What factors affect the price of a 4.3-inch LCD screen?
The price of a 4.3-inch LCD screen ranges from tens to hundreds of yuan, and the difference is mainly determined by the following three core dimensions:
Category of influencing factors | Specific factors | Explanation of the Impact on Prices |
1. Product specifications and performance | Resolution | High resolution (such as 800 * 480) is more expensive than low resolution (such as 480 * 272). |
Display technology | IPS technology is superior to TN technology in terms of color and viewing angle, and the price is also higher. |
Brightness and operating temperature | Industrial grade parameters such as high brightness (>500 nits) or wide temperature (-30 ° C~80 ° C) will significantly increase costs. |
Touch function | Touching (especially capacitive) is more expensive than not, and the cost of integrated touch modules is higher than that of external devices. |
2. Market and Supply | Brand and Quality Level | Renowned original brands (such as Tianma) or industrial grade products, due to their reliability and consistency, are priced much higher than consumer grade or white label products |
Market supply and demand and size cutting efficiency | The supply and demand fluctuations in the entire LCD panel industry will be transmitted to all sizes. Due to the non mainstream size of 4.3 inches, cutting has low economic benefits and may increase in price due to stock shortages |
3. Procurement and additional costs | Purchase Quantity | Batch procurement can significantly reduce unit price. |
Interface and compatibility | Special or outdated interface protocols may be more expensive due to limited supply, but they can save overall system development costs. |
Service and Warranty | Providing additional services such as long-term warranty and technical support will increase the cost. |
Considering issues such as resolution and lifespan
Based on your previous questions, we can establish a coherent selection strategy:
Resolution determines basic cost: The resolution you previously cared about (such as 800 * 480) is one of the core price difference factors.
The lifespan is linked to the quality level: The "lifespan" you inquired about is directly related to the brand and quality level, as well as the operating temperature in the table. To pursue a long lifespan, it is necessary to pay higher prices for industrial grade and wide temperature screens.
Supplier brands correspond to different price ranges: the previously mentioned suppliers (Tianma, Guoxian, and other original manufacturers) provide high reliability screens at higher prices; Module suppliers on B2B platforms offer more price flexible options
How to make decisions and inquire about prices
When making specific inquiries or selections, it is recommended to clarify the requirements according to the following steps:
Define core requirements: First determine the four hard indicators of resolution, brightness, touch mode, and working temperature.
Distinguishing procurement stages:
Research and development samples: You can search for specific models (such as TM043NBH02) on e-commerce platforms to purchase, with transparent prices (such as about 28 yuan), but be careful to distinguish between original and compatible.
Batch procurement: directly contact brand manufacturers or large module suppliers, provide a demand list (including annual usage) to obtain a formal quotation.
Comprehensive evaluation of total cost: For the maintenance of old systems, choosing a screen with compatible interfaces can save huge secondary development costs, although the screen itself may be more expensive.
If you can provide specific application scenarios (such as industrial control, portable devices) and budget ranges, I can offer you more targeted selection analysis and suggestions for finding suppliers.
