With the continuous development of LED light sources, micro projectors have gradually entered our lives. Especially with the continuous progress of LED light source technology, the traditional bulb light source projection has faded out of the projection market. The biggest advantage of using LED light source is its small size and long life, but it also has its fatal disadvantage of low brightness. However, it is believed that with the continuous maturity of LED light source technology, 3000 lumens is no longer possible, just how to reduce costs. Shenzhen Kuletv Technology Co., Ltd. is a young enterprise focusing on the research, development and promotion of digital image products. Since its launch, the Q6 series micro projector has been favored by everyone, especially the latest Q6 flagship version (New), whose brightness has increased by 30% compared with the ordinary version.

1、 Product packaging and details

The packaging of the Q6 flagship (New) mini projector is in order. The logo of the product is on the upper left corner, and the "Mobile Projection Companion" on the lower right corner shows that the main feature of the Q6 flagship (New) is connected to the mobile phone. On the back of the package are the technical specifications and relevant information of the product. Open the upper cover of the package, you can see the neat inner package. Each accessory adopts an independent inner package, which is marked on the box in the form of icons for easy access and use.

In addition to the projector host, the Q6 flagship (New) also has power adapter, USB charging cable, HDMI cable, tripod, velvet bag, San Bao certificate, operation guide and certificate of conformity. In particular, this velvet bag is convenient to carry, which is very considerate.

The surface of the body of Kuletv Q6 flagship (New) adopts H9 scratch resistant explosion-proof glass mirror. There are seven touch keys on the panel, which control the functions of up, down, left, right, menu, confirmation and return respectively. However, these keys sometimes show a lag phenomenon in the actual experience.

The frame of Kule Q6 flagship version (New) uses aluminum magnesium alloy, which is meticulously made by CNC, with streamer side and precise hole position, and Tuhao gold to make the whole body line appear streamer.

The external interfaces of the Q6 flagship (New) are also very rich. The front is the lens and heat sink of the projector. On the left side is the manual focusing adjustment wheel, and on the right side are various external interfaces and power switches. The back is the headphone jack, which is suitable for the headphone experience when going out.

The overall dimension of Q6 flagship (New) is 145 * 78 * 15.8mm and weighs 230g. Similar in size to mobile phones, it is very convenient to carry when you go out. The most important thing is that the official data contains 5000MAH large capacity batteries (the truth is behind), and the actual use time reaches more than 2 hours.

2、 Actual use

This is the projection effect of Q6 flagship (New) under the shade of the park in the daytime, and the brightness is completely acceptable. Due to the reason of the site, the projection size is not too large during the test.

If you come out of the forest, the projection effect will become significantly worse, and you can barely see the projection content on the closer projection objects. The brightness of Q6 flagship version (New) is 75 ANSI lumens, which is very good to achieve this effect.

In general, the use experience of Q6 flagship (New) mini projection is very good, especially it can be connected to the mobile phone wirelessly, and it also supports Apple's AIRPLAY image function. When you go out, you can use the projector to connect to the mobile phone, and then you can directly project the mobile phone content. The Q6 flagship (New) mini projector also supports the use of TF cards, U disks and other devices. Another thing worth mentioning is that when the phone is out of power, you can use the Q6 flagship (New) mini projector as a temporary mobile power supply. However, there are also some disadvantages, such as the use of touch keys lags behind. Although WeChat connection can be used, there is no wireless when going out Cannot be used. At the same time, the support of Q6 flagship (New) micro projection is located at the heat sink. If a standard tripod is used, the head will cover the heat sink. It is recommended to move backward, which can also solve the problem of unstable center of gravity with a small tripod.

3、 Disassembly

The focus of this evaluation is mainly on the disassembly of the machine, so, for the Q6 flagship (New) micro projection In terms of content, we are not evaluating here. Let's begin to disassemble. There are 7 fixing screws below the Q6 flagship (New) micro projection. Remove these screws to separate the panel from the body.

