What does active range array mean? What is a distance array, how to use it, and how to calculate it

i.e. active matrix. An LCD technology that uses memory elements called TFT (Thin Film Transistor) to create individual active pixels.

Amorphoustft and PolysiliconTFT.

The original meaning of matrix is the womb, the mother of the control center, and the place where life is conceived. Mathematically, a matrix is a two-dimensional data arranged vertically and horizontally**, which originally came from a square matrix composed of coefficients and constants of a system of equations. This concept was first proposed by the 19th-century British mathematician John Kelly.

The concept of matrix also has many applications in production practice, such as the matrix diagram method and the matrix card system for protecting personal accounts (proposed by Shenzhen Domain Lubo) and so on. The original meaning of "matrix" is also often applied, for example, the analog equipment responsible for switching control between the front-end source and the control line in the monitoring system is also called the matrix.

Usage. The hardware function and software function of the series of products correspond to each other, and it is necessary to find out the entry point for developing new products or improving old products.

Clarify the product quality characteristics that should be guaranteed and their relationship with the management agency or guarantee department, so as to make the quality assurance system more reliable.

Clarify the relationship between the quality characteristics of products, test and measurement items, and test and measurement instruments, and strive to strengthen the quality evaluation system or improve efficiency.

When there are a variety of undesirable phenomena in the production process, and they have several common causes, it is hoped to understand the relationship between these undesirable phenomena and their causes, and then eliminate these undesirable phenomena in one fell swoop.

When conducting multivariate analysis, researching where to start and how to collect data.

The design principles of STN and TFT are different, it is recommended to learn it systematically, and there are not many books on TFT. TN and STN can take a look at "Liquid Crystal Display Device Manufacturing Technology".

Passive Matrix Active Matrix.

To be precise, it should be passive matrix and active matrix, so you may understand that STN is talking about liquid crystal materials.

TFT is talking about switching elements.

The two are not on the same level.

The virtual currency matrix doesn't quite understand what it means. Virtual currencies generally refer to digital cryptocurrencies such as Bitcoin, Litecoin, Weimob Coin, Rite-Hite, and Dogecoin.

There are built-in amplifiers, and there are passive ones. There are not many crossovers, and they are generally external electronic crossovers.

The matrix is just a form of placement of speakers, and the matrix is to hang or stack several or dozens of speakers in a field shape, which is generally used in large squares and theaters and other places that need surface sound sources.

The difference between the two:

Adjacency matrix: is a matrix that represents the adjacency between vertices. Let g=(v,e) be a graph, where v=. The adjacency matrix of g is a square matrix of order n with the following properties:

For undirected graphs, the adjacency matrix must be symmetrical, and the main diagonal must be zero (only undirected simple graphs will be discussed here), the secondary diagonal is not necessarily 0, and the directed graph is not necessarily the same.

In an undirected graph, the degree of any vertex i is the sum of all the elements in column i, in a directed graph the degree of vertex i is the sum of all elements in row i, and the degree of in is the sum of all elements in column i.

The adjacency matrix method is used to represent the graph with a total of n 2 spaces, because the adjacency matrix of the undirected graph must have a symmetrical relationship, so only the data of the upper triangle or the lower triangle need to be stored except for the diagonal zero, so only n(n-1) 2 spaces are needed.

TFT (Thin Film Transistor) LCD is a type of active matrix type liquid crystal display (AM-LCD). LCD flat panel display, especially TFT-LCD, is currently the only display device that has fully caught up with and surpassed CRT in terms of comprehensive performance such as brightness, contrast, power consumption, life, volume and weight, etc., with excellent performance, good mass production characteristics, high degree of automation, low cost of raw materials, and broad development space, which will quickly become the mainstream product in the new century and is a bright spot in global economic growth in the 21st century.

It's a transistor liquid crystal display.
