LCD TVs are household appliances that are now used by every family. Its light and beautiful appearance and extraordinary visual experience make people love it. How much do you know about the details of LCD TVs? How much is it installed? What kind of size is right? The landlord below will introduce you to everyone.
LCD TV size how to buy
In order to determine the LCD TV height more scientifically, it is necessary to choose the size and viewing distance of a suitable room to select LCD TVs.
Under normal circumstances, the living room distance in the 97cm-162cm can buy 28-inch TV; 112cm-187cm distance can buy 32-inch TV; 134cm-224cm distance can choose 36-inch TV; 153cm-255cm distance can buy 42-inch TV; A distance of -280cm can be used to select a 46-inch TV; 183cm-305cm can be used to select a 50-inch TV; 220cm-367cm can be used to select a 60-inch TV. If you are in the bedroom, a 30-inch LCD TV is more appropriate.
The types of walls are mainly divided into brick walls, wood walls, decorative walls, glass walls, and marble walls. These walls have strict requirements on the size and spacing of screw holes. When installing wall-mounted LCD TVs, you should pay attention to different installation techniques depending on the type of wall:
1. Normal brick wall installation does not require special tools and processes. Just use a percussive drill (pay attention to the diameter of the drill bit) to make holes in the wall, then insert the plastic expansion tube, fix the product with screws, and hang it on the TV.
2. Wall panels Walls are divided into solid wood panels and gypsum board walls. As long as the solid wood board is 2cm thick, use a tapping screw to directly fill the circle. If it is a gypsum board wall, you need to use a utility knife to drill a hole (to the size of your finger) at the center of the fixed point, and then place a 2cm thick hole on the upper hole of the hanger. The long wooden slats allow the self-tapping screws to pass through the gypsum board and enter the wood slats during self-tapping, so that the force area is increased.
3, marble walls Marble walls are divided into marble and patterned marble. For the whole marble plate, use a glass drill. When using a glass drill, it must be drilled while watering the glass drill to prevent the glass drill from being burned. If the glass drill is difficult to drill through the wall, the impact drill can be used instead when it is drilled in half, but the impact drill must be placed in the drill file, otherwise it will crack the marble. After the hole is hit, the expansion screw can be installed until it is tight. For pattern marble, be careful when boring because the patterned marble itself has lines on it, and a slightly larger vibration force will cause cracks to expand.
4, behind the glass wall glass wall and wall. If the glass wall is behind a brick wall, after the selected location, the glass is used to drill and drill, while also need to drill water while drilling, the selected glass drill bit must be larger than the impact drill bit of the brick wall, and the glass hole is played well. Afterwards, use the impact drill to drill the brick wall inside. In order to prevent the glass from being crushed when the screw is on, it is better to use the large screw of the expansion tube as the filling ring. The thickness of the packing can be chosen to be slightly thicker than the glass, and then tighten the screws. If the back of the glass plate is a wall, only the glass holes need to be drilled with glass. The glass holes should be slightly larger. After the hole is drilled, they can be put into the ring and then tapped with the self-tapping screws. The selected tapping screws must be used. Thicker than the thickness of the glass + the thickness of the wood.

LCD TV wall mount height is generally how much
After confirming the size of the LCD TV, determining the TV mounting height is actually determining the mounting height of the TV wall. In simple terms, the center line of the TV's LCD screen is flush with the eyes of people sitting on it, and it is 10-20cm taller. It depends on the height of your sofa. The position of the TV is best to be 5-10cm lower than yours after you sit. This is an ideal height. More importantly, it can keep your eyes from fatigue during long-term viewing. LCD TV installation height can refer to the following data. (Note: The height range of the TV set is 1/3 - 2/5 of the total height of the TV wall. The TV width is generally about 1/4 of the TV wall)
1, the family wall can be maintained at 0.9-1.1 m 2, store suspension should be about 1.6 meters, wall-mounted should be about 1.3 meters 3, the hospital hall is suspended at about 1.6 meters 4, the ward wall should be about 1 meter, This is an ideal height.

