Once upon a time, plasma was one of the most mainstream television imaging technologies, with the most outstanding display effect, but it has now been eliminated by the times. Although LCD technology has dominated the market and is constantly evolving, due to the underlying limitations, poor contrast and non-uniformity are still inevitable. As a result, OLEDs have emerged as plasma replacements that eliminate the need for backlighting, enable ultra-slim fuselage and even bend, and at the same time provide unparalleled image quality. However, only one LG manufacturer currently sticks to the OLED camp.
OLED TV market status
In the past season, the cheapest OLED TV is the LG 55EC9300, priced at 3,000 US dollars (about 18606 yuan), still higher than the mainstream LCD TV prices in the market. Of course, its contrast and black levels are better than LCD TVs. But even so, the average consumer cannot afford this price.
David VanderWaal, the senior director of LG Marketing, said this is normal and the company does not expect to sell a large number of OLED models in 2015. At the same time, LG does not expect OLED TV prices to be too low, otherwise it will affect the financial status of the company. Obviously, the average price of a 4K LCD TV with the same size is only one-third of that of OLED. This huge price gap is the reason that OLED TVs cannot be popularized at present, and consumers are not interested in OLED TVs.
The income is gradually increasing but the production cost is still a problem
Although the price is still not cheap, but low-end OLED TVs based on LG 55EC9300 still attracted some consumers, LG also said that through the introduction of low-end models, OLED product line profitability gradually increased. However, the next challenge is the large screen size, the manufacturing difficulties and high costs associated with 4K resolution.
Relatively low yield has always been one of the bottlenecks of OLED technology. At the same time, due to the high cost, manufacturers are afraid to enter. Samsung and Sony, which once launched OLED TVs, have also set aside their OLED plans and focused on 4K LCD TVs to achieve better image quality through improved technologies such as quantum dots and HDR. Of course, its image quality still cannot be compared with OLED.
Does OLED really not become plasma?
For the future of OLED TVs, industry commentary is mixed. Some think it is the future of television technology, and some think it will embark on the old path of plasma. Tim Alessi, LG's new product director, believes that comparing OLED to plasma is unfair, because the former is a new technology and has become a trend (for example, more and more mobile products start using flexible OLED screens). Of course, maybe OLED will eventually break through the problems of size, resolution, and cost, and it will enter the mass consumer market. Obviously, this will be costly.

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.
2: LCD on first line, second line or third line described in this intruction take section according to two black lines on LCD screen. Here it added for clarified purpose.
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.
