate touch sensor.

HDMI means it is able to send a lot of data, very quickly. However, HDMI isn’t an analog communication like VGA, S-Video or parallel like 24-bit or 18-bit RGB TFTs. HDMI is actually a high-speed serial interface using a fancy TMDS (Transition Minimized Differential Signaling) protocol.

Typically, both the master and slave are implemented in hardware. The I2C master can be implemented in software quite easily, but it can be rather difficult to meet the timing requirements of I2C in a software slave implementation. As micro controllers continue to get faster, writing an I2C software slave will become easier. The I2C standard is pretty well defined, so there is not a huge amount of variation in I2C as it is implemented on LCD, capacitive touch and OLED controllers.

An in-cell display is a touch display in which the touch sensors are embedded within the screen. Traditional capacitive touchscreens have multiple layers of glass, including a capacitive touchscreen layer. In-cell displays eliminate the need for these external touch panel. This results in a thinner and lighter display than a comparative display with an external touch panel, enabling a sleeker final product for devices using an in-cell display.

An LCD is composed of two pieces of glass with a thin layer of liquid crystals between the glass layers. When a voltage is applied to the glass, the orientation of the crystals can be changed. This change in the crystal’s orientation (called polarization) will make either a dark or a light area, creating a character or image on the display.

A twisted nematic LCD design where the backlight is blocked when pixels are in the unselected state. Therefore, when no voltage is applied, the screen is black.

A twisted nematic LCD design where light is transmitted when pixels are in the unselected state. Therefore, when no voltage is applied, the screen is white.

OCA is also called dry bonding. Optical bonding, including LOCA (Liquid Optically Clear Adhesive) and non-liquid OCA tape, are used in a wide range of electronic equipment – especially those with touch panels. The adhesive is used to bond the touch panel to the main liquid crystal display, and also to bond any protective cover, such as the lens, to the touch panel. The adhesive is then cured onto the device through UV, heat, moisture, or a combination of these three methods, depending on the manufacturer and specifications. Major applications include capacitive touch panels, 3D televisions (3D TV), and glass retarders.

Optical bonding improves the optical performance of the display. It eliminates the air gap between the cover glass and the LCD, and usually includes an anti-reflective (A/R) coating (as well as anti-smudge and anti-glare treatments on the cover glass). Optical bonding improves the contrast ratio by reducing the amount of reflected light, thus improving the viewability of the LCD screen. This is especially important in outdoor.

Besides the optical advantages, bonding a sheet of glass to the LCD also improves the durability of the display. It can resist scratches, condensation, and has an improved range of operating temperatures. As touchscreen devices become ubiquitous in consumer markets, this increased ruggedness becomes even more important. Also, by reducing the light loss due to reflection, the battery life of the device can be extended as the device does not need as much backlight to power the display.

One Glass Solution is a touchscreen technology which reduces the thickness of a display by removing one of the layers of glass from the traditional capacitive touchscreen stack.  The touch sensor is made directly on the cover lens.

On-Cell Touch (OCT) technology permits the Projected Capacitive (PCAP) touch sensor layer to be built into the LCD structure. With this integrated structure, the touch functionality is embedded within the display itself rather than a separate touch screen component on top of the display. The reduction in the number of layers also reduces parallax errors providing a superior touch interface. Fewer layers also means backlight intensity can be reduced while providing the same brightness level. The usual multitouch display has an 88% transparency while an OCT display is 93%. This helps reduce lighting power requirements and extends battery life.

For optical bonding optically clear adhesive is applied over the entire surface between the display assembly and touch panel. This bonding method removes all air and air bubbles from the viewing area providing a more rugged and optically attractive solution. Removal of ‘air gap’ between the module and touch panel eliminates surface-to-surface reflections which degrade contrast and ultimately viewing angles, especially significant in sunlight conditions.

A resistive touch screen is made of two transparent layers of glass or plastic, each coated with a conducting layer of Indium Tin Oxide (ITO). The conducting sides face one another and are separated by an air gap. When pressure is applied by the user, the top layer bends and touches the bottom layer. This causes a small amount of current to flow at the point where they connect. The location of the touch event can then be measured by the sensors.

In this variant, if the top sheet has electrodes for the vertical direction (Y), the bottom sheet will have electrodes for the horizontal direction (X). The top and bottom sheets measure each others’ voltages and based on that sensors can determine the location of the touch point.

A technique where the alignment layer (Polyimide) on the LCD substrate is rubbed in one or more directions. This process aligns the liquid crystal molecules parallel to the buffing direction.

SPI is a simple serial bus that is often used by LCD or OLED controllers. SPI as implemented for OLED and LCD controllers typically uses a “3-wire SPI” or “4-wire SPI” scheme. SPI was originally championed by Motorola (now Freescale). In its original “pure” form SPI uses four signals:

TFTs are also known as “Active Matrix TFT LCD modules” and have an array of these thin film transistors fabricated on the glass that makes the LCD. By using this active transistor-per-pixel architecture, the contrast of each pixel is good, allowing bright full-color, full motion images to be displayed.

VA is also called VTN, PMVA, GDV, etc. it is a type of LCD in which the liquid crystals naturally align vertically to the glass substrates. When no voltage is applied, the liquid crystals remain perpendicular to the substrate, creating a black display between crossed polarizers. When voltage is applied, the liquid crystals shift to a tilted position, allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field. VA displays have a deeper-black background, a higher contrast ratio, a wider viewing angle, and better image quality at extreme temperatures over traditional twisted-nematic displays.

capacitive multi-touch panel sensor and component board in a rugged, plastic enclosure. Offered in black (-BK) colours, the device provides the engineer a low priced option which can shorten development time while enabling a production finished look for 4.3" or 5" colour TFT display solutions.

The Capacitive touch panel is activated with anything containing an inductive load such as a finger or stylus. It allows for multi-touch options. When using the capacitive touch screen, the display needs a separate controller to interface with the touch panel. The display for capacitive touch is brighter since the touch panel is transparent.

The Transmissive polarizer is best used for displays that run with the backlight on all the time. This polarizer provides the brightest backlight possible. If you have a need for a bright backlight with lower power drain, transmissive is a good choice for this TFT LCD display.
