LCD TV panel prices, which peaked in summer 2021, fell through the second half of the year and are continuing to fall in the new year. The pace of price decreases is slowing, and we expect that pattern to continue through the first half of the year as prices approach cash cost for some panel makers.

In our updates in the summer of 2021, we referred to a series of events that suggested slowing demand and increasing supply, and no developments since have altered this outlook. The increasing panel prices led to an unprecedented increase in TV prices in the US and around the world, which hindered demand. Inventory is now more than sufficient across the LCD value chain from panel makers to retailers, which acts as a headwind for panel prices (or a tailwind for price declines!).

The last chart here shows our TV price index, set to 100 for prices in January 2014, and the Y/Y change of LCD TV panel prices. Our index increased from its all-time low of 42 in May 2020 to 87 in June 2021, but prices already declined to 45 in January. We now expect the index to decline to 41 by April, 50% lower than March 2021 and representing an all-time low for LCD TV panel prices. Although we don’t expect every screen size to hit all-time lows in Q1, 75” panels already hit an all-time low in January and we expect 65” to hit an all-time low by May.

After a full year of rising LCD TV panel prices, the natural effect of rising prices on both supply and demand has kicked in, and prices are starting to fall, based on our latest update and forecast of LCD TV prices. The demand surge, which resulted from the COVID-19 pandemic, has eased and industry supply has caught up to demand. Prices in August and September are falling faster than expected and we now forecast that year-end prices will be lower than they were in December 2020, but still substantially higher than their all-time lows.

LCD panel prices have risen for 4 months in a row because of your home gaming? Since this year, the whole LCD panel market has smoked. Whether after the outbreak of the epidemic, LCD panel market prices rose for four months, or the panel giants in Japan and South Korea successively sold production lines, or the Chinese mainland listed companies frequently integrated acquisition, investment, and plant construction, all make the industry full of interesting.

LCD panel prices are already a fact. Since May this year, LCD panel prices have risen for four months in a row, making the whole industry chain dynamic. Why are LCD panels going up in price in a volatile 2020? The key factor lies in the imbalance between supply and demand.

The price of LCDS for large-size TVs of 70 inches or more hasn’t budged much. In addition, LTPS screens and AMOLED screens used in high-end phones have seen little or no increase in price.

As for October, LCD panel price increases are expected to moderate. The data shows that in October 32 inches or 2 dollars; Gains of 39.5 to 43 inches will shrink to $3;55 inches will fall back below $10; The 65-inch gain will narrow to $5.

During the epidemic, people stayed at home and had no way to go out for entertainment. They relied on TV sets, PCS, and game consoles for entertainment. After the resumption of economic work and production, the market of traditional home appliances picked up rapidly, and LCD production capacity was quickly digested.

However, due to the shutdown of most factories lasting 1-2 months during the epidemic period, LCD panel production capacity was limited, leading to insufficient production capacity in the face of the market outbreak, which eventually led to the market shortage and price increase for 4 consecutive months.

In fact, the last round of price rise of LCD panels was from 2016 to 2017, and its overall market price has continued to fall since 2018. Even in 2019, individual types have fallen below the material cost, and the whole industry has experienced a general operating loss. As a result, LCD makers have been looking for ways to improve margins since last year.

A return to a reasonable price range is the most talked about topic among panel makers in 2019, according to one practitioner. Some manufacturers for the serious loss of the product made the decision to reduce production or even stop production; Some manufacturers planned to raise the price, but due to the epidemic in 2020, the downstream demand was temporarily suppressed and the price increase was postponed. After the outbreak was contained in April, LCD prices began to rise in mid-to-late May.

In fact, the market price of LCD panels continued to decline in 2018-2019 because of the accelerated rise of China’s LCD industry and the influx of a large number of local manufacturers, which doubled the global LCD panel production capacity within a few years, but there was no suitable application market to absorb it. The result of excess capacity is oversupply, ultimately making LCD panel prices remain depressed.

