TFT belongs to active matrix liquid crystal display, which is technically driven by "active matrix". The method is to use transistor electrodes made of thin film technology, and use scanning method to "actively pull" control the opening and closing of any display point. When the light source is irradiated, it first passes through the lower polarizing plate upward, and uses liquid crystal molecules to conduct light.

The utility model is provided with two groups of heat dissipation holes and two groups of heat dissipation fans. When the TFT screen is used, the heat generated by the TFT screen during use is dissipated in time through the two groups of heat dissipation holes, so that the use of the TFT screen is not easily affected, and the two groups of heat dissipation fans can rotate to make the heat dissipation effect inside the connection component box better, so that the service life of the TFT screen is not easily affected. However, the TFT screen is difficult to flexibly adjust in multiple angles and in all directions according to the user's usage needs. The position during use is single and fixed, the use is not flexible enough, and the practicality is poor.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a TFT screen with automatic heat dissipation effect is proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a mounting plate, a base, a movable arm, a connecting frame and an assembly head. The mounting plate can be used to fix the entire device at any position by bolts. The base can be freely rotated 360 degrees in a plane to flexibly adjust the orientation of the TFT screen. The movable arm, the connecting frame and the assembly head can be rotated and adjusted to adjust the front and rear extension distance and the overall lifting and lowering height of the TFT screen.

[0015] 2. The utility model is provided with a heat conducting sheet, a heat dissipating fan and a heat dissipating mesh slot. The heat conducting sheet can continuously exchange and dissipate the heat generated by the internal operation of the device with the outside world, and the hot air flow that is not exchanged in time will float upward due to its own physical characteristics and dissipate through the heat dissipating mesh slot, so that the device as a whole can automatically dissipate heat, avoiding the accumulation of internal heat, causing the device to be overheated and overloaded and thus damaged. The heat dissipating fan continuously inhales fresh air from the outside and blows it into the device, cooling the internal components while also accelerating the flow rate of hot and cold air, thereby greatly improving the heat dissipation performance;

[0016] 3. The utility model provides a fixing ring, a shock-absorbing rubber pad, a damping spring rod and a movable ring plate. When the fixed support is vibrated, the vibration force will be transmitted to the mounting plate and then further transmitted to the movable ring plate.

The vibration force that is not completely dissipated will continue to be transmitted to the fixing ring. The shock-absorbing rubber pad has high viscosity and high elasticity, and the interaction between rubber molecules will hinder the movement characteristics of the molecular chain, so that the shock-absorbing rubber pad itself forms a damping property, which performs secondary buffering on the remaining vibration force, maintains the stability of the fixed ring shape, and makes the overall installation connection part of the equipment effectively weaken and buffer the vibration force, avoids the shaking of the TFT screen caused by the transmission of vibration force, and greatly improves the stability of the installation and use of the TFT screen.

[0024] Furthermore, the mounting plate 1 can be used to fix the entire device at any position using bolts.

[0025] Furthermore, the base 2 can be freely rotated 360 degrees in a plane, so as to flexibly adjust the orientation of the TFT screen 9.

[0026] Furthermore, the movable arm 3, the connecting frame 4 and the assembly head 5 can be rotated and adjusted relative to each other, so as to adjust the front-to-back extension distance and the overall lifting and lowering height of the TFT screen 9.

The heat dissipation fan 8 continuously draws fresh air from the outside and blows it into the device, blowing and cooling the internal devices while , and can also speed up the flow rate of hot and cold air. When the fixed support is vibrated, the vibration force will be transmitted to the mounting plate 1, and then further transmitted to the movable ring plate 16. The movable ring plate 16 is forced to move upward and contract, squeezing the damping spring rod 15. The damping spring rod 15 uses the characteristics of its own damper to effectively buffer and brake the vibration force, and the vibration force that is not completely dissipated will continue to be transmitted to the fixed ring 13. Through the high viscosity and high elasticity of the shock-absorbing rubber pad 14 itself, and the interaction between rubber molecules will hinder the movement characteristics of the molecular chain, the shock-absorbing rubber pad 14 itself forms a damping property, which performs secondary buffering on the remaining vibration force, maintains the stability of the shape of the fixed ring 13, and makes the overall installation connection part of the equipment effectively weaken and buffer the vibration force, avoiding the shaking of the TFT screen 9 caused by the transmission of vibration force. This is the working principle of the TFT screen with automatic heat dissipation effect.
