The structure of the TFT LCD display module serves a number of purposes, including the provision of a light source, the establishment of the position of the LCD screen and the circuit board, and the prevention of any direct contact between the edges of the circuit board and the LCD screen and any external objects. The foundation of the design is comprised of the structural components of the TFT LCD liquid crystal display module, which acts as the base for development. An introduction to the structural design of the TFT LCD liquid crystal display module will be provided in the following paragraphs. This presentation will be brief and to the point.
The key components that comprise the TFT LCD liquid crystal display module are the backlight, the display screen, the circuit substrate, and the front frame. Backlights are also included in this category. The fundamental purpose of structural design is to examine the external structure and assembly structure of these primary components, as well as to determine whether or not they are capable of achieving the needs that the client has set forth for product specifications. Examining these structures and establishing whether or not they are capable of satisfying these requirements is crucial. When it comes to LCD displays, the structural design process often consists of two stages: the first stage involves the examination of the fundamental specifications, and the second stage involves the evaluation of the appearance scheme.
It is necessary for us to verify the specification summary of the LCD screen product that has been developed. This includes the display area size, resolution, module appearance (front frame) size, backlight brightness, and other relevant details. When it comes to TFT glass, the metal wire design frequently places restrictions on the size of the display area, which can be measured from the display area to the appearance of CF glass. When evaluating the PCB and COF, it is necessary to determine the needed area of the PCB substrate by using information such as the circuit design, the number of components, and the layout of the functional modules included in the circuit. You can roughly determine the look of the COF by consulting the COF documentation. This determination should be based on the resolution and the specifications of the circuit system. Evaluation of the brightness of the backlight: The brightness that is necessary for the backlight may be calculated by taking into account the transmittance of the structural display screen as well as the brightness parameters of the LCD screen product that has been developed. To calculate the brightness of the backlight source, divide the brightness of the module by the transmittance of the display screen. This will give you the intensity of the backlight. It is determined whether to employ a high brightness, high thickness straight down backlight or a low brightness, thin side light backlight. This decision is made based on the brightness needs of the backlight as well as the look requirements of the module. In addition, it is essential to analyse the fundamental structure that is responsible for supporting and securing the display screen and the backlight source. This structure often includes the front frame, the rubber frame, the back panel, and other components that are typically supplied by the producer of the backlight.
It is necessary to integrate the evaluation results of the display screen, backlight, front frame, rubber frame, back panel, FCB substrate, and COF at this stage. Additionally, it is necessary to clarify the overall appearance of the LCD module and further evaluate whether the overall appearance plan meets the specification summary of the LCD screen product that has been developed. The examination of the display screen's look often necessitates that the centre of the display area of the display screen be consistent with the centre of the module, with a variance of no more than three millimetres being permitted. In order to properly evaluate the backlight source, it is necessary to ensure that the centre of the luminescent region and the centre of the display area of the backlight source are same. The evaluation of the appearance of the FCB substrate and COF primarily entails analysing the crimping positions and procedures of the PCB substrate and COF. To be more specific, it is to evaluate the configuration approach for the actual assembly of the substrate, such as determining whether the bend is in the shape of a U or an L. You will need to determine the length of the COF as well as its position based on the configuration of the PCB substrate. Determine, as a last step, if the substrate and COF can be completely incorporated into the shape of the module after the actual crimping has taken place.
For the purpose of enhancing the cost-effectiveness of LCD display products, the structural design of the TFT LCD liquid crystal display module should not only guarantee the dependability of the technology, materials, and assembly in the functional design, but it should also guarantee the safety, aesthetics, and environmental protection in the quality design.