Against this background, combined with the impact of the epidemic in 2020, the operating burden of LCD companies in Japan and South Korea has been further aggravated, and it is difficult to make profits in the production of LCD panels, so they have to announce the withdrawal of LCD business.

business in June 2022. In August, Sharp bought JDI Baishan, a plant in Ishikawa prefecture that makes liquid crystal display panels for smartphones. In early September, Samsung Display sold a majority stake in its SUZHOU LCD production plant to Starlight Electronics Technology, a unit of TCL Technology Group. LGD has not only pulled out of some of its production capacity but has announced that it will close its local production line in 2020. According to DSCC, a consultancy, the share of LCD production capacity in South Korea alone will fall from 19% to 7% between 2020 and 2021.

It is worth mentioning that in industry analysis, in view of the fact that Korean companies are good at using “dig through old bonus – selling high price – the development of new technology” the cycle of development mode, another 2020 out of the LCD production capacity, the main reason may be: taking the advantage of China’s expanding aggressively LCD manufacturers, Korean companies will own LCD panel production line hot sell, eliminating capacity liquid to extract its final value, and turning to the more profitable advantage of a new generation of display technologies, such as thinner, color display better OLED, etc. Samsung, for example, has captured more than 80% of the OLED market with its first-mover advantage.

From the perspective of production capacity, the launch of LCD tracks by major manufacturers in Japan and South Korea must reduce some production capacity in the short term, which to some extent induces market price fluctuations. In the long run, some of the Japanese and Korean LCD production capacity has been bought by Chinese manufacturers, coupled with frequent investment in recent years, the overall capacity is sure to recover as before, or even more than before. But now it will take time to expand the production layout, which more or less will cause supply imbalance, the industry needs to be cautious.

The LCD panel industry started in the United States and then gradually moved to Japan, South Korea, China, and Taiwan. At present, the proportion of production capacity in The Chinese mainland has reached 52% in 2020, and there are leading LCD panel products in China represented by BOE, Huxing Optoelectronics. Meanwhile, the production capacity layout of BOE, Huike, Huxing Optoelectronics, and other manufacturers has been basically completed, making industrial integration a necessity.

On the one hand, South Korean enterprises out of the LCD track, the domestic factory horse enclosure, plant expansion action. While LCDs may not sell as well as “upstart” flexible screens, respondents believe they are still strong enough in the traditional home appliance market to warrant continued investment. Zhao Bin, general manager of TCL Huaxing Development Center, has said publicly that the next-generation display technology will be mature in four to five years, but the commercialization of products may not take place until a decade later. “LCD will still be the mainstream in this decade,” he said.

On the other hand, there is no risk of neck jam in China’s LCD panel industry, which is generally controllable. In mainland China, there will be 21 production lines capable of producing 32-inch or larger LCD panels by 2021, accounting for about two-thirds of the global total. In terms of the proportion of production capacity, the Chinese mainland accounted for 42% of the global LCD panel in 2019, 51% this year, and will continue to climb to 63% next year.

Of course, building factories and expanding production cannot be accomplished overnight. In the process of production capacity recovery, it is predicted that there will be several price fluctuations, and the cost may be passed on to the downstream LCD panel manufacturers or consumers when the price rises greatly, which requires continuous attention.

A lot of consumers wonder how manufacturers determine the LCD display panel prices. After all, display solutions such as TFT LCDs and HMI touch screens do not always come cheap. And sometimes, a few products that can indeed be purchased for lower prices may come with several quality issues.

Hence, we’ve rounded up a list of factors that influence how to display modules such as TFTs, LCD, and touch screens are priced. You can also use these factors to evaluate to whom you should place your next orders for your display solutions.

LCD fluids are used in altering the light orientation passing through glass substrates. Hence, this causes the panel’s active pixels to darken. Different kinds of LCD panel fluids provide unique characteristics and change a panel’s viewing angle, temperature range, and display clarity.

Another characteristic of this fluid is that it works well even in colder temperatures. It’s because TN fluid has the quickest response time among the other LCD fluid types.

TN fluid is considered the cheapest LCD fluid type. However, this doesn’t mean that TN isn’t widely used. The display technology is greatly utilized in digital clocks, pagers, and gas pumps.

