The principles of the lcd drive plate and of the lcd drive plate are often referred to as the a/d (simulation/digital) panel, which in a sense reflects the main function achieved by the drive. For the lcd screen to display the image digitized video signal, the lcd drive is the functional module that completes the conversion from the analogue to the digital signal (or from one digital signal to another) and at the same time drives the image to the lcd under the control of the image control unit. The driver of the lcd monitor is shown in figure 1, figure 2. When applied, the corresponding voltage transformer component and the rear load are checked if an anomaly of a group of vgh, vgl, vdd, vda voltage is detected. Figure 1. The lcd displays used in the drive plate 2 part of the lcd displays are based on a general drive plate, as shown in figure 3. The lcd drives typically contain components such as the master chip, the mpu microcontroller, the rom repository, the power module, the power interface, the vga video signal input interface, the osd keyboard interface, the high pressure plate interface, and the lvds/ttl drive signal interface. The rationale for the lcd drive is illustrated in figure 4. Video signals sent from the computer host display card are sent to the main control chip of the drive via the vga video signal input interface on the driveboard, which controls the image of the lcd screen based on the information on the lcd in the mpu microcontroler. At the same time, the mmu microcontroller achieves power control, functional operation, etc. For the whole machine. Thus, the lcd drive is also known as the lcd monitor's main board. Five generations of tft-led production lines were officially opened, with investments of $46 billion in the project plus a total investment of more than $70 billion in the accompanying project。
Guangzhou genesis mechanical equipment co. Ltd. Is a compact screen manufacturer that produces various types of lcd maintenance equipment, large lcd screens, lcd screens, pulse screens, thermo-screens, fob screens, fog screens, fpc presses, diaphragms, photofilm patches, lasers, glue machines, etc. Products from all over the world: guangdong, fujian, chongqing, sichuan, hunan, hubei, guangxi, jiangsu, shandong, ningxia, xinjiang, guizhou, india, africa, bangladesh, turkey, pakistan... Calling and asking is preferential! On 20 december 2017, the east of kyoto announced an investment of $45. 8 billion in the construction of the tenth. What happens when a wire appears in the middle of a television set, in the case of a regular television set, is a scanned circuit failure: one, an output block is active or damaged. 2. Electrical resistance to the output of the field is damaged or welded. The output capacitor damage. 4 poor contact with the siding plug. 5. Partial electrical damage caused by the shock caused the disruption. This is a frequent failure of the general television and can be repaired by repairing home electricity if it is unable to do so. In the case of lcd wires, there are usually the following reasons: (1) the main panel circuit or the line-line problem of connecting the lcd screen, which is relatively simple and can be resolved by replacing the main panel or line. The lcd screen problem can only be replaced. 3. The line inside the glass on the screen corrupted. There's a problem with the chip. 5. A component is burned。

Calling and asking is preferential! A special reminder is that the increase in resistance from r554 (150k) in the tri-ocean power supply has resulted in +b overburning of pipe and even crt, and it is recommended that it be protected by a r2m next to +b。
What are the aspects of television maintenance? Both medium frequency amplifiers and video amplifiers are currently concentrated in an integrated circuit, such as the commonly used la7680, la7685, etc. When sent to it by the medium-frequency television xin, which is exported from the high-frequency head, it sends the image signal directly to the cathode; this maintenance summarised that auo-p301-30/16 electrical circuits, which work independently on the booster pump component, the negative pump component, the pressure control component of the negative pump, and the pressure control component of the booster pump, are working independently. Give the acoustic signal to the acoustic circuit. Besides, this integrated circuit needs an output field, a resonance
