Description

Technical Field

[0001] The utility model belongs to the field of electronic products, and in particular relates to an LCD liquid crystal display screen with an anti-static function. Background Art

[0002] With the development of display technology, touch screens are increasingly widely used in various devices with display functions. LCD screens, as the main display devices, are widely used in many fields such as national defense, industry, home use, and public facilities. At present, the requirements for displays are getting higher and higher, and they need to be as small as possible, with a wide operating temperature range, low power consumption, and a wide viewing angle to display various texts. Traditional LCD displays use an SMT structure and need to connect controller ICs, memory ICs, driver ICs, DC / DC power conversion circuit ICs, bias circuits, temperature compensation circuits, etc.

[0003] During use, since the display screen circuit components are too concentrated, the display screen is very easy to accumulate charges and generate static electricity in the installation frame. The static electricity voltage will form a large static electricity induction electric field between the LCD screen and the frame, and the arrangement state of the liquid crystal will change under the action of the static electricity induction electric field, resulting in abnormal display of pen segments (i.e. static electricity display), and even damage to the LCD screen. When the display screen is in a suspended state in the outside world, such as a large-size display screen used for hanging in a large evening party, the static electricity voltage generated inside it will be higher and because it is in a suspended state, it is difficult for the operator to eliminate the internal static electricity in time. Therefore, an LCD screen with anti-static function is proposed to solve the above problems. Utility Model Content

[0022] Example

[0023] Depend on Figure 1-5 Provided is an LCD display screen with anti-static function, comprising a display screen 1 and a mounting frame 2, wherein the display screen 1 is embedded in the mounting frame 2;

[0024] Two lifting assemblies 3 are vertically mounted in the mounting frame 2. The two lifting assemblies 3 each include a vertically arranged threaded screw 34. A mounting block 36 is slidably arranged on the threaded screw 34.

[0025] An electrostatic elimination component 4 is provided on one side of each of the two groups of lifting components 3. The electrostatic elimination component 4 includes a high-voltage generator 41 fixed to the side of the lifting component 3. A power cord 43 is connected to the output end of the high-voltage generator 41. A mounting seat 44 is connected to the extended end of the power cord 43. The mounting seat 44 is fixed to the side surface of the mounting block 36 and moves up and down with the mounting block 36. A discharge electrode rod 45 is carried on the upper end surface of the mounting seat 44. The power cord 43 passes through the mounting seat 44 and is electrically connected to the discharge electrode rod 45.

[0026] In this embodiment, by coordinating the movements between the static elimination component 4 and the lifting component 3, the high-voltage generator 41 is powered on, so that the tip of the discharge electrode 45 generates a high-voltage corona under the electrical transmission of the power cord 43 and discharges through the end, and the air in the mounting frame 2 is ionized into a large number of positive and negative ions through ionization conduction. The two sets of lifting components 3 are used to lift and drive the static elimination component 4, so that the discharge electrode 45 set on the two sets of static elimination components 4 can ionize a large range of air in the mounting frame 2 and ionize it into positive and negative ions. Subsequently, by controlling the motor drive of the fan 5, a large number of positive and negative ions are blown to the back of the display screen 1 by the wind blowing of the fan 5, thereby achieving neutralization and elimination of the static electricity generated by the display screen 1. The static elimination component 4 is used to quickly eliminate the static electricity generated between the display screen 1 and the mounting frame 2. At the same time, the operation is simple. The driving of the static elimination component 4 by the lifting component 3 has a large coverage area for static neutralization and elimination.

[0027] Specifically, refer to Figure 1 , Figure 2A fan 5 is provided between the two lifting components 3. The fan 5 is fixed to the inner bottom wall of the mounting frame 2. The fan 5 includes a motor for driving and a plurality of blades. The bottom wall of the mounting frame 2 is provided with an air inlet which is arranged corresponding to the blades of the fan 5.

[0028] In this embodiment, after the discharge electrode rods 45 on the two sets of static elimination components 4 ionize a large range of air in the mounting frame 2 and ionize it into positive and negative ions, by controlling the motor drive of the fan 5, a large number of positive and negative ions are blown to the back of the display screen 1 by the wind force of the fan 5, thereby achieving the neutralization and elimination of the static electricity generated by the display screen 1.