LCD modules with STN fluid enjoy a wider display angle, greater multiplexing, higher image contrast, and sharper response than devices using TN fluids. However, modules with STN fluids may have slower response times when used in lower temperatures due to the fluid freezing inside the device.

STN fluid falls under the moderately cheap LCD module price. Furthermore, STN fluid is widely utilized in several monochrome LCD devices such as POS machines, inexpensive feature phones, and informational screens of some devices.

The CSTN fluid technology takes away the monochrome finish of the typical STN fluid devices. Red, green, and blue filters are added to the fluid module to allow a colored display. New versions of CSTN often feature a viewing angle of 140 degrees and 100ms response times.

CSTN is a bit pricier than TN and STN fluids. But it’s a good choice if you need to display color images on your LCD device. In fact, a lot of color feature phones use CSTN as an alternative to the TFT displays, saving almost half the manufacturing costs.

In terms of cost, the LCD display module price of a unit with FSTN is higher compared to TN and STN. But this is concerning the better visual quality that FSTN offers.

To cap off this part, the fluids used in a screen is a big factor in determining the overall LCD screen display panel price. As you can see, the four fluid types often used in LCD screens rise in costs with respect to the visual quality produced by each technology.

The temperature range in which LCD screen displays may work varies intensely. Some displays continue to work at optimal performance even when used in cold or hot outdoor temperatures. Lower-quality LCD panels may start having glitches at the slightest change of temperature and humidity. Hence, the temperature range may have a huge impact on the LCD display panel price as well.

Now, most LCD screen panels don’t experience such temperature extremes. In fact, a typical LCD TV can operate properly between approximately o°C and 32°C (32° – 90° F). Meanwhile, other screen modules (usually the industrial-grade ones) have unique capabilities to work in even more extreme ends of the temperature scale.

If you want to look for the most cost-effective type of LCD panel for your device, then you must consider the following standard LCD unit temperature types:

Normal temperature units work well in environments that have indoor temperatures at approximately 20-35°C (68-95°F). Some LCD modules may work well above up to 50°C (122°F). Such LCD modules can be used in daily settings by the typical consumer public.

LCD units under this type are made to withstand lower and higher temperature ranges. Extreme operating temperatures may range anywhere from -30°C to 85°C (-22-185°F). Most LCD modules with wide/extreme temperature capabilities are used in extremely cold areas such as Artic places and ski resorts, as well as humid and moisture-rich hot outdoor areas.

Generally, the LCD module price goes up if the entire display unit can withstand higher temperature ranges. Those who can operate under normal temperature ranges only are usually cheaper.

Hence, you must consider the places where you’ll be installing your LCD display devices. You can’t just use cheaper LCD modules for an industrial-grade display machine. Treat your LCD panel as an investment and select a panel that will yield better screen performance that’ll last several years for you and your business.

It’s an unspoken rule, but monochrome modules are generally cheaper than color-capable ones. However, color-capable display modules may also have cost variations depending on their display capabilities.

Color LCDs have three subpixels that hold red, blue, and green color filters. Each subpixel can have as much as 256 color shades, depending on the variation and control of the voltage applied to it.

Now, when you combine 256 shades of both red, blue, and green subpixels, color LCDs can display a color palette of up to 16.8 million colors. And all these are made possible by millions of transistors etched onto the glass modules.

Display size also plays a large role in an LCD device’s color capability. Smaller screens need fewer pixels and transistors since they have smaller display sizes. These screens are also less costly to make. Now, larger screens with high color resolution and huge display sizes require more transistors and pixels, justifying the higher prices of such monitors.

A touch screen display module is more costly than a non-touch monitor module. Touch capability is integrated into Human Machine Interface (HMI) modules and is generally used in kiosks, bank ATMs, hospital equipment, and similar devices in other industries.

This type of touch screen technology is made up of a top polythene layer and a glass-bottom layer separated by microdots or an air gap. This module is then attached to a touch screen controller.

