[0019] Please refer to Figures 1 to 3 , the present utility model discloses a liquid crystal display screen with high brightness and strong antistatic ability, which comprises:

[0020] a liquid crystal panel 1 and a backlight module 2,

[0021] The backlight module 2 is disposed on the lower side of the liquid crystal panel 1. The backlight module 2 includes a brightness enhancement film 21 and a light-emitting component 22, and the brightness enhancement film 21 is attached to the front surface of the light-emitting component 22;

[0022] The liquid crystal panel 1 includes a low-impedance sheet 11, an electrostatic film 12, a liquid crystal component 13 and a brightness enhancement sheet 14. The electrostatic film 12 is coated on the front surface of the liquid crystal component 13, the low-impedance sheet 11 is attached to the front surface of the liquid crystal component 13, and the brightness enhancement sheet 14 is attached to the back surface of the liquid crystal component 13. The liquid crystal panel 1 is used to control the liquid crystal particles of the corresponding pixels in the liquid crystal component 13 to store or release charges so that the light emitted by the backlight module 2 can pass through or be blocked.

[0023] In the present utility model, a low-impedance sheet 11, an electrostatic film 12 and a brightness enhancement sheet 14 are disposed on the liquid crystal component 13. The electrostatic film 12 is coated on the front surface of the liquid crystal component 13, the low-impedance sheet 11 is attached to the front surface of the liquid crystal component 13, and the brightness enhancement sheet 14 is attached to the back surface of the liquid crystal component 13 to form the liquid crystal panel 1. Cooperating with the backlight module 2 formed by the light-emitting component 22 provided with the brightness enhancement film 21, the liquid crystal panel 1 controls the liquid crystal particles of the corresponding pixels in the liquid crystal component 13 to store or release charges so that the light emitted by the backlight module 2 can pass through or be blocked to realize the display of the liquid crystal display screen. The low-impedance sheet 11 can accelerate the release of static electricity, the electrostatic film 12 can reduce the influence of static electricity on the liquid crystal component 13, and the brightness enhancement sheet 14 and the brightness enhancement film 21 can respectively improve the brightness of the liquid crystal panel 1 and the backlight module 2, thereby effectively improving the brightness and antistatic ability of the liquid crystal display screen, enabling the display device equipped with the liquid crystal display screen to work under strong static electricity and high-brightness environmental conditions.

[0024] Refer to Figures 1 to 3 , the liquid crystal component 13 includes a first glass substrate 131, a color filter 132, a liquid crystal layer 133 and a second glass substrate 134. A conductive layer is provided on the front surface of the second glass substrate 134.

The color filter 132 is attached to the front surface of the liquid crystal layer 133, and the first glass substrate 131 covers the upper side of the color filter 132.

[0025] Specifically, the first glass substrate 131 and the second glass substrate 134 serve as the main body of the entire liquid crystal module 13. A conductive layer is formed on the second glass substrate 134 as the base material. In this embodiment, the conductive layer is an ITO transparent conductive layer, which includes pixel electrodes (P electrodes) and common electrodes (M electrodes), responsible for providing a conductive path for the liquid crystal layer 133, but is not limited thereto.

[0026] Specifically, in this embodiment, the liquid crystal display screen is a TFT-LCD screen, which uses thin film transistors (TFTs) as control elements. By controlling the storage or release of charges of the liquid crystal particles of each pixel, it controls the transmission or blocking of light, enabling the liquid crystal layer 133 to jointly determine the arrangement and polarization state of its pixels through electric force and elastic force. When no charge passes through the liquid crystal particles, the liquid crystal molecules block the light transmission, and the corresponding pixel is displayed as black. When a charge passes through the liquid crystal particles, the liquid crystal molecules allow the light to pass through, and the corresponding pixel is displayed as bright, thereby realizing the function of liquid crystal display.

[0027] Specifically, in this embodiment, the light deflected by the liquid crystal molecules can only display different gray levels and cannot provide the three primary colors of red, green, and blue (RGB). Therefore, a color filter 132 composed of three RGB filters is also provided to mix and adjust the color and brightness of each pixel point through the three filters, but is not limited thereto.

[0028] Specifically, in this embodiment, based on the above liquid crystal module 13, an IPS static electricity film (static electricity film 12) is plated on the front surface of the liquid crystal module 13 to achieve the coating protection of the liquid crystal module 13, prevent static electricity from penetrating into the interior of the liquid crystal module 13, protect the materials and electrodes inside the liquid crystal module 13, and enable the antistatic ability of the liquid crystal display screen to reach 15 KV; and a low-impedance polarizing film (low-impedance film 11) and a brightness-enhancing polarizing film (brightness-enhancing film 14) attached to the front and back surfaces of the liquid crystal module 13 respectively are polarizing films, which can control the light to pass through in a single direction to improve the brightness of the display screen and can accelerate the static electricity release of the display screen.

[0029] Refer to Figures 1 to 3 , the brightness-enhancing film 21 includes a first light condensing sheet 211 and a second light condensing sheet 212. The second light condensing sheet 212 is attached to the front surface of the light-emitting component 22, and the first light condensing sheet 211 is attached to the front surface of the second light condensing sheet 212.

[0030] Specifically, in this embodiment, the first light condensing sheet 211 and the second light condensing sheet 212 are prism sheets, which are thin films capable of gathering the light emitted by the light-emitting component 22, and are beneficial to improving the light-emitting efficiency of the entire backlight module 2, but are not limited thereto.

[0031] Refer to Figures 1 to 3, the light-emitting component 22 includes a diffusion film 221, a light guide plate 222, a reflective film 223, and a plurality of LED lights 224 arranged in an array. The diffusion film 221 and the reflective film 223 are respectively attached to the front and back of the light guide plate 222, and the light guide plate 222 covers the upper side of the plurality of LED lights 224.

[0032] Specifically, in this embodiment, the LED lights 224 are used to provide light sources, the light guide plate 222 is used to conduct the light emitted by the LED lights 224, and the diffusion film 221 is responsible for correcting the propagation direction of the light emitted from the light guide plate 222, so that the liquid crystal screen has uniform and soft optical characteristics. The reflective film 223 is responsible for reflecting the light escaping from the light guide plate 222 back to the light guide plate 222 to improve the utilization rate of the light emitted by the LED lights 224, but is not limited thereto.

[0033] Refer to Figures 1 to 3 , the liquid crystal display screen further includes an FPC module 3. The FPC module 3 is electrically connected to the liquid crystal panel 1 and the backlight module 2 respectively, and a bent area 31 with a grid copper plating treatment is provided on the back of the FPC module 3. The above-mentioned grid copper plating treatment is beneficial to accelerating the release of static electricity to improve the antistatic ability of the display screen.