[0029] Specifically, refer to Figures 1 to 4 Both lifting assemblies 3 include a base plate 31 disposed on the side wall of the mounting frame 2, a motor seat 32 is fixedly disposed on the upper end surface of the base plate 31, a reciprocating motor 33 is fixedly disposed inside the motor seat 32, and an output end of the reciprocating motor 33 passes through the motor seat 32 and is connected to the bottom of the threaded screw 34.

[0030] In this embodiment, by connecting the reciprocating motor 33 to a power source and controlling its power output value, the reciprocating motor 33 drives the threaded screw 34 to rotate. Under the limitation of the side limit rods 38 on both sides, the set sliding sleeve 35 can rise or fall linearly within the travel range of the threaded screw 34.

[0031] Specifically, refer to Figures 1 to 4 A sliding sleeve 35 is meshed and slidably provided on the threaded screw 34, and the mounting block 36 surrounds the sliding sleeve 35 and is fixedly connected to it. A side limit rod 38 is erected on both sides of the bottom plate 31, and the limit rods 38 on both sides extend through both sides of the mounting block 36. The limit rods 38 on both sides and the top of the threaded screw 34 jointly support a top plate 37, and the end of the threaded screw 34 rotates in the top plate 37 through a bearing.

[0032] In this embodiment, when the threaded screw 34 is rotating, the side limit rods 38 arranged on both sides of the threaded screw 34 are limited, so that the set mounting block 36 can rise or fall linearly within the travel range of the threaded screw 34. The side limit rods 38 limit the mounting block 36, thereby avoiding the problem that the mounting block 36 rotates on the threaded screw 34 and cannot be raised or lowered.

[0033] Specifically, refer to Figures 1 to 5 The high voltage generator 41 is fixed to one side of the motor base 32 , and the output end of the high voltage generator 41 has two electrode connectors 42 , which are respectively positive and negative electrode connectors.

[0034] In this embodiment, by connecting the high voltage generator 41 to the power supply, a high voltage corona is generated at the tip of the discharge electrode 45 under the electrical transmission of the two electrode connectors 42 and the power cord 43, and discharge is performed through the end, and the air in the mounting frame 2 is ionized into a large number of positive and negative ions through ionization conduction. The high voltage generator 41 and the discharge electrode 45 are both existing mature structures, and the model of the discharge electrode 45 is the SJ-E series hybrid ultra-high-speed induction static eliminator.

[0035] Specifically, refer to Figures 1 to 5 The two electrode connectors 42 are electrically connected to a power line 43 .

[0036] In this embodiment, the power line 43 can be used for electrical transmission and enable the discharge electrode 45 electrically connected thereto to generate high voltage corona.

[0037] The LCD display screen with anti-static function of the utility model:

[0038] Step 1: When the user performs static elimination on the display screen, the reciprocating motor 33 is connected to a power source and its power output value is controlled, so that the reciprocating motor 33 drives the threaded screw 34 to rotate. Under the limitation of the side limiting rods 38 on both sides, the set sliding sleeve 35 can be linearly raised or lowered within the stroke range of the threaded screw 34, thereby driving the mounting block 36 surrounded by the sliding sleeve 35 to rise or fall. By fixing the mounting seat 44 on one side of the mounting block 36, the mounting seat 44 that follows the movement finally drives the discharge electrode rod 45 to rise or fall linearly within the mounting frame 2;

[0039] Step 2: By connecting the power supply to the high-voltage generator 41, a high-voltage corona is generated at the tip of the discharge electrode 45 under the electrical transmission of the two electrode connectors 42 and the power line 43, and discharges through the end, and the air in the mounting frame 2 is ionized into a large number of positive and negative ions through ionization conduction, and the two sets of lifting components 3 are coordinated to drive the lifting of the static elimination component 4, so that the discharge electrode 45 set on the two sets of static elimination components 4 can ionize a large range of air in the mounting frame 2 and ionize it into positive and negative ions, and then by controlling the motor drive of the fan 5, a large number of positive and negative ions are blown to the back of the display screen 1 by the wind blowing of the fan 5, thereby achieving the neutralization and elimination of the static electricity generated by the display screen 1.
