why TN LCD screens are brighter than IPS LCD screens when using the same backlight brightness. Today, engineers from Shenzhen Hongjia Technology will explain this. First, TN (Twisted Nematic) and IPS (In-Plane Switching) LCD glasses have fundamental differences in transmittance, which directly leads to differences in their display effects (such as contrast, color, and viewing angle).

​Our company has successfully mass-produced 2.3-inch TFT horizontal screens with a resolution of 480*360 and IPS full viewing angles, filling the long-term vacancy in the 2.3-inch horizontal screen market with only low resolution and no full viewing angles.

IGZO displays can be seen as Sharp’s specialty. Recently, Sharp’s smartphones launched in the Japanese market are all equipped with IGZO displays without exception. It is worth noting that the biggest highlight of Sharp mobile phones equipped with this screen is the "ultra-long standby". Of course, this is also the advantage of the IGZO display. Sharp AQUOSPHONEZETA, which has the longest standby time in the history of Japanese operator DoCoMo, has officially benefited from the low power consumption of the IGZO display.

In short, for small-sized LCD screens, QSPI is a better choice: through pin multiplexing and queue mechanism, while maintaining sufficient transmission rate, PCB design and master control resource usage are greatly simplified, which is especially suitable for scenarios that require dynamic display and limited space. SPI is only applicable to extreme cases where the driver IC does not support QSPI or has extremely simple functions. When actually selecting, it is necessary to first confirm the interface specifications of the screen driver IC (some screens support both SPI and QSPI, which can be switched by configuring pins).

The HJ2101-01 is a 2.1-inch round LCD that supports SPI/MCU/QSPI interfaces, including 8/16-bit MCU interfaces. It supports 540*540, 480*480, and 360*360 resolutions, delivering vibrant and lifelike colors. The 2.1-inch round LCD utilizes an incell process and features a multi-point capacitive touchscreen. It only includes a single driver IC, reducing debugging time and overall module thickness. This 2.1-inch incell round LCD is suitable for a wide range of electronic devices, including smart homes, consumer electronics, and industrial control equipment.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in the research and development, production and sales of 1.14-inch to 12.1-inch LCD screens and matching touch screens. It has rich experience in dealing with backlight leakage and can meet the demanding requirements of our customers. We can also accept customization. Customers are welcome to email us for consultation.
