In today's digital and automated industrial era, equipment such as industrial touchscreen display, industrial panel odm, open frame panel pc, and various industrial grade monitor have become core devices in complex environments like industrial scenarios and outdoor operations. Taking products under the Zhichun of Chongchang as an example, their quality directly affects the stability and safety of subsequent use. The rigorous and comprehensive series of inspections before delivery are crucial for screening qualified products and avoiding usage risks. Compared with ordinary commercial displays, the inspection standards for industrial-grade products are more stringent. They not only include reliability tests to verify the "industrial-grade attributes" but also routine inspection items to ensure product integrity. These two aspects complement each other and jointly form the core basis for judging product quality.
In the pre-delivery inspection process of Zhichun products of Chongchang, such as industrial display and industrial panel pc, the following items are all mandatory inspections. Each inspection is carefully designed around the actual needs of its specific application scenarios:
1.IP65 Industrial-Grade Dustproof and Waterproof Test
The industrial environment is complex, and equipment like industrial touchscreen display often faces problems such as dense dust in workshops, rainwater erosion outdoors, or random liquid splashes in operating environments. Therefore, passing the IP65-level dustproof and waterproof test has become a necessary condition for products like industrial grade monitor. This test can accurately verify whether the tightness of the equipment shell meets the standards, effectively prevent dust from secretly entering internal components, and at the same time successfully resist damage to circuits, screens, and other key components caused by water splashes, fully ensuring the stable and normal operation of the equipment in dusty and humid harsh environments. For example, the relevant products of the Zhichun strictly follow this test standard to ensure that every piece of equipment delivered from the factory can adapt to complex environments.
2.Wide-Temperature Operation Test
From high-temperature and sweltering factory workshops to low-temperature and harsh outdoor operation sites, equipment such as industrial touch computer and industrial panel odm must have a strong ability to adapt to large temperature fluctuations. Through a series of wide-temperature operation detection methods such as controlled high-temperature tests and constant temperature and humidity tests, the performance stability of the equipment in extreme temperature environments can be deeply verified, and problems such as screen failure and system lag caused by temperature changes can be effectively avoided. In the research, development, and production process of Zhichun brand products, the temperature adaptation needs of different industries and scenarios are fully considered to ensure that the products can work reliably under various temperature conditions.
3.ESD Anti-Static Test
In the industrial environment, static electricity is like a hidden "killer", which is everywhere and difficult to prevent. If the anti-static ability of equipment such as industrial grade monitor and industrial touchscreen display is insufficient, it is very likely to cause interface failures, data transmission interruptions, and even component burnout. During the test, each interface of the equipment will undergo a 4KV static contact test, and then carefully check whether the interface can be normally powered on and whether the signal is stable without interference, so as to ensure that the equipment can operate safely and reliably in the industrial environment full of static risks. Zhichun's products have passed strict ESD anti-static tests to eliminate users' worries about static electricity.
4.Vibration and Horizontal Drop Test
During the long-distance transportation of equipment from the manufacturer to the use site, it is inevitable to encounter unexpected situations such as bumps and collisions; during daily use, accidental drops may also occur due to various reasons. Through the vibration test simulating the automobile transportation scenario and the horizontal drop test simulating accidental falling, the structural strength and impact resistance of products such as industrial touch computer and 17 inch industrial monitor can be accurately tested, and the damage risk during transportation and use can be greatly reduced. In the product design and production of the Zhichun, potential risks in transportation and use are fully considered, and the anti-vibration and drop capabilities of the products are improved by strengthening the structural design.
5.Power Consumption and 48-Hour Aging Test
A qualified piece of equipment such as industrial touch display and open frame panel pc must have stable power consumption performance and long-lasting operation capabilities. During the test, all equipment will be uniformly sent to the aging room for 48-hour non-stop power-on display. During this period, professional inspectors will record the power consumption data, screen display status, and system operation status of the equipment in real time. This not only can quickly screen out products with abnormal power consumption and unstable operation but also can expose potential hardware failures in advance, greatly reducing the production defect rate. Zhichun products have passed strict power consumption and aging tests to ensure the stability and reliability of the products in long-term use.
6.Basic Performance Test of Display Screen
As the core interactive component of equipment such as industrial touchscreen display and industrial all in one tablet PC, the quality of the screen's basic performance directly determines the user experience. The inspection content covers many aspects: whether the resolution meets the established standards, whether the picture can be displayed in full screen without any offset in the horizontal and vertical directions, whether the displayed picture has no afterimage, no flicker, and no color distortion, and at the same time, it is necessary to carefully check whether the black edges of the screen are symmetrical to ensure the perfect visual effect and display integrity. During the test, the desktop background image can be flexibly adjusted to intuitively and conveniently observe whether there are any abnormalities. The Zhichun strictly controls the basic performance of the display screen to provide users with a clear and stable display effect.
7.Interface Compatibility and Signal Test
Equipment such as industrial touch computer and industrial panel odm need to be connected to a variety of external devices and signal sources in actual use, so interface performance is crucial. The test content is extensive, including the data transmission speed and device recognition ability of the USB interface, the signal reception and picture output quality of the VGA and HDMI interfaces - requiring the terminal to quickly display automatically after receiving the signal, and the picture to be clear and smooth without stuttering; at the same time, the communication function of the COM port and the connection and recognition ability of the LPT printer port will be fully verified to ensure that each interface can perfectly meet the complex and diverse connection needs of the industrial scenario. The Zhichun brand keeps improving in interface design and testing to ensure the efficient connection between the equipment and various external devices.
8.Special Test for Touch Sensitivity
For equipment with touch functions such as industrial touchscreen display and 10mm Industrial Tablet PC, touch sensitivity directly affects the operation efficiency and user experience. During the test, professional desktop test software eGalax Touch is usually used. First, the equipment is subjected to touch cleaning and calibration operations, and then a touch pen is used to draw carefully along the diagonal of the screen to check whether the lines are continuous without breakpoints; at the same time, click on key positions such as the start bar in the lower left corner of the screen and the display hidden icon in the lower right corner to observe whether the touch response is timely without delay, so as to ensure accurate and smooth operation. The touch equipment of the Zhichun brand has passed strict touch sensitivity tests to bring users a sensitive and convenient operation experience.
9.In-Depth Test of LCD Screen Image Quality
LCD screen indicators like color reproduction and brightness uniformity are critical for industrial data reading and image recognition. Running DisplayX software, we sequentially test its color purity and uniformity when showing red, green, blue, white, and black—no color deviation or light leakage means qualification. We also conduct tapping, brightness, and grayscale tests to ensure image quality. Zhichun strictly controls LCD screen quality for high-quality industrial display effects.
The pre-delivery inspection of industrial equipment represented by the Zhichun brand of Chongchang Company can be called the "last solid line of defense" for products to enter the market. Through the strict inspection of the above series of routine items, it can not only discover product quality defects in a timely and accurate manner but also carefully screen out reliable equipment that meets industrial-grade standards and is suitable for complex scenarios for users, providing a solid guarantee for the smooth development of subsequent production and operations. Whether it is 19 inch Industrial Panel PC or products provided by Android touch all in one PC supplier, they have all gone through such a strict inspection process to ensure that they serve users with excellent quality.
