Description

Technical Field

[0001] The present invention relates to the field of image communication technology, and in particular to a television screen image optimization method, device, equipment and storage medium. Background Art

[0002] ‌LED LCD TV‌ refers to an LCD TV that uses LED lamp beads as backlight sources. It has high brightness, high contrast and rich colors. LED LCD TV uses LED lamp beads as backlight sources and controls the degree of light transmittance through the rotation of liquid crystal molecules to achieve image display.

[0003] LED LCD TVs are mainly composed of a display screen, a casing and a circuit board. In LED LCD TVs, the circuit board powers the display screen, which in turn enables the LED lamp beads to emit light as a backlight source. The light emitted by the LED lamp beads passes through the liquid crystal layer, and the orientation of the liquid crystal molecules in the liquid crystal layer controls the degree of light transmission, and then generates a clear image through the polarizing plate. After long-term use, dust accumulates on the LED lamp beads and other optical components of LED LCD TVs. When the LED LCD TV is in use, the dust will reflect stray light, thereby enhancing the dark light, thereby reducing the contrast of the TV image. At the same time, dust accumulation will change the path of light, causing the light to be unable to focus on the same focus when it is concentrated, making the image displayed on the screen unclear.

[0004] To this end, the prior art proposes a method for dynamically adjusting the backlight, which uses histogram data to dynamically reduce the backlight, meet energy efficiency index requirements and optimize picture quality, but still does not solve the problem of unclear TV images caused by dust accumulation.

[0005] In view of this, we propose a method, device, equipment and storage medium for optimizing television screen images. Summary of the invention

[0006] The purpose of the present invention is to provide a method, device, equipment and storage medium for optimizing television screen images to solve the problems raised in the above-mentioned background technology.

Connect the LED lamp beads to form a backlight source; ‌LED lamp beads serve as backlight sources to provide light for TV displays, enabling them to display images and text normally‌; S2. Connect the backlight source to the control chip; The control chip integrates the functions of the processor, memory and peripheral interfaces. The control chip realizes image display and control operations by decoding data signals and controlling the power supply of the LCD panel. The control chip adjusts the light by controlling the on / off state of the LED light ring, thereby changing the light and dark areas of the backlight source; S3. Place polarizing plate, TFT, liquid crystal, color filter film and polarizing plate in order in front of the backlight source to form an LED liquid crystal display screen; The polarizing plate changes the propagation direction and intensity of light, making the light entering the LCD screen more orderly, thereby improving the brightness and clarity of the screen; TFT is a thin film field effect transistor that drives each liquid crystal pixel to achieve high speed, high brightness and high contrast display effects; The main function of liquid crystal is to control the transmission of light through electric fields, thereby displaying images; S4.

High contrast ratio is crucial to display quality, which can make images clearer, more vivid and colors more vivid. Brightness refers to the intensity of light emitted by the display. Higher brightness allows the display to be clearly visible in bright environments. When the display brightness is insufficient, the image may appear dim and details may become blurred under strong light. Color saturation is an important parameter of color performance, which represents the color range and vividness that the monitor can display.

[0009] Preferably, the control chip realizes the control of contrast, brightness and saturation through backlight source and liquid crystal cross compensation; When the control chip receives image data, it decomposes the grayscale of the picture into two parts: liquid crystal grayscale and backlight grayscale. It then realizes cross compensation through liquid crystal rotation and the illumination area of ​​the backlight source to control the contrast, brightness and saturation.

[0010] Preferably, the light control algorithm includes MiniLED technology, direct-type LED technology and universal partition technology; MiniLED technology: By shrinking the LED lamp beads to the millimeter level, more precise backlight control can be achieved; ‌Direct-down LED technology‌: By placing LED lights directly below the screen, the brightness is controlled through multiple partitions to provide better light control effects; ‌Vanxiang Zoning Technology‌: Through QD-MiniLED and Vanxiang halo control technology, a stronger light control effect is achieved, the halo problem of traditional MiniLED TVs is solved, and the contrast and detail performance of the picture are improved.

