Product Introduction

Chenghao Display 4 Inch Lcd Touch Screen is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching device. This model is composed of a TFT LCD panel, a driving IC, a back-light, a capacitive touch panel and FPC.
This touch screen module has a color display area with a diagonal measurement of 3.95 inches, which can display 480x800 pixel videos or pictures. Thanks to the use of IPS display technology, the touch screen module supports 80/80/80/80 free viewing angles. In terms of appearance, the touch screen module is equipped with an all in black capacitive touch glass cover, which supports high-sensitivity multi-touch sensing. In addition, in order to better improve the adaptability of the touch screen module to the ambient temperature, our engineers have adopted a wide temperature design for the module, which allows it to operate stably within the temperature range of -20 ~ +70 ℃.
It should be pointed out that Chenghao Optoelectronic, as a professional LCD manufacturer, has rich experience in LCD design and customization. We can modify and customize the backlight brightness, interface type, and wiring of the touch screen module according to customer requirements to meet the actual needs of customers.
