How to choose TV screen?

Posted on

The benefit of a television display, to a great extent, is because of the LCD screen. The current LCD screen accounts for about 80% of the cost of the entire TV. This is why people often say that buying LCD TVs is the reason for buying LCD screens. However, how many people know the type and quality of LCD screens? The author summarizes the four points. Interested friends come and find out!
1, soft screen, hard screen
Soft screens and hard screens, in addition to their physical differences, also appear in the display. For example, the popular IPS hard screen has obvious advantages in displaying sports programs. It is suitable for watching sports programs. Especially during the Olympics, IPS hard screen LCD TVs can bring clear and smooth viewing effects to consumers.




(Cool open 55A2 is a classic product with LCD hard screen)
For example, the 55A2 smart TV, which was recently released by Cool Open, uses LG's IPS hard screen. This screen has a wide angle of view, no trailing, etc., and supports MEMC dynamic image quality compensation, HDR decoding, etc., can give users Excellent viewing results.

Compared with hard screens, soft screens also have their own characteristics, mainly in terms of color, but in the face of increasingly sophisticated IPS hard screens, this advantage is not so obvious.

2, visible range

In addition to the dispute between hardware and software, LCD TV has an important indicator is the visual range. Indeed, if a television is placed in the living room and is only able to make it clear to the audience directly opposite, it is unqualified. After all, if the number of guests is more than one, the spectators sitting at the side cannot watch TV properly.

Today's LCD TVs are basically able to reach a 178-degree viewing range, but there are also a small number of products that have a relatively small visual range, and users need to pay attention when they purchase.

3, brightness

This is another important indicator of an LCD screen, and this indicator has once misled the user so that the user thinks that the higher the brightness, the better. In fact, too high brightness directly reduces the black and white contrast, while affecting the gray scale and color scale performance. Frankly speaking, what your eyes feel is that brightness is not the harmony and beauty of color, and too bright is easy to cause fatigue and damage the eyes.



The current LCD screens are maintained at a reasonable level of brightness and modified by other techniques. As mentioned above, this cool open 55A2, you can use 10bit HDR decoding, using high dynamic light for rendering, more brilliant than pure high brightness.

4, the bigger the better?

The TVs that users buy now are really getting bigger and bigger. From the early 32 to the 55 inch nowadays, the trend of bigger size is quite obvious. But does it really need to be so big? Everyone knows that watching TVs of various screen sizes has a reasonable viewing distance. Now that TV screens are getting bigger and bigger, the viewing distance hasn't changed much.



Therefore, the screen is not necessarily the bigger the better, if you look at the big screen at close range, it will easily cause the visual fatigue to double. Therefore, it is particularly important to select a TV that fits the size of the viewing distance. View distance and TV screen size options can participate in the picture above.

Power Meter Socket

Power Meter is a monitoring and testing instrument which determines the power consumption of a connected appliance and the cost of the electricity consumed.
Built-in 3.6V rechargeable Batteries ( . The purpose of the batteries is to store the total electricity and memory setting
Resetting
If an abnormal display appears or the buttons produce no response, the instrument must be reset. To do this,
press the RESET button.
Display Mode
Entire LCD can be displayed for about 1 minute and then it automatically gets into Model. To transfer from
one mode to the other, press the FUNCTION button.
Mode 1: Time/Watt/Cost Display Display duration(how long) this device connect to power source.LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which means after 24 hours, it will re-caculate. LCD on second line displays current power which ranges in 0.0W 〜 9999W. LCD on third line displays the current electricity costs which ranges in O.Ocost 〜 9999cost. It will keep on O.OOcost before setting rate without other figures.
Mode 2: Time/Cumulative electrical quantity Display Display duration(how long) this device connect to power source.
LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which
means after 24 hours, it will re-caculate. LCD on second line displays current cumulative electrical quantity which ranges in 0.000KWH 〜 9999KWH without other figures. LCD on third line displays"DAY"- "1 'Will be showed on numerical part(the other three figures will be showed at carry) which means it has cumulated electrical quantity for 24hours(one day). The rest can be done in the same manner untill the maximal cumulative time of 9999 days.
Mode 3: TimeA^bltage/Frequency Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays current voltage supply (v) which ranges in 0.0V 〜 9999V .LCD on third line displays current frequency (HZ) which ranges in 0.0HZ 〜 9999Hz without other figures.
Mode 4: Time/Current/Power Factor Display LCD on first line displays the same as Mode 1 dones.LCD on second line displays load current which ranges in 0.0000A 〜 9999A. LCD on third line displays current power factor which ranges in 0.00PF 〜 LOOPF without other figures.
Mode 5:Time/Minimum Power Display LCD on first line displays the same as Mode 1 dones. LCD on
second line displays the minimum power which ranges in 0.0W 〜 9999W. LCD on third line displays character of "Lo" without other figures.
Mode 6: Time/Maximal Power Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays the maximal power which ranges in 0.0W 〜 9999W. LCD on third line displays character of "Hi" without other figures.
Mode 7: Time/Price Display LCD on first line displays the same as Mode 1 dones. LCD on third line displays the cost which ranges in O.OOCOST/KWH 〜 99.99COST/KWH without other figures.
Overload Display: When the power socket connects the load over 3680W, LCD on second line displays the''OVERLOAD[ with booming noise to warn the users, (selectable choice)
Supplemental informations:
1: Except [OVERLOAD[ interface, LCD on first line display time in repitition within 24hours.

3. Mode 7 will directly occur while press down button "cost".
4. [UP"&"Down" are in no function under un-setting mode.
Setting Mode
1. Electricity price setting
After keeping COST button pressed lasting more than 3 seconds(LCD on third line display system defaults price, eg O.OOCOST/KWH ),the rendered content begins moving up and down which means that the device
has entered the setting mode. After that, press FUNCTION for swithing , then press "UP"and "DOWN" button again to set value which ranges in OO.OOCOST/KWH 〜 99.99COST/KWH. After setting all above, press COST to return to Mode7 or it will automatically return to Mode7 without any pressing after setting with data storage.
