On Mode Power Consumption

Nominal Conditions: On Mode Power Consumption [W] Amount of power required to operate the product, measured in the active-use “On” mode 22.7
Nominal Conditions: On Mode Average Power per Screen Size [W/cm2] TV efficiency, defined as the average amount of power consumed per square centimeter of the screen size A lower value means higher efficiency 0.0345
Nominal Conditions: Maximum On Mode Power [W] Maximum amount of power required to operate the product when the product’s volume and brightness are set at maximum levels 25
Over-Voltage Conditions: On Mode Power Consumption [W] Measured during voltage fluctuation conditions, eg during battery charging and discharging cycles Product is tested with an increased voltage (15% increase from the manufacturer’s rated input voltage) 22.1
Under-Voltage Conditions: On Mode Power Consumption [W] Measured during voltage fluctuation conditions, eg during battery charging and discharging cycles Product is tested with a decreased voltage (15% decrease from the manufacturer’s rated input voltage) 21.8
Post Environment: On Mode Power Consumption [W] Measured after the product is exposed to 40°C ± 2°C temperature and 93% ± 3% relative humidity for a minimum of 24 hours, replicating environmental factors that off-grid products are typically used in 23.2

Standby Mode Power Consumption

Nominal Conditions: Standby Mode Power Consumption [W] Amount of power required when the product is on standby mode (when it is plugged in but turned off) 0.22
Over-Voltage Conditions: Standby Mode Power Consumption [W] Amount of power required when the product is on standby mode, measured in over-voltage conditions (15% increase of rated input voltage) 0.22
Under-Voltage Conditions: Standby Mode Power Consumption [W] Amount of power required when the product is on standby mode, measured in under-voltage conditions (15% decrease of rated input voltage) 0.22
Post Environment: Standby Mode Power Consumption [W] Amount of power required when the product is on standby mode, measured after 24 hours of environmental exposure 0.22

Luminance

Luminance Home Picture Mode [Cd/m2] Brightness of display in “Home Picture” modes; Larger values mean brighter 209
Luminance Retail Picture Mode [Cd/m2] Brightness of display in “Retail Picture” modes; Larger values mean brighter 211

Viewing Angle

Horizontal Viewing Angle [degree], tested at 1/2 luminance Angle at which users can still view the display clearly and an indication of the display quality 90
Horizontal Viewing Angle [degree], tested at 1/10 luminance Angle at which users can still view the display clearly and an indication of the display quality 134
Vertical Viewing Angle [degree], tested at 1/2 luminance Angle at which users can still view the display clearly and an indication of the display quality 63
Vertical Viewing Angle [degree], tested at 1/10 luminance Angle at which users can still view the display clearly and an indication of the display quality 123

Ingress Protection

Ingress Protection Rating [IP number] Rates the effectiveness of the sealing of electrical enclosures against intrusion from foreign bodies (eg fingers, tools, dirt, etc) IP20

Connectivity

Product Quality Inspection

Is the TV of good build quality and free of any visible defects? Yes
Notes About Quality N/A
Is the TV clearly marked with a standard nameplate? Yes
Notes About Nameplate N/A
Does the TV's packaging include appropriate information? No
Notes About Packaging No weight, package dimension, or date of manufacture info on packaging
Does the TV come with appropriate documentation? No
Notes About Documentation No quality assurance certificate or warranty info included. User manual supplied is incorrect for the sample TV.

Off-Grid Compatibility

Is the TV able to function properly during and after the voltage fluctuation test? Yes
Notes About Voltage Fluctuation Test N/A
Does the TV have its own low voltage disconnect (LVD) & reconnect (LVR) circuit or similar automatic shutdown mechanism to protect batteries from unintended drainage? Yes
Notes About LVD and LVR Test As the voltage reduced the sound went off at 10.0 volts and the picture disappeared at 6.8 volts and Standby mode was entered at 5.1 volts. When the voltage was increased, the set would come out of standby and function normally when 10.2 volts was reached. This was considered to be a correctly operating LVD/LVR function.
Does the TV have a timer function which enables automatic shutdown after a set period of time? Yes
Is the LVD/LVR/timer function adequately described in the user manual or product packaging? No
Does the TV have any power saving features? Auto Sleep
