Common Mistakes to Avoid During LCD Replacements

Replacing a phone’s LCD might seem like a simple fix but it’s one of the most common repairs that goes wrong. From cracked displays to dead touch zones, many issues stem not just from a damaged screen but from mistakes during the replacement process itself.

Whether you’re a repair technician or a DIYer fixing your own phone, here are some of the most frequent errors people make:

⚠️ 1. Skipping Proper Diagnosis

Not every display issue means the screen is faulty. It could be a loose flex cable or a motherboard fault. Replacing the LCD without testing can waste time and money.

⚠️ 2. Using Poor Tools or Cheap Parts

Household tools aren’t designed for delicate phone internals. Cheap LCDs often lack brightness, have color issues, or fail within weeks. Always use professional tools and trusted parts.

⚠️ 3. Rushing the Process

Forcing the screen, ignoring adhesive cleanup, or skipping water-resistant seals can lead to long-term damage. A clean workspace, patience, and attention to detail matter more than speed.

⚠️ 4. Not Testing Before Full Assembly

This one’s a classic reassembling the whole phone only to discover the new screen doesn't work. Always test display, touch, brightness, and other features before sealing the device.

Want to dive deeper? We’ve broken down 13 common mistakes, including how to avoid damaging flex cables, what adhesives to use, and how to safely handle static discharge.

What are the reasons and solutions for the white screen when the industrial control LCD screen is turned on?

LCD industrial control LCD screen is now one of the devices that can be seen everywhere. Industrial industries have gradually used industrial control LCD screens, and industrial control LCD screens occasionally have white screens. So, how to solve the white screen failure of industrial control LCD screen? It is a very common phenomenon that the LCD industrial control LCD screen turns on the black screen or blue screen. Black screen and blue screen are problems with the system or hardware, and the white screen failure of the display screen when it turns on is generally a failure of the LCD industrial control LCD screen itself.

Causes of LCD industrial control LCD screen failure:

The white screen failure of LCD industrial control LCD screen may be caused by three aspects: problems with the LCD panel drive circuit, problems with the LCD panel power supply circuit, poor contact of the screen line, and problems with the motherboard control circuit.

If the industrial control LCD screen can be turned on normally, it means that the backlight and high-voltage generation circuit are working properly, indicating that the LCD panel has not received the drive signal; if the screen disappears after shutting down, and then a white screen occurs, it may be a problem with the power board.

This means that no matter whether it is turned on or off, as long as the power is plugged in, the high-voltage generation circuit is in working condition and the backlight source is always lit. That is to say, the high-voltage generating circuit is no longer controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generating circuit has lost control. Since the switching signal sent by the motherboard microprocessor is generally controlled by several transistors, the fault may be that the transistor that controls the switching signal is damaged.

LCD industrial control LCD screen fault repair:

1. Remove the shell and check whether the screen line interface is loose or not connected properly.

2. Then turn on the power switch and use a multimeter to measure whether the power supply voltage of the screen line interface is normal. If the power supply voltage is normal, check whether the timing signal and drive signal in the LCD panel drive circuit are normal; if not, then check whether the fuse resistor or fuse inductor near the output end of the screen line is open or damaged. If damaged, replace the damaged components.

3. If the fuse resistor or fuse inductor near the output end of the screen line is normal, then check whether the output voltage of the DC-DC voltage conversion circuit that powers the LCD industrial control LCD screen is normal. If the output voltage is abnormal, check the fuse resistor, PWM controller, switch tube, inductor coil, filter capacitor and other components in this power supply circuit, and then replace the damaged components.

4. If the output voltage of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output of the DC-DC voltage conversion circuit and the screen line interface. Check and replace the damaged components. 5. If the power supply voltage of the screen line interface is normal, then check whether the timing signal and drive signal in the LCD panel drive circuit are normal. If not, check the output signal, input signal and power supply voltage of the chip that generates this signal to determine whether the drive chip is damaged. If damaged, replace it.

2. Structure, Working Principle, and Classification of LCD

LCD does not emit light; rather, it is a passive display technology that displays by irradiating liquid crystal material with external light. The figure shows the basic structure of the LCD.

