Our company successfully batch 3.5-inch semi trans

At present, Shenzhen Hongjia technology has developed and mass produced a 3.5-inch semi transparent and semi reflective LCD screen compatible with Xinli and Tongbao, with a resolution of 640 * 480 and a touch screen. The specification of FPC can be changed and the mold can be customized according to the requirements of customers, so as to ensure the stability of resources and long-term continuous supply. The 3.5-inch semi transparent and semi reflective LCD screen can not only display normally indoors, but also display excellent information without lighting the backlight in the outdoor environment with strong sunlight during the day. Since the utilization rate of the backlight can be minimized, the power consumption of the product embedded with the module can be greatly reduced and the service life of the backlight LED lamp can be prolonged.
Basic principle of semi transparent and semi reflective screen:
The secret of semi reflection and semi reflection lies in the semi reflective film. Like the glass of some buildings, some sunglasses and car stickers. The front is a mirror (which can reflect sunlight and provide a light source for reading in the sun), while the back of the mirror can see through the mirror (which provides a channel for the screen backlight).
General screens are divided into full transparent type and semi transparent and semi reflective type according to the "lighting mode"
Fully transparent screen - there is no reflector on the back of the screen, and the backlight provides light source. Advantages: excellent reading ability in weak light and no light. Disadvantages: the backlight brightness is seriously insufficient in outdoor sunlight. Relying solely on improving the brightness of the backlight will rapidly lose power, and the effect is not ideal. It is not feasible to achieve semi transparency simply by improving the brightness of the LED lamp, which will only shorten the service life of the LED lamp, reduce the battery life and increase the power consumption.
Semi reflective screen - that is, replace the reflector on the back of the reflective screen with a mirror reflective film. And a fully transparent backlight is added; It can be said that semi reflective and semi transparent screen is a hybrid of reflective screen and full transparent screen. It combines the advantages of both, with the excellent reading ability of reflective screen in outdoor sunlight and the excellent reading ability of fully transparent screen in weak light and no light.
The characteristics of the 3.5-inch semi reflective and semi transparent screen are: the backlight brightness automatically adapts to the outdoor environment. How strong the outdoor sunlight is, the backlight (sunlight) reflected by the reflective film will be. No matter how strong the outdoor sunlight brightness is, the stronger the ambient light is, the stronger the reflected backlight will be. You can completely not rely on additional backlight lighting equipment outdoors, so it saves a lot of power than the full transparent screen, and the reading effect is much better.
The semi reflective and semi transparent screen has mature technology, but the price is expensive. Few domestic manufacturers produce it. In addition to the price factor, the process requirements are relatively complex. First, the screen must be made of reflective material on the basis of its own material, and then it must have light-emitting plate at the same time, which makes it the advantage of integrating reflective screen and transmission screen, But there are no two shortcomings of the screen. In the outdoor daytime, under the sun, the larger the sun, the clearer you can see. When there is no sunlight, of course, you can see very clearly. As for the night, let alone the same. In addition, because the semi reflective and semi transparent screen not only emits light by itself, but also uses external light sources, another advantage of the semi reflective and semi transparent screen is that the eyes will not hurt the eyes like the transmission screen when looking at this screen for a long time. It is between the reflection screen and the transmission screen.
In short, the fully transparent type depends on the direct backlight display, the reflective type depends on the ambient light reflection display, and the semi transparent type is the perfect combination of fully transparent and fully reflective! If you want the best display effect and the least power consumption, the solution of "semi transparent display + backlight automatic induction switch" is the best choice!
