In the production of phone screens, common display technologies and manufacturing methods include:

LCD (Liquid Crystal Display):

LCD is a type of display technology that uses a backlight to illuminate liquid crystals. These liquid crystals control the passage of light to create images on the screen. LCD screens are commonly used in various devices. They offer good image quality and color accuracy, but they are generally less power-efficient compared to OLED displays.


TFT (Thin Film Transistor) is a type of LCD technology that uses thin film transistors to control the arrangement of liquid crystals. These transistors are integrated into the pixels on the display, allowing for precise and individual control of each pixel’s behavior. TFT technology is widely used in various devices, including mobile phones, computer monitors, and televisions, to provide faster response times and better image quality compared to traditional LCD displays.


In-cell is a type of touch-sensitive technology integrated directly into the display panel itself. It eliminates the need for a separate touch layer, making the screen thinner and lighter. In-cell displays are commonly used in smartphones to achieve a slimmer profile and better touch responsiveness.

OLED (Organic Light-Emitting Diode):

OLED is a display technology that uses organic compounds to emit light when an electric current is applied. Unlike LCDs, OLED displays don’t require a separate backlight, allowing them to achieve better contrast and power efficiency. OLED screens can produce true blacks, vibrant colors, and have faster response times, making them popular for high-end smartphones.

Hard OLED:

Hard OLED is a traditional rigid OLED display that cannot be bent or curved. While it lacks the flexibility of Soft OLED, it is still widely used in various electronic devices due to its excellent image quality and reliability.

Soft OLED:

Soft OLED refers to flexible OLED displays that can be bent or curved. These screens allow for innovative form factors in devices and are often used in smartphones and wearable devices with curved or foldable designs. Soft OLEDs are more resistant to damage from impacts and offer a more immersive viewing experience.
