Everyone knows that the working temperature of conventional TFT LCD screen is -20 to 70 degrees, the storage temperature is -30 to 80 degrees, and the working temperature of wide temperature TFT LCD screen is -30 to 85 degrees. In order to pursue a wider working temperature, some customers will test whether TFT LCD screen can work normally under extreme temperature. Many customers find that the words displayed on the LCD screen become very light when the temperature is very low, and the words become very dark when the temperature is very high. What's going on?

mainly reflected in high-speed transmission, simplified wiring, low power consumption, high compatibility and other aspects. The following is a detailed analysis of its "advantages" from the perspective of technical principles and practical applications

Many customers have reported that touchscreens easily separate from the casing in extremely cold or hot environments. This is usually due to the use of ordinary double-sided tape to fix the touchscreen. Shenzhen Hongjia Technology engineers, through extensive research, have found that using VHB double-sided tape around the edges of the touchscreen cover glass solves this problem of screen separation from the casing. In the assembly of high-end touchscreens (especially for demanding industrial, automotive, outdoor, and high-end consumer electronics products), using 3M VHB double-sided tape to fix the cover glass has become a "gold standard" process. Its advantages far outweigh traditional liquid adhesives or ordinary double-sided tapes.

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.

At present, the touch technologies applied to products mainly include infrared, resistive, capacitive, surface acoustic wave, optical image, image recognition, panel induction, electromagnetic, light spot, and ultrasonic. The following is an analysis of the advantages and disadvantages of various touch technologies.

Shenzhen Hongjia Technology is mass-producing 2.35-inch LCD displays with a resolution of 272*480, IPS full viewing angle, and high-definition clarity. It uses mature drivers such as ST7365 or ILI9488, supports SPI/MCU/RGB and MIPI interfaces, and is compatible with microcontrollers, saving overall system costs. Previous TFT screens smaller than 2.4 inches were mostly low-resolution 240*320, with large pixel pitch and insufficient image detail. To meet the increasing demand from customers for finer display quality