When the ion fan is working, the ion fan drives the opening and closing plate to rotate through the opening and closing component, thereby realizing cleaning of the LED liquid crystal display screen. During the rotation of the opening and closing plate, the softener is driven to be discharged, and the inside of the display is cleaned with the airflow blown out by the ion fan to avoid excessive accumulation of dust on the optical components inside the display, which affects the picture image effect of the TV. At the same time, the heat dissipation effect of the display can be enhanced during the rotation of the opening and closing plate to avoid high temperature of the display. There are two air supply components, which are symmetrically installed in the driving cavity. An air supply plate is installed on the air supply component. The opening and closing component drives the air supply plate to slide cyclically through the air supply component to adjust the gas distribution in the driving cavity. The air supply plate makes the airflow blown out by the ion fan evenly distributed in the driving cavity, thereby ensuring the uniformity of cleaning the internal dust. At the same time, when the gas flows inside the display, heat transfer can be realized, thereby ensuring the uniformity of the overall temperature inside the display.

[0012] Preferably, the opening and closing assembly includes a rotating wheel, a reciprocating plate, an active rod, a clamping plate, a liquid storage bag and a hose; the rotating wheel is installed on the ion blower, and when the ion blower rotates, it drives the rotating wheel to rotate synchronously, and the rotating wheel is rotatably installed in the driving cavity, and the rotating wheel is provided with driving gear teeth, and a reciprocating plate is provided on the outer side of the circumference of the rotating wheel; a strip groove is provided at the middle end of the reciprocating plate, and the middle end of the strip groove is stacked to form driving gear teeth that match the rotating wheel, and transmission gear teeth are provided at both ends of the strip groove obliquely and symmetrically; one end of the reciprocating plate An extrusion groove is provided, and an extrusion protrusion is provided at the other end of the reciprocating plate; the active rods are symmetrically arranged at both ends of the reciprocating plate, and the two active rods are provided with extrusion grooves that match the reciprocating plate.

[0013] Preferably, a scraper is slidably mounted on the opening and closing plate, a scraper block with an equilateral triangle structure is provided on the scraper, a roller is rotatably mounted on the scraper, and a pushing block cooperating with the roller is provided in the ventilation cavity. When the opening and closing plate opens the ventilation hole, the opening and closing plate is deflected, and the scraper slides vertically downward under the action of gravity. At this time, the roller of the scraper contacts the surface of the pushing block and pushes the scraper to tilt along the surface of the pushing block. The scraper fits the surface of the opening and closing plate to clean the dust on the felt cloth on the surface of the opening and closing plate. When the opening and closing plate closes the ventilation hole, the opening and closing plate resets and rotates, and the opening and closing plate cooperates with the pushing block to squeeze the scraper to slide along the surface of the opening and closing plate. The scraper evenly applies the softener to ensure that the softener is evenly distributed on the opening and closing plate. The equilateral triangle structure of the scraper block on the scraper ensures that the scraper exerts a uniform force on the opening and closing plate during the upward and downward movements, thereby ensuring the uniformity of cleaning and applying.

The rocker pulls the connecting shaft to slide horizontally, and the connecting shaft drives the shaft sleeve thereon to move synchronously, and the shaft sleeve drives the air supply plate to move synchronously, so as to transport the airflow blown out by the ion fan to ensure the cleaning effect. At the same time, the airflow is evenly distributed in the driving cavity. When the shaft sleeve slides horizontally, the driving rod on the shaft sleeve slides in the driving groove.

