There were advantages and disadvantages to both the LCD projector and the LCD projector. It was not easy to determine which one was better. The following analysis was done from many aspects: ** 1. Principle of imaging ** - ** DLC projector **: Based on digital optical technology, it reflects light through the PDD chip. Among them, the PDD chip was a reflective surface composed of tens of thousands of micro-lenses, each of which represented a single pel. When working, light from the light source is directed to the surface of the MDD chip, and the lens changes the slope back and forth, causing the light to be reflected to the lens path to turn on or off the lens path. In order to define the color, a color wheel containing red, green, and blue filter was needed. The color wheel rotated on the light path between the light bulb and the MDD chip, and the micro lens reflected the light in real time according to the color requirements of each pel, thus producing an image projected on the screen. In high-end professional applications, the use of three separate MDD chips (three-chip DPS technology) could achieve purer and more accurate colors, but the cost and size were also greatly increased. - **LCD projector **: It is a liquid crystal display technology. It consists of three independent LCD glass panels (corresponding to the three video signal components of red, green, and blue). The 3LCD technology is more common. Each LCD panel contained many liquid crystals, which worked like shutters or shutters. They could be arranged to open, close or partially close to control the amount of light passing through. When red, green and blue passed through different LCD panels, the liquid crystals opened and closed based on the color requirements of the pixels', and the light was adjusted to produce a projected image. There were also models with an LCD panel that were suitable for entry-level home entertainment scenes, but the brightness was relatively low. ** 2. In terms of performance indicators ** - ** Brightness ** - ** DLC projector **: Compared with 1LCD projector, the brightness index of the DPS projector is a breakthrough. The optical machine efficiency is relatively high, and the light loss is relatively low. Therefore, it can output higher brightness under the same light source. This allowed the DLC projector to have a better projection effect in a brighter environment (such as a room that was not completely blocked during the day). - **LCD projector **: The light consumption of the projector with LCD technology is relatively serious. The effective light that can be projected on the screen is often less than 3% of the total light emitted by the light source. Therefore, the overall brightness is not high. When using it, it has a high requirement for the surrounding light. Generally, it can only have a better projection effect in a darker environment (such as closing the curtains at night or during the day). However, with the development of technology, the brightness of the single LCD projector was constantly increasing. - ** Comparisons and Image Quality ** - ** DLC projector **: High contrast and image quality, and the projected image is clear, especially when displaying black parts. It can show a good sense of layering, suitable for watching movies and other scenes that require high image quality. - **LCD projector **: The contrast is relatively low, and the projected image may produce halation. The black level of the image is not very good, and the overall image quality is slightly inferior in this aspect. - ** Color expression ** - ** DLC projector **: It has a wider color range and can display richer colors, especially red and green. - **LCD projector **: The color performance is average. - ** resolution ** - ** DLC projector **: Compared to 1LCD projector, the resolution of the DPS projector is a breakthrough. In addition, the use of three-chip DPS technology in high-end applications could achieve higher resolution and make the picture more exquisite. - **LCD projector **: The resolution of a model with a single LCD panel is relatively low, but the 3LCD technology can also meet the general usage requirements in terms of resolution. ** 3. Other aspects ** - ** Service Life ** - ** DLC projector **: Its lifespan is mainly determined by the PDD chip and the color wheel. It can be used for many years and is still stable and reliable. - **LCD projector **: The lifespan of the LCD panel is relatively long, but the lifespan varies according to the brand and technology. - ** Price * - ** DLC projector **: The price of a DPS projector is 3000 or 4000 yuan, which is relatively high. However, different brands, models, and specifications would have a large price difference. - **LCD projector **: Single LCD projector is generally not expensive. Most of them are between 1000 - 2000 yuan, and some are less than 1000 yuan. The cost-performance ratio is relatively high. ** 4. Market share ** - In the first half of 2024, the single LCD projector market share was 68.6%, an increase of 5% from the first half of last year. During the 11/11 promotion period in 2024, 1LCD technology accounted for 50.1% of sales, down 20.8 percentage points from the first three quarters of 2024. The sales share of the overall online market reached 47.0%, 19.4 percentage points higher than the first three quarters of 2024. When choosing a LCD projector or a LCD projector, you need to consider the specific needs, environment, budget, and other factors. If it is often used in a brighter environment, has high requirements for color and picture quality, and has a sufficient budget, you can give priority to a DLC projector; if the budget is limited and it is mainly used in a darker environment (such as bedroom viewing), an LCD projector is also a good choice.
