How to choose LED electronic display and LCD screen?
1, from the display effect comparison, the final effect of the display device is the most core selection specification, and different display technology in the display effect above there must be some differences.
2, from the brightness, both splicing technology do not have to worry about not enough. Instead, the small pitch LED electronic display screen known for high brightness is facing the problem of over-brightness. Small pitch LED electronic display screen is a main technology is low brightness “compared to the LCD display in the brightness level above seems more appropriate, suitable for the application of large display screen. Contrast index above, small pitch led highest but from the demand side, the contrast of the two major technologies are beyond the actual display needs and human eye resolution limit. This makes the contrast effect, the two technology picture more depends on the optimization of the software, rather than the limit value of the hardware.
3, resolution (PPI indicators, although the small spacing led has been in the breakthrough, but still not able to compete with the LCD splicing screen, currently in the 55-inch unit can realize the popularity of 2K only LCD screen, the future has the hope and can popularize the 4K more only LCD screen. For small pitch LED electronic display, higher pixel density means stability of the design of the difficulty of geometric growth, pixel pitch down 50% backplane density will have to improve 4 times, this is why small pitch LED has broken through the 1.00.8 and 0.6 bottleneck, but the real application of a large number of only 3.0/2.5 products such as the fundamental reason for this In addition, it is worthwhile to Reminder of the LCD screen has the advantage of pixel density of the actual value is not very clear “because the user rarely demand so high pixel density.
4, the color range of this indicator is generally not the most concerned about the direction of the splicing wall products, in addition to broadcasting and other applications such as more attention, the demand for color reproduction range, splicing wall market has never been harsh. From a comparative point of view, small spacing LED electronic display is a natural wide color gamut products. Liquid crystal depends on what kind of light source is used.
5, color resolution index is the color range in the contrast index of the actual viewing experience, on behalf of the display screen ultimately restore the color of the ability to determine this indicator there is no quantitative method, but on the whole, small spacing led with the double advantage of color and contrast, must be the best technology.
6,Refresh frequency is the key indicator to effectively inhibit the flickering feeling of the screen picture. the LED electronic display refresh frequency is generally very high, most of the LCD is 60-120Hz level, have exceeded the human eye's resolution limit.
7, point defect refers to the display device appears bad point, bright spot, dark point and color channel probability, this aspect of the liquid crystal products can also be controlled to a very good level, compared to the effective control of point defect is one of the main technical difficulties of the LED electronic display, especially with the pixel pitch of the narrowing of the control of the difficulty of geometric growth.
8, unit thickness, liquid crystal has an inherent advantage, and has been optimized from time to time, but also has been in progress. Small spacing LED electronic display screen has been realized although ultra-thin, but the future progress of the space will not be too big. Optical pollution and visual comfort, liquid crystal mainly refers to glare and high frequency blue light, small pitch led is too bright and high frequency blue light problem.
9, consumables and display core life indicators, mainly refers to the LED electronic display lamp beads and backplane, LCD screen and light source, this aspect of the life of the liquid crystal advantage is most clear, the overall can reach 100,000 hours, LED electronic display lamp beads individual differences and the stability of the backplane problem determines the life of such products between the individual splicing body life difference is more significant, individual units may soon need to be replaced.
10, engineering heat dissipation is a large size display system temporary stability requirements, in this regard, liquid crystal because of its low power consumption and low power density, the advantage is more significant, small spacing led although the characteristics of low power density, but the overall power consumption will still be higher, at the same time, the heat dissipation requirements of the small spacing LED electronic display products also means that the system noise to be higher.