A driving groove 1222 is symmetrically provided on the inner wall of the driving cavity 1221. An ion blower 2 is provided in the driving cavity 1221. The ion blower 2 can blow out an airflow containing ions, thereby reducing the intensity of static electricity, thereby reducing the static electricity field generated by the display when the TV is started, thereby reducing the adsorption of dust by the static electricity field, and reducing the amount of dust adhering to the display screen. The liquid storage cavity 1223 is used to place a softener, and the softener is used to clean the display in conjunction with the ion blower 2. A liquid inlet is provided above the liquid storage cavity 1223 for replenishing the softener. An opening and closing component 3 is provided above the ion fan 2. When the ion fan 2 is working, the ion fan 2 drives the opening and closing plate 4 to rotate through the opening and closing component 3, thereby realizing the cleaning of the LED liquid crystal display screen 11. During the rotation of the opening and closing plate 4, the softener is driven to be discharged, and the inside of the display is cleaned with the airflow blown out by the ion fan 2 to avoid excessive accumulation of dust on the optical components inside the display, which affects the picture image effect of the TV. At the same time, during the rotation of the opening and closing plate 4, the heat dissipation effect of the display can be enhanced to avoid the high temperature of the display; there are two air supply components 5, which are symmetrically installed in the driving cavity 1221. An air supply plate 6 is installed on the air supply component 5. The opening and closing component 3 drives the air supply plate 6 to slide cyclically through the air supply component 5 to adjust the gas distribution in the driving cavity 1221. The air supply plate 6 makes the airflow blown out by the ion fan 2 evenly distributed in the driving cavity 1221, thereby ensuring the uniformity of cleaning the internal dust. At the same time, when the gas flows inside the display, heat transfer can be realized, thereby ensuring the uniformity of the overall temperature inside the display.