The basic structure of an LCD is depicted in Figure 10-1. The liquid crystal material is sandwiched between two conductive glass electrodes: upper (front) and lower (back). The liquid crystal molecules are stacked vertically and twisted 90 degrees at the top and bottom. External incident light travels through the upper polarizer to produce polarized light, which is rotated by 90° through the parallel-arranged liquid crystal material before being reflected by the reflector through the bottom polarizer, which is perpendicular to the upper polarizer and transparent. If the upper and lower electrodes, plus a certain voltage, under the action of the electric field forced to add the electrode part of the liquid crystal molecules into a vertical arrangement, the role of its spinning disappears, resulting in the polarized light incident from the upper polarizer is not rotated, the light cannot be returned to the lower polarizer, and it is black. When the voltage is removed, the liquid crystal molecules return to their twisted configuration. As a result, the electrodes can be shaped in a variety of ways to display different words, numbers, and images.

3. There are numerous ways to categorize LCDs

1) Classification using electro-optical effects The electro-optical effect refers to the role of electricity in causing the original arrangement of liquid crystal molecules to alter, resulting in changes in the optical properties of the liquid crystal box, i.e., electricity modulating light through the liquid crystal molecules.

LCD liquid crystal displays are classified into three types based on electro-optical effects: electric field, current, and electro-thermal. The electric field effect can be classified as twisted nematic (TN), GH, or super-twisted (STN), among others. TN-type and STN-type LCDs are now often employed in microcontroller applications.

2) Classification based on display content LCDs can be classified into three types based on their display content: field type (also known as stroke type), dot-matrix character type, and dot-matrix diagram.

Field-type LCDs are liquid crystal displays made up of lengthy, brushstroke-like display pixels.

The dot matrix character set has 192 built-in characters, including numbers, letters, and common punctuation marks. Users can also customize 5x7 and other dot matrix characters. Depending on the LCD model, there can be one, two, or four lines per screen, with each line displaying eight, sixteen, twenty, twenty-four, thirty, or forty characters.

In addition to displaying characters, the dot-matrix form of LCD liquid crystal display can also display a range of graphic information, such as Chinese characters.

3) Classification based on lighting method LCD liquid crystal displays can be split into two categories: backlit and non-backlit.

LCDs without backlights rely on the reflective coating on the back of the panel to reflect incoming natural light from below. Most LCD-equipped devices use natural light as a light source and do not require backlighting. If the product is used in low-light or dark situations, select an LCD monitor with a backlight.

4. What Is the Function of the Lamination Process in the Touchscreen

Touchscreen lamination is the process of applying a thin coating or layer to the surface of a touchscreen. This entails adding a protective coating of plastic or glass to the touchscreen. This layer protects the touchscreen against scratches, fingerprints, dust, dirt, and other environmental contaminants. It also improves the optical clarity of the touchscreen, making it easier to see images and text on the screen. Lamination can also be utilized to provide a decorative touch to the device by applying a logo or other graphic to the touchscreen.

This layer is commonly comprised of polyester or polycarbonate, and it is placed with heat and pressure. The layer is applied using a lamination machine, which provides heat and pressure to the touchscreen, allowing the protective layer to adhere to it. The heat softens the substance, and the pressure bonds it to the touchscreen. The lamination process usually takes a few minutes, depending on the size and complexity of the touchscreen. After the lamination process is completed, the touchscreen is cooled and the protective layer is kept in place to safeguard it from environmental toxins and damage.

Touchscreen lamination protects the touchscreen from damage and scratches while also improving its optical clarity and appearance. As it reduces glare and reflections from the touchscreen. Finally, lamination can be used to decorate the device by applying a logo or other graphic to the touchscreen.

Additionally, touchscreen lamination can be used to apply coatings such as anti-glare, anti-reflection, and anti-fingerprint coatings, which serve to reduce glare and reflections while also making the touchscreen simpler to clean. There are numerous tips for waterproofing throughout the laminating process.
