What are the important technical parameters of liquid crystal display module to know?

The liquid crystal display # 1.5 LCD display # module appears on the screen # 24 pin LCD # of our common electronic products. It has the advantages of environmental protection, low energy consumption, low noise, and low heat generation. So what are the important parameters of the liquid crystal display # 1.5inch TFT # module?

1. Resolution is a very important indicator in the display # 1.77 inches touch LCD module # module, which determines the clarity of information display # 39 pin TFT LCD display# to a certain extent. Specifically, it refers to the number of dots that can be displayed in the horizontal and vertical directions of the screen # 1.77 inch 128x160 spi full color TFT LCD display #. The more dots, the higher the resolution, and the more content displayed on the same screen # display LCD TFT #.

2. Contrast Accessories such as control ICs, filters, and orientation films used in the manufacture of LCD panels are related to the contrast ratio of the panel. If it is a screen # white LCD display screen # application in the general field, the contrast ratio should reach 350:1, but the contrast ratio of a better CRT display # display LCD custom # is generally in 500:1 or more.

3. BrightnessThis is easy to understand. Liquid crystal is a substance between a solid state and a liquid state. It does not emit light by itself. It needs an additional light source to emit light. The number of lamps generally determines the brightness. However, the difference in arrangement will also affect the visual effect. For example, the current manufacturer will use a "U" shape to place one lamp, so that three can reach the effect of six.

4. Viewing angleThe wide viewing angle means that when you look at the screen from any direction, the information displayed on the screen # 1.77inch TFT# can be more clearly displayed # mcu module #, otherwise, only a few directions can see the screen# 2 inch square touch screen modul # content clearly.

5. Signal response timeThe response time is divided into two parts: "rise time" and "fall time", and the response time usually referred to refers to the sum of the two, that is, the response time of the liquid crystal from dark to bright or from bright to dark, usually in milliseconds. (ms) is the unit. For the display # tft screen with mcu # module, when the response time is less than 40ms, there will be obvious "smearing" or "afterimage" phenomenon. If it can reach 60 frames per second, the image can be smooth.