[0027] The rotating wheel 31 is installed on the ion blower 2. When the ion blower 2 rotates, the rotating wheel 31 is driven to rotate synchronously. The rotating wheel 31 is rotatably installed in the driving cavity 1221. The rotating wheel 31 is provided with driving gear teeth 311. A reciprocating plate 32 is provided on the outer side of the circumference of the rotating wheel 31. The reciprocating plate 32 is slidably connected to the inner wall of the driving cavity 1221 through a limiting sliding groove, thereby ensuring the movement stability of the reciprocating plate 32; a strip groove 321 is provided at the middle end of the reciprocating plate 32, and the middle end of the strip groove 321 is stacked to form a driving gear tooth 311 arranged to cooperate with the rotating wheel 31. The strip groove 321 is provided with a plurality of driving gear teeth 311 arranged to cooperate with the rotating wheel 31. Transmission gear teeth 322 are obliquely symmetrically provided at both ends of the groove 321; an extrusion groove 323 is provided at one end of the reciprocating plate 32, and an extrusion protrusion 324 is provided at the other end of the reciprocating plate 32; the active rods 33 are symmetrically arranged at both ends of the reciprocating plate 32, and the active rods 33 are slidably connected with the inner wall of the driving cavity 1221 through the limiting sliding groove, and the two active rods 33 are provided with extrusion grooves 323 that cooperate with the reciprocating plate 32. When the rotating wheel 31 rotates, the driving gear teeth 311 mesh with the reciprocating plate 32, thereby driving the reciprocating plate 32 to slide. The driving gear teeth 311 of the rotating wheel 31 are self- The rotating wheel 31 has a quarter of a circle, so that the rotating wheel 31 can only mesh with the driving gear teeth 311 on one side of the reciprocating plate 32 during the rotation process, and then the reciprocating motion of the reciprocating plate 32 is realized by alternately meshing with the driving gear teeth 311 on both sides of the reciprocating plate 32. At the same time, since the rotating wheel 31 has gear teeth only for a quarter of a circle, the reciprocating plate 32 has intermittent pauses, and the dynamic, static, and dynamic cyclic motion of the reciprocating plate 32 is realized. The reciprocating plate 32 pushes the two active rods 33 to slide vertically upward through the extrusion groove 323 and the extrusion protrusion 324, and the two active rods 33 are synchronously moved in the same direction. Movement, the active rod 33 is symmetrically mounted with card plates 34 on both sides; the opening and closing plate 4 is rotatably mounted on the card plate 34, when the active rod 33 slides in the vertical direction under the action of the reciprocating plate 32, the active rod 33 drives the card plate 34 to move synchronously, and the card plate 34 drives the opening and closing plate 4 to rotate; the opening and closing plate 4 is rotatably mounted in the ventilation hole 121, and a felt cloth is provided on the opening and closing plate 4, and the felt cloth is used to absorb the softener, and the felt cloth is nested or pasted, so as to realize the installation and separation with the opening and closing plate 4, thereby realizing the replacement of the felt cloth, and ensuring the cleaning efficiency of the dust; The liquid storage capsule 35 is fixedly installed above the active rod 33. The liquid storage capsule 35 is connected to the liquid storage cavity 1223 through a one-way valve. The one-way valve limits the flow direction of the softener so that the softener can only flow into the liquid storage capsule 35 along the liquid storage cavity 1223. A hose 36 is symmetrically installed on the liquid storage capsule 35; the hose 36 is located on one side of the opening and closing plate 4, and the hose 36 is provided with a liquid outlet corresponding to the opening and closing plate 4. The active rod 33 moves vertically upward. When the active rod 33 moves vertically upward, the opening and closing plate 4 is in a rotation state of vertically closing the ventilation hole 121, and the active rod 33 squeezes the liquid storage capsule 35. The liquid storage capsule 35 The softener in the hose 36 flows out and squeezes the softener in the hose 36. The softener in the hose 36 is sprayed out from the liquid outlet and falls on the felt cloth of the opening and closing plate 4 to absorb the dust blown out by the ion fan 2, so as to clean the inside of the display and prevent the dust from affecting the image effect of the TV screen. When the active rod 33 moves vertically downward, the active rod 33 no longer squeezes the liquid storage capsule 35. Since the softener in the liquid storage capsule 35 is reduced, the pressure in the liquid storage capsule 35 is reduced, and the liquid storage capsule 35 absorbs the softener from the liquid outlet cavity through the one-way valve to replenish itself. A scraper 41 is slidably installed on the opening and closing plate 4, and a scraper 41 is provided on the scraper 41. There is a scraper block 411 with an equilateral triangle structure, a roller 412 is rotatably mounted on the scraper 41, and a pushing block 1211 cooperating with the roller 412 is arranged in the ventilation cavity. When the opening and closing plate 4 opens the ventilation hole 121, the opening and closing plate 4 deflects, and the scraper 41 slides vertically downward under the action of gravity. At this time, the roller 412 of the scraper 41 contacts the surface of the pushing block 1211 and pushes the scraper 41 along the surface of the pushing block 1211 to tilt. The scraper 41 fits the surface of the opening and closing plate 4 to clean the dust on the felt cloth on the surface of the opening and closing plate 4. At this time, the opening and closing plate 4 gradually opens the ventilation hole 121 and the driving block 1212 is pressed against the surface of the opening and closing plate 4. The cavity 1221 gradually moves away, and at the same time, the ion fan 2 is still blowing out gas from the ventilation hole 121 to the outside, so dust will not fall into the driving cavity 1221 again. When the opening and closing plate 4 closes the ventilation hole, the opening and closing plate 4 resets and rotates, and the opening and closing plate 4 cooperates with the pushing block 1211 to squeeze the scraper 41 to slide along the surface of the opening and closing plate 4. The scraper 41 evenly applies the softener to ensure that the softener is evenly distributed on the opening and closing plate 4. The scraper block 411 on the scraper 41 has an equilateral triangle structure, which ensures that the scraper 41 applies a uniform force to the opening and closing plate 4 during the upward and downward movements, ensuring the uniformity of cleaning and applying. The ion fan 2 is started, and the ion fan 2 drives the rotating wheel 31 to rotate synchronously. The rotation drives the reciprocating plate 32 to reciprocate through the driving gear 311. When the reciprocating plate 32 pushes the active rod 33 to move vertically upward, the active rod 33 drives the card plate 34 to move synchronously.