Capacitive touch screens are the most common in the display industry today. This technology uses transparent conductors, insulators, and glass to create the panel. An electrostatic field change in the screen’s module happens when a human finger touches the screen surface. This ultimately creates signals that are sent to the touch screen controller for processing.

Infrared grid technology uses photodetector pairs and X-Y infrared LED components to allow sensors to pick up the touch and its exact location. Infrared grids have been used in several touch screen modules before the capacitive touch screen technology took over.

We’ve explained the following factors at length for both public consumers and business clients to understand the variations in TFT, LCD, and HMI touch screen prices.

Cheap doesn’t necessarily mean low-quality. Also, expensive options aren’t always a wise choice, either. You can maximize your buying or manufacturing options if you know how to compare LCD modules and panels depending on the specifications you truly need for your display machines and devices.

It may seem odd in the face of stalled economies and stalled AV projects, but the costs of LCD display products are on the rise, according to a report from Digital Supply Chain Consulting, or DSCC.

Demand for LCD products remains strong , says DSCC, at the same time as shortages are deepening for glass substrates and driver integrated circuits. Announcements by the Korean panel makers that they will maintain production of LCDs and delay their planned shutdown of LCD lines has not prevented prices from continuing to rise.

Panel prices increased more than 20% for selected TV sizes in Q3 2020 compared to Q2, and by 27% in Q4 2020 compared to Q3, we now expect that average LCD TV panel prices in Q1 2021 will increase by another 12%.

All that said, LCD panels are way less costly, way lighter and slimmer, and generally look way better than the ones being used 10 years ago, so prices is a relative problem.

Looking to take your project to the next level in terms of functionality and appearance? A custom LCD display might be the thing that gets you there, at least compared to the dot-matrix or seven-segment displays that anyone and their uncle can buy from the usual sources for pennies. But how does one create such a thing, and what are the costs involved? As is so often the case these days, it’s simpler and cheaper than you think, and [Dave Jones] has a great primer on designing and specifying custom LCDs.

The video below is part of an ongoing series; a previous video covered the design process, turning the design into a spec, and choosing a manufacturer; another discussed the manufacturer’s design document approval and developing a test plan for the module. This one shows the testing plan in action on the insanely cheap modules – [Dave] was able to have a small run of five modules made up for only $138, which included $33 shipping. The display is for a custom power supply and has over 200 segments, including four numeric sections, a clock display, a bar graph, and custom icons for volts, amps, millijoules, and watt-hours. It’s a big piece of glass and the quality is remarkable for the price. It’s not perfect – [Dave] noted a group of segments on the same common lines that were a bit dimmer than the rest, but was able to work around it by tweaking the supply voltage a bit.

We’re amazed at how low the barrier to entry into custom electronics has become, and even if you don’t need a custom LCD, at these prices it’s tempting to order one just because you can. Of course, you can also build your own LCD display completely from scratch too.

여기에서, 먼저 판체(7)는 가격표시판(1)의 바탕판으로서, 도 4에 도시된 바와 같이 일반적인 가격표시판과 마찬가지로 맨 윗부분에 "차림표"라는 제목이 표시되어 있다. 그 아래로 좌측에는 도장, 접착, 조립등 다양한 인자방법에 의해 다양한 종류의 음식물 이름 등 내용부분(9)이 선택적으로 표시된다. 그리고 각각의 내용부분(9) 즉, 음식물 이름 우측으로 해당 음식물의 가격을 나타내는 표시모듈(3)이 일대일 대응되도록 차례로 장착된다. 이때, 특히 판체(7)에 "오늘의 메뉴"를 표시할 경우에는 기재, 부착 또는 삽입 등 기존의 방식에 의해 음식물 이름을 수시로 변경할 수 있는 내용변경부분(10)을 둘 수 있는데, 도 4의 실시예에서는 밑줄을 그어 그 위에 수성매직 등 필기도구를 이용해 음식물 이름을 기재하도록 되어 있다.Here, the plate body 7 is a base plate of the price display plate 1, and as shown in FIG. 4, the title "dress table" is displayed at the top as in the general price display plate. Below the left side, content parts 9 such as names of various kinds of foods are selectively displayed by various printing methods such as painting, gluing, and assembling. In addition, each content portion 9, that is, the display module 3 indicating the price of the food to the right of the food name, is mounted in order to correspond one-to-one. At this time, in particular, when displaying the "menu of the day" on the plate (7), there can be a content change part 10 that can change the food name at any time by the existing method such as description, attachment or insertion, Figure 4 In the embodiment, underlined and written on the food name using a writing instrument such as aqueous magic.

