Як визначити, хороший РК-екран чи поганий:
1, brightness
Brightness is to determine the brightness of the LCD display product on the screen. If its brightness is too low, it will cause users to see clearly what is displayed on the screen if it is used in certain environments with strong light. The brightness should be high, but you should also choose according to your own needs. If it is used indoors, you don't need too high brightness.

2, support resolution
The resolution of the LCD screen is one of the very important parameters for its display effect. The level of resolution determines the sharpness of the displayed image, whether the screen is delicate or not. Generally, its resolution is very high. If the resolution is too low, do not buy it, otherwise the display effect is not ideal. For example, the resolution of the LCD screen is 19201080P, which is already very good.
3, input signal type
На даний момент РК-екрани на ринку зазвичай підтримують введення та виведення сигналу в кількох форматах, але є також багато неповноцінних продуктів, які підтримують лише одну функцію введення та виводу сигналу, тому перед покупкою обов’язково ознайомтеся з підтримуваним введенням сигналу. тип сигналу.
4, contrast
The contrast of the liquid crystal display shows the vividness of the color and the effect of the color. Under normal circumstances, the contrast of the liquid crystal display is 3000:1, which belongs to the liquid crystal splicing product with higher contrast in the liquid crystal splicing market. If the contrast is too low, it will lead to shortcomings such as not bright enough and not rich enough, so the contrast is better to be high.
5, splicing gap
Because the LCD screen is composed of multiple splicing panels. Therefore, there will be a certain splicing gap between each panel. Of course, the smaller the stitching gap, the better. If the splicing gap is too large, it will affect the visual effect. At present, the LCD screen has successfully controlled the splicing to the lowest 5.5mm in the industry to fully guarantee the integrity of the display screen.
