tft lcd size factory

In a typical LCD factory, a large number of product types are produced concurrently, 24 hours a day and 365 days a year, and there exist various constraints and re-entrant flows in the manufacturing processes. As a result, efficient planning and scheduling of LCD production is a big challenge. Presented in this paper is a simulation-based DPS (daily planning & scheduling) system that was developed by the authors and is being used in a modern LCD Fab in Korea. Also presented in the paper are a business architecture of LCD production management, internal structure of the DPS system, and Fab scheduling logic. The DPS system was installed at a large-size LCD Fab in 2006, and the system has been successfully used for two years leading to a considerable increase in on-time production of LCD panels and a sharp decrease in turn-around time.

TFT displays are now used in a wide range of products, including TVs, computers, appliances, medical equipment, instruments, mobile, and other gadgets. The utilization of LCDs in all market segments was significantly enhanced by incorporating thin film transistors into LCD architecture.

The liquid crystal display (LCD) uses TFT (thin-film transistor) technology and contains a transistor for each pixel (that is, for each of the tiny elements that control the illumination of your display). Since each pixel has a transistor, the current that initiates pixel lighting may be reduced and turned on and off more quickly. The active matrix display technology is another name for TFT (and contrasts with the "passive matrix," which does not have a transistor at each pixel).

The materials required to make a TFT display include ITO glass, liquid crystal, polarizer, sealing glue, and intermediate powder. These components themselves are simple enough, but the manufacturing process can often involve heavy investment in tooling, sourcing, and research. Each step of the process requires a unique line and space in the factory, along with dedicated design, engineering, and manufacturing staffing.

A custom sized TFT display will likely need to be designed such that each component fits into an appropriately sized housing that the project will require; this will often require experimentation and creative resources.

Finally, economies of scale play a massive role in cost and pricing. Economies of scale relate to the cost-benefit a company has when it raises its output level for a specific screen size—the benefit results from the inverse connection between the amount produced and the fixed cost per unit. The fixed cost per unit decreases as production volume increases.

Therefore, it may not make sense for a small project scope if you need a small number of TFTs with custom sizes. While the overall cost may be lower due to unit price reductions as the number of displays purchased leads to a decreased cost per unit, this price reduction will not be feasible with a smaller purchase size of custom-size displays. Additionally, when considering the tooling cost, this is not able to be spread over a smaller number of custom displays purchased, leading to limited cost savings on small purchase orders. Custom can be cheaper if your project falls within mid-range volumes, but this is not the case for small projects.

Consequently, due to design, sourcing of materials, manufacturing considerations, and cost and time of quality assessment, it can be impractical to order a custom TFT configuration for smaller projects. Fortunately, FocusLCDs offers a wide variety of mass-produced screen sizes that allows you to benefit from economies of scale and may even be a perfect fit for your specific project.

RELEC’s standard TFT Displays are available in a wide range of sizes, from small 1.77” up to 31.5”. These cover all industry-standard resolutions, sizes, and interfaces. Standard units are available with brightness levels exceeding 1500 cd/m² and can be supplied with or without resistive or PCAP touch panels.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) dominates the world flat panel display market now. Thanks for its low cost, sharp colors, acceptable view angles, low power consumption, manufacturing friendly design, slim physical structure etc., it has driven CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) out of market, squeezed LED (Light Emitting Diode) displays only to large size display area. TFT LCD displays find wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, handheld devices, video game systems, projectors, consumer electronic products, advertisement etc. For more information about TFT displays, please visit our knowledge base.

There a lot of considerations for how to choose a most suitable TFT LCD display module for your application. Please find the check list below to see if you can find a right fit.

It is the start point for every project. There aretwo dimensions to consider: outside dimension (width, height, thickness) and AA (active area or pixel area). Orient Display’s standard product line ranges from 1.0” to 32”. Our OLED size can go down to 0.66” which fit for wearable devices.

Resolution will decide the clearance. Nobody likes to see a display showing pixel clearly. That is the reason for better resolution, going from QVGA, VGA to HD, FHD, 4K, 8K. But higher resolution means higher cost, power consumption, memory size, data transfer speed etc. Orient Display offers low resolution of 128×128 to HD, FHD, we are working on providing 4K for our customers. For full list of resolution available, please see Introduction: LCD Resolution

TFT screen brightness selection is very important. You don’t want to be frustrated by LCD image washout under bright light or you drain the battery too fast by selecting a super brightness LCD but will be used indoor only. There are general guidance listed in the table below.

Orient Display offers standard brightness, medium brightness , high brightness, and high end sunlight readable IPS TFT LCD display products for our customers to choose from.

If the budget is tight, TN type TFT LCD can be chosen but there is viewing angle selection of either 6 o’clock or 12 o’clock. Gray scale inversion needs to be taken of carefully. If a high-end product is designed, you can pay premium to select IPS TFT LCD which doesn’t have the viewing angle issue.

It is similar to viewing angle selection, TN type TFT LCD has lower contrast but lower cost, while IPS TFT LCD has much high contrast but normally with higher cost. Orient Display provides both selections.

Normal TFT LCD displays provide wide enoughtemperature range for most of the applications. -20 to 70oC. But there are some (always) outdoor applications like -30 to 80oC or even wider, special liquid crystal fluid has to be used. Heater is needed for operating temperature requirement of -40oC. Normally, storage temperature is not an issue, many of Orient Display standard TFT display can handle -40 to 85oC, if you have any questions, feel free to contact our engineers for details.

Power consideration can be critical in some hand-held devices. For a TFT LCD display module, backlight normally consumes more power than other part of the display. Dimming or totally shutdown backlight technology has to be used when not in use. For some extreme power sensitive application, sleep mode or even using memory on controller consideration has to be in design. Feel free to contact our engineers for details.

High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.

If you can’t find a very suitable TFT LCD Display in our product line, don’t be discouraged. The products listed on our website is only small part of standard products. We have thousands of standard products in our database, feel free to contact our engineers for details.

If you like to have a special display, Orient Display is always flexible to do partial custom solution. For example, to modify the FPC to different length or shape, or use as fewer pinouts as possible, or design an ultra-bright LCD display, or a cover lens with your company logo on it, or design an extreme low power or low cost TFT display etc. our engineers will help you to achieve the goals. The NER cost can start from hundreds of dollars to Thousands. In rare case, it can be tens of thousands of dollars.

A fully custom TFT LCD panel can have very high NRE cost. Depending on the size of the display, quantity and which generation production line to be used. The tooling cost can start from $100,000 to over $1M.