판체(7)는 또한, 도시된 것처럼 우하단 등 적절한 지점에 입력모듈(5)이 장착되어 있으며, 마찬가지로 온오프 스위치(15)이 측면 또는 전면 일측에, 제어회로기판(미도시)이 내부에 각각 장착되어 있다. 특히, 판체(7)의 전면 일측에는 IR센서(29)가 장착되는 바, 이 센서(29)로부터 리모컨 신호를 수신함으로써 회로기판에 장착된 마이크로프로세서(17)를 통해 표시모듈(3)을 원격 조정할 수 있게 된다.The plate 7 is also equipped with the input module 5 at a suitable point such as the lower right as shown, the likewise the on-off switch 15 on one side or the front side, the control circuit board (not shown) inside Each is attached. In particular, an IR sensor 29 is mounted on one side of the front surface of the plate 7 so that the display module 3 can be remotely controlled through the microprocessor 17 mounted on the circuit board by receiving a remote control signal from the sensor 29. You can adjust it.

음식물 등 표시 내용부분(9)의 가격을 표시하는 표시모듈(3)은 도 4에 도시된 바와 같이, 복수의 숫자표시부(13)를 일렬로 이어붙여 가격을 표시하게 된다. 따라서 표시모듈(3)은 가격 표시에 충분한 갯수 예컨대, 도 4와 같이 5개의 숫자표시부(13)를 이어붙임으로써 음식물 가격을 표현하기에 충분한 5자리수를 만들 수 있게 된다.As shown in FIG. 4, the display module 3 displaying the price of the display content portion 9 such as food or the like displays the price by connecting the plurality of numeric display units 13 in a row. Therefore, the display module 3 can make a sufficient number for displaying the price, for example, by connecting the five number display unit 13 as shown in FIG.

각 표시모듈(3)의 숫자를 입력하고, 변경하는 등 입력수단의 역할을 하는 입력모듈(5)은 입력수단으로서 기계적 스위치 등 다양한 장치를 채용할 수 있으나, 본 실시예에서는 도 6에 도시된 것처럼 터치스크린 모듈을 적용한다. 여기에서, 터치스크린 모듈(5)은 통상의 터치스크린 모듈과 마찬가지로 터치스크린 패널(31), 터치스크린 검지부(33), 터치스크린 컨트롤러(35) 그리고 터치스크린 패널 구동부(37)로 구성되는 바, 터치스크린 패널(31)에 0부터 9까지의 아라비아 숫자가 기재된 숫자버튼(39)이 표시되어 있는 점을 제외하면, 일반적으로 널리 알려진 구성이므로 상세한 설명은 생략한다.The input module 5 serving as an input means such as inputting and changing the number of each display module 3 may employ various devices such as a mechanical switch as the input means. Apply the touch screen module as if. Here, the touch screen module 5 is composed of a touch screen panel 31, a touch screen detector 33, a touch screen controller 35, and a touch screen panel driver 37, like a normal touch screen module. Except for the fact that the numeric buttons 39 in which Arabic numerals from 0 to 9 are displayed on the touch screen panel 31 are generally well-known configurations, detailed description thereof will be omitted.

