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.

including various heterogeneous display screens (strip screen, square screen, circular screen and transflective LCD screen).

Shenzhen Hongjia Technology has developed SPI display screens of multiple sizes to meet the increasing demand for SPI interface display screens from market customers, including 1.47-inch SPI, 1.3-inch SPI, 1.54-inch SPI, 1.96-inch SPI, 2.0-inch SPI, 2.2-inch SPI, 2.4-inch SPI, 2.8-inch SPI, 3.2-inch SPI, 3.17-inch SPI, 3.5-inch SPI, 3.97-inch SPI, 4.3-inch SPI and other products. They support 3-wire and 4-wire, and high-resolution SPI interfaces. Customers are welcome to email us for consultation.

the HJ2220-02, a 2.22-inch bar-type LCD screen. It features a 180x454 resolution and an SPI interface, making it ideal for microcontroller-based applications. Utilizing in-cell technology and an integrated multi-touch panel, it employs the SPD2010 driver IC to control both display and touch functions. This integration simplifies debugging and is highly user-friendly for hardware engineers. The module boasts an ultra-slim profile and uses a standard 30-pin connector with a 0.5mm pitch.

In short, ACF conductive adhesive is a core technology in the production of modern LCD screens (especially high-end, high-resolution, and flexible screens). It is more than just a "glue"; it is a sophisticated electrical interconnect material. Its performance directly affects the connection reliability, yield rate, and ultimate performance of the display.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.
