When it comes to current TV display technology, I believe many of my friends will think of OLED and 8K display technology. Because of these two TV display technologies, they have very outstanding performance in terms of picture quality, and often cause many consumers to compare these two technologies. Some people think that OLED TVs are more outstanding, and others think that the quality of 8K TVs is more clear. From the point of view of the development trend of the color TV market today, what challenges are needed to overcome the future popularity of OLED TVs and 8K TVs?
First of all, let's take a look at OLED TV. According to the author's understanding, OLEDs are organic light-emitting diodes, also known as organic light-emitting diodes. OLED TVs, unlike our current common LCD TVs and Quantum-dot TVs, can emit light independently for each pixel. This eliminates the need for color filters, liquid crystals, and polarizers, just like ordinary LCD TVs. With such complicated structures, the body is also more lightweight.
From the aspect of picture quality performance, OLED TVs are stronger than LCD TVs in light and dark contrast compared to traditional LCD TVs. Since each pixel of the OLED TV can be turned on and off by itself, almost no black display can be achieved without light emission. At the same time, in terms of color, OLED TVs also have a good performance. The reason of its own luminescence characteristics makes it have a higher degree of reduction.
However, OLED TVs are also facing many difficult problems to overcome, such as high prices, service life, low production frequency and other issues, making OLED TVs not truly universal. From the current point of view, the OLED TV market is still facing the phenomenon of insufficient supply of the panel. The not yet fully developed industrial chain has restricted the further popularization of OLED. It is not only time for OLED to become the "standard" for future television, but also requires technological advancement. From the current point of view, these problems still exist.
Let's look at 8K TV again. The 8K TV has an 8K resolution TV, which can be 4 times the 4K resolution and 16 times the 1080P. 8K resolution pixels can reach 33 million, enough to achieve 4.3 times of human eye recognition, from 4K to 8K, the realization is not the increase of clarity, 8K TV in picture precision, color gamut coverage, color depth, frame Speed ​​and other aspects have improved.
However, 8K TV has a lot of problems in terms of film sources. There is no difference between television without program source and ordinary TV. At the same time, the selling price is also a big problem. The 4K TVs that Sony and LG launched in 2012 are 84 inches in size, and the price is as high as 100,000. If it is 8K TV, the price is definitely higher.
More generally speaking, 8K TV seems to be only a concept now. The arrival of an 8K era is not the birth of an 8K TV but the creation of an 8K industrial chain ecosystem. In the situation where 4K TV is not yet fully popular, it may be premature to talk about the popularization of 8K TV.
However, with the development of TV quality, 4K definitely will not be the end point. The arrival of 8K TV is an inevitable trend. Just like smartphones, 1080P has been able to satisfy the eyes of most people. Many large manufacturers including Samsung will The screen resolution of the mobile phone has been raised to 2K, and even Sony has gone straight to 4K. This is not paranoid but the normal trajectory of technological development.
Dc gear motor, namely gear reduction motor, is based on ordinary Dc Motor, coupled with gear reduction gearbox.
The gear reducer is used to provide low speed and large torque.
At the same time, the gearbox with different deceleration ratio can provide different speed and torque.
Generally different industries, using different power dc motor, generally adopt custom parameter design pattern.
What are the four ratings of the Dc Gear Motor? The DC gear motor is often seen in our industrial production. Here Shunchang Motor gives you the knowledge of its four ratings. To talk about
1. Rated Current: The rated current is the maximum current allowed to flow through the armature winding of the DC deceleration motor in accordance with the specified operating mode, in A.
2. Rated Voltage: The rated voltage is the maximum additional voltage that the armature winding of the motor can work safely, unit V. It
3. Rated Speed: Rated speed refers to the rotational speed of the Gear Reducer Motor in the rated voltage, rated current and output rated power under the circumstances of operation, the unit is r/min. Such
4, rated power: rated power refers to the motor in accordance with the specified mode of operation can provide output power. For motor, rated power is the output of mechanical power on the shaft.
precision instruments and meters,automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows,etc., wide application range
Features: gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