Determine the LCD TV installation height, together to understand the next LCD TV wall mounting considerations (for friends who want to DIY wall-mounted LCD TV is very useful) ~
One, load-bearing wall
This is the first issue to be considered before installation. In some rural or old-style residential areas, the external walls of the houses are solid. The internal walls of the remaining compartments are all hollow. Wall-mounted TVs cannot be installed and can only be seen on the cabinets. , Or forced installation causes the TV to break off from the wall. In fact, the installation of wall-mounted TVs has strict requirements on the firmness of the walls. Therefore, before purchasing “wall-mounted†LCD TVs, everyone should inspect the cement structure of their homes. LCD TVs need to be wall-mounted and the walls must be solid brick, concrete, or their equivalent strength mounting surface. According to the national "LCD TV installation service standards," the installation points: the mounting surface load capacity should be guaranteed not less than 4 times the actual load of the TV, the TV should not be dumped when the front and rear tilt 10 degrees.
Second, the installation of different types of walls
The types of walls are mainly divided into brick walls, wood walls, decorative walls, glass walls, and marble walls. These walls have strict requirements on the size and spacing of screw holes. When installing wall-mounted LCD TVs, you should pay attention to different installation techniques depending on the type of wall:
1. Normal brick wall installation does not require special tools and processes. Just use a percussive drill (pay attention to the diameter of the drill bit) to make holes in the wall, then insert the plastic expansion tube, fix the product with screws, and hang it on the TV.

If it is a gypsum board wall, you need to use a utility knife to drill a hole (to the size of your finger) at the center of the fixed point, and then place a 2cm thick hole on the upper hole of the hanger. The long wooden slats allow the self-tapping screws to pass through the gypsum board and enter the wood slats during self-tapping, so that the force area is increased.
3, marble walls Marble walls are divided into marble and patterned marble. For the whole marble plate, use a glass drill. When using a glass drill, it must be drilled while watering the glass drill to prevent the glass drill from being burned. If the glass drill is difficult to drill through the wall, the impact drill can be used instead when it is drilled in half, but the impact drill must be placed in the drill file, otherwise it will crack the marble. After the hole is hit, the expansion screw can be installed until it is tight. For pattern marble, be careful when boring because the patterned marble itself has lines on it, and a slightly larger vibration force will cause cracks to expand.
4, behind the glass wall glass wall and wall. If the glass wall is behind a brick wall, after the selected location, the glass is used to drill and drill, while also need to drill water while drilling, the selected glass drill bit must be larger than the impact drill bit of the brick wall, and the glass hole is played well. Afterwards, use the impact drill to drill the brick wall inside. In order to prevent the glass from being crushed when the screw is on, it is better to use the large screw of the expansion tube as the filling ring. The thickness of the packing can be chosen to be slightly thicker than the glass, and then tighten the screws. If the back of the glass plate is a wall, only the glass holes need to be drilled with glass. The glass holes should be slightly larger. After the hole is drilled, they can be put into the ring and then tapped with the self-tapping screws. The selected tapping screws must be used. Thicker than the thickness of the glass + the thickness of the wood.
Third, LCD TV wall installation considerations
1. Accurately locate the mounting position of the LCD TV on the mounting surface. The positioning accuracy must be ensured and the mounting surface is fixed. 2. In general LCD TVs, the heat dissipation grid is usually designed on the back or on the side of the back. Therefore, the back of the TV and the four sides of the TV need a ventilation and heat dissipation space. The distance between the wall-mounted TV and the wall should be about 15 cm.
3, because the TV's various interfaces are basically arranged on the back, a variety of data lines can not withstand the wall 5 points bend, otherwise it is easy to break.
4, the installation process should be careful, when moving the whole machine should be gently, and bedding should be prepared to prevent scratching the display.
5, according to the requirements of the rack installation instructions, follow the steps to install.
6. If the display screen has connections with the speaker and mounting bracket, attention must be paid to distinguish between left and right sides and positive and negative sides.
7. If you need to connect the speaker cable, you should pay attention to the positive and negative polarity of the speaker cable to prevent the sound of the left and right channel inversion.
8. After the display is hung, it needs to be measured with a level ruler, adjust the pylon screws so that the display screen is completely in the horizontal position, and the panning error of the entire LCD TV installed position should be less than 1cm, and the left and right tilt error is less than 1 degree.
9, the power line should be installed on the air switch and other protection devices, should not change the length of the power line and signal line. It must be lengthened or changed. Cables that meet the requirements should be used.
