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.

Therefore, TTL (LVDS) is the screen cable, transmitting digital signals; RGB (VGA) is the external cable, transmitting analog signals—this is the fundamental difference.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.

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.

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.