다만, 본 고안의 터치스크린 모듈(5)은 우측하단 즉, 9자 밑에 C자가 표시된 반전버튼(41)이 위치하는 바, 이 반전버튼(41)은 컴퓨터 자판기의 넘록키(Num-Lock Key)와 반대로 오프 시에는 나머지 버튼들이 정상 동작되나, 온 시에는 각각의 숫자버튼(39)이 표시모듈(3)의 행번호를 나타낸다. 즉, 1번 버튼을 누르면 맨 윗줄의 표시모듈(3)이 선택되는 방식으로 숫자 입력이 필요한 표시모듈(3)이 선택된다. 그리고 밑줄버튼(43)은 도 5에 도시된 밑줄 패널(25)을 비추는 LED(27)를 온오프시켜 강조하고 싶은 음식물 가격 밑에 줄을 친 효과를 준다.However, the touch screen module 5 of the present invention has a reverse button 41 marked with a letter C at the bottom right, that is, 9 characters, and the reverse button 41 is a num-lock key of a computer vending machine. On the contrary, the remaining buttons operate normally when turned off, but when turned on, each number button 39 indicates a row number of the display module 3. That is, when the first button is pressed, the display module 3 requiring the number input is selected in such a manner that the display module 3 of the top row is selected. In addition, the underline button 43 turns on and off the LED 27 illuminating the underline panel 25 shown in FIG.

한편, 표시모듈(3)에 가격을 입력하거나 변경하는 입력모듈로서, 위와 같이 별도의 터치스크린 모듈(5)을 사용하는 대신에 5에 도시된 것처럼 표시모듈(3)과 일체로 표시모듈(3) 상단에 설치되어 사용자의 터치 회수를 카운팅하여 터치회수의 총합을 숫자로 표시하는 카운팅 기능만을 갖는 단순한 형태의 터치스크린 모듈(5")을 채용할 수도 있다.On the other hand, as an input module for inputting or changing the price on the display module 3, instead of using a separate touch screen module 5 as described above, as shown in 5, the display module 3 integrally with the display module 3 It is also possible to employ a simple form of the touch screen module 5 "having only a counting function installed at the top and counting the number of touches of the user to display the total number of touches as a number.

본 고안의 가격표시판(1)을 사용하기 위해서는 먼저 전원 스위치(15)를 온시켜 직류 또는 교류 전원을 공급한다. 그리고나서, 다양한 인자수단에 의해 기작성된 음식물 메뉴이름 옆에 표시모듈(3)을 통해 해당하는 가격을 표시하게 되는데, 일단 도 4에 도시된 반전버튼(41)을 눌러 터치 스크린(5)의 모드를 이동모드를 전환한다. 그 다음, 음식물 가격을 입력 또는 변경하고자 하는 표시모듈(3)의 행번호에 해당하는 숫자를 누르면 해당 행의 표시모듈(3)로 커서가 이동한다. 이와 같이, 원하는 행의 표시모듈(3)로 커서가 이동한 뒤, 재차 반전버튼(41)을 눌러 이동모드를 해제하고, 해당 음식물의 가격을 입력한다.In order to use the price display board 1 of the present invention, the power switch 15 is first turned on to supply DC or AC power. Then, the corresponding price is displayed through the display module 3 next to the food menu name written by various printing means, and once the reverse button 41 shown in FIG. 4 is pressed, the mode of the touch screen 5 is displayed. To switch to the move mode. Next, when the number corresponding to the row number of the display module 3 to input or change the food price is pressed, the cursor moves to the display module 3 of the row. In this way, after the cursor is moved to the display module 3 of the desired row, the inversion button 41 is pressed again to cancel the moving mode and input the price of the food.

이렇게 첫 번째 입력이 끝나면 재차 반전버튼(41)을 누른 다음 두 번째로 입력하고자 하는 표시모듈(3) 예컨대, "오늘의 메뉴"의 행수 7번을 누르고 나서 음식물 가격을 입력한다. 이때, 밑줄 버튼을 누르면 해당 표시모듈(3)의 밑줄 패널(25)이 점등되어 가격표시 전체에 밑줄을 친 효과를 줄 수 있다. 이렇게 해서 원하는 모든 표시모듈(3)에 가격을 입력 또는 수정한 뒤에는 최종적으로 반전버튼(41)을 누르고 0자 버튼을 눌러 가격표시 작업을 종료하게 된다.When the first input is completed, the invert button 41 is pressed again, and then the display module 3 to be input for the second time is pressed, for example, the number of rows 7 of the menu of the day is input, and then the food price is input.
