The manufacturing process of the 2.4-inch 450*600 resolution LCD display includes the following steps to ensure high performance, durability and reliability of the product:
- After the base glass plate is prepared, the thin film transistor (TFT) array is constructed。
Color film production:
RGB color filters are created on the film substrate using photolithography, enabling the screen to display rich colorsLiquid crystal injection and alignment:
A liquid crystal groove forms between glass substrates. In addition,the liquid crystal material is injected. Molecular alignment ensures neat arrangement. This guarantees a clear display from all angles.
Packaging and assembly:
Align the two substrates to the package to form a closed liquid crystal layer.Moreover, add a polarizer at the same time so that the LCD screen can display images normally.
Backlight module assembly:
Install the LED backlight module on the back of the liquid crystal unit.Then, evenly distribute the light source through the diffusion plate to ensure clear readability under various lighting conditions.
Driver IC binding and interface connection:
Connect the display screen to the driver IC using SPI, MCU, or MIPI interfaces, ensuring compatibility with various systems. Use COG or FPC technology for compact module designTouch layer (if any) bonding:If the display screen has a touch function, bond the touch layer to the display screen, using the OCA (optical clear adhesive) process to ensure no bubbles and high touch sensitivity.
Performance and reliability testing:
(1) For example,perform functional tests on brightness, contrast, resolution, color accuracy.Next, touch sensitivity to ensure standard performance.
(2) Conduct temperature cycle tests (-30°C to +80°C) to confirm stable operation in harsh industrial and medical environmentsAging test:
Perform a long-term power-on aging test on the display screen to ensure that it can operate stably for a long time under high load conditions.Appearance inspection and packaging:
Defective products are removed after inspection, and the rest are packed in anti-static bags and shockproof packaging for safe transport.
The 2.4-inch LCD display features high performance and reliability. It excels in medical equipment, handheld devices, and industrial instruments. It is also suitable for various complex environments.
Conduct temperature cycle tests (-30°C to +80°C) to confirm stable operation in harsh industrial and medical environments.
