01. Display effect
The ultimate effect of the display device is the core selection criteria, and different display technologies must have some differences in the display effect.
02. Display brightness
Neither of the two stitching techniques needs to be worried. On the contrary, the small-pitch LED electronic screen, which is known for its high brightness, faces the problem of over-brightness-a major marketing technology level of the small-pitch LED display electronic screen is "low brightness." In contrast, the LCD screen is more appropriate in terms of brightness level, suitable for applications with large display screens. On the contrast index, the small-pitch LED is *, but from the demand side, the contrast of the two major technologies exceeds the need for real display and the human eye's resolution limit. This makes the contrast effect. The quality of the two technologies depends more on the optimization of the software than on the limit of the hardware.
03. Resolution (PPT) index
Although small-pitch LEDs have been making breakthroughs, they still cannot compete with LCD splicing screens. At present, only LCD screens can achieve 2K popularity on 55-inch units, and only LCD screens that have hope and can popularize 4K in the future. For small-pitch LED electronic screens, a higher pixel density means that the stability of the stability design has increased in geometric base. The pixel pitch has decreased by 50%, and the backplane density has to be increased by 4 times. This is why the small pitch LED has broken through the bottlenecks of 1.0, 0.8, and 0.6, but the real reason for the large number of applications is only products such as 3.0 / 2.5. In addition, it is worth reminding that LCD screens have the advantage of pixel density. "The actual value is not very clear. "Because users rarely demand that high pixel density.
04. Color range
The color range indicator is generally not the focus of mosaic wall products. In addition to the application scenarios such as radio and television, the mosaic wall market has never been harsh on the demand for color reproduction range. From a comparative perspective, small-pitch LEDs are natural products with a wide color gamut. Liquid crystal depends on what kind of light source is used.
05. Color resolution index
Refresh frequency is a key indicator to effectively suppress the flicker of the screen. The refresh frequency of the Led screen is generally very high, and most of the liquid crystals are at the level of 60-120Hz, which have exceeded the resolution limit of the human eye.
07. Point defect
Point defects refer to the probability of bad, bright, dark, and color channels in display devices. In this regard, LCD products can also be controlled to an excellent level. In contrast, effective control of point defects is the main technical difficulty of LED screens. First, especially as the pixel pitch decreases, the difficulty of control increases to a geometric base.
08. Element thickness
In terms of cell thickness, liquid crystals have inherent advantages, and they have been continuously optimizing and improving. Although small-pitch LED displays have now achieved hyperblogging, there is not much room for improvement in the future.
In terms of optical pollution and visual comfort, liquid crystal mainly refers to glare and high-frequency blue light, and small-pitch LEDs are over-bright and high-frequency blue light.
09. Consumables and display core life indicators
Mainly refers to the lamp beads of the LED display and the back plate, the LCD screen body and the light source. In this regard, the life advantage of the liquid crystal * is clear. The overall can reach 100,000 hours. The individual differences of the LED beads and the stability of the back plate The problem determines that the lifespan of individual splices of such products is significantly different, and individual units may need to be replaced soon.
10. Engineering cooling
Engineering heat dissipation is an inevitable requirement for long-term stable operation of large-size display systems. In this regard, LCDs have more significant advantages because of their low power consumption and low power density. Although small-pitch LEDs have the characteristics of low power density, but The overall power consumption will still be higher. At the same time, small-pitch LED products that require high heat dissipation also mean higher system noise.

05. Color resolution index
The color resolution index is the actual viewing experience of the color range on the contrast index, and represents the ability of the display screen to ultimately restore the color. There is no method to brighten the measurement of this index. However, as a whole, small-pitch LEDs rely on color and contrast. Double advantages must be the best technology.
Refresh frequency is a key indicator to effectively suppress the flicker of the screen. The refresh frequency of the Led screen is generally very high, and most of the liquid crystals are at the level of 60-120Hz, which have exceeded the resolution limit of the human eye.