When removing the panel, pay attention to the internal touch panel cable arrangement. Use a camera to remove it from the mainboard first. The WIFI antenna cable is relatively long, so it can not be processed.

After removing the panel, we can see the internal structure of Q6 flagship (New) micro projection. The touch panel on the panel is composed of a control chip, LED lights and peripheral components. Main board, optical machine and cooling fan can be seen in the body

On the motherboard, the largest chip T113AI is a video control chip developed by Macrocore Technology, which will be described in detail later.

Remove several screws on the motherboard to pick up the motherboard. Pay attention to the cable arrangement of the motherboard and other parts. After carefully removing, the motherboard can be removed.

After the mainboard is removed, you can see the built-in battery. From the battery label, you can see that the battery is a 364898 lithium battery of SEC company, with a battery voltage of 7.4 V and 2500 mAh. In the parameters of Q6 flagship (New) micro projection, it is clear that the battery capacity is 5000mAh, which should be converted according to the use voltage of 3.7V, so don't be surprised. The white T-shaped element below is a built-in loudspeaker. It can be seen that the position of the tripod cannot be adjusted backward due to the size of the battery.

We continue to disassemble and separate the light machine. The volume of the current light machine with LED light source has changed dramatically. The effect of adjusting the focusing lens is shown in the following figure:

The optical model of Q6 flagship (New) is OPD01, and on the side is Huabang Electronics W25Q16DVIG 16M bit FLASH memory chip.

The cooling fan is RFB3004 ultra-thin side outlet fan newly developed by RISUN (Taiwan Hongjin), which effectively ensures the cooling effect of light source devices.

With a large collection of internal components, you can see that the other side of the motherboard is integrated with multiple ICs, and the role of the main IC components of the motherboard will be explained separately later.

On the front of the motherboard, the video control chip and the WIFI+Bluetooth 4.0 module are mainly integrated.

Chip 1 is macro core T113AI (video switching/video control/OSD chip). T113AI is a highly integrated visual processor with built-in high-performance+1.8V LDO, triple ADC, TCON， 24 bit TTL, single/dual LVDS serial RGB output. The T113AI also integrates an enhanced two-layer OSD engine that supports smooth scaling and projector ladder correction. That is to say, the Q6 flagship (New) projector can achieve image zoom and trapezoid correction functions.

Chip 2 is the Ampak (positive base) AP6330 dual band module, which supports 2.4G and 5G dual band WIFI, Bluetooth BT4.0 and FM, etc. The WiFi 1T1R speed reaches 72.2Mbps, which can ensure the video playback traffic when using WIFI to connect to the network.

The chip 3 is Hong Kong KH25L3206E, which is a standard serial interface 4M flash memory with a working voltage of 2.7-3.6V, and can be erased up to 100000 times.

There are many chips integrated on the back of the motherboard. Chip 1 is Morningstar Semiconductor (MStar) MST6M182VG-LF-Z1. The core technology team of Morningstar Semiconductor is from TI (Texas Instruments), MST6M182VG-LF-Z1 is a highly integrated IC. In addition to integrating CPU, SCALER and TV DECODER, it also includes many powerful functions such as analog TV demod and intermediate playback, sound effect processing DSP, multimedia codec, and supports 1 channel HDMI1.3 and 2 channels USB2.0. The CPU is a 32-bit MIPS architecture, which supports ISP (programmable in the system) function and USB upgrade function. USB interface supports a variety of USB storage devices such as USB flash disk and mobile hard disk, and can play a variety of video, audio, pictures, and text content on USB storage devices through the built-in powerful multimedia codec. Video playback supports 720P MPEG2, RV8/9/10, RA8-LBR and HE-AAC decoding, H.264 reaching 1080P format. Audio playback supports multiple digital audio formats such as MPGE/1, MPGE/2, MP3, WMA, and AAC-LC. Pictures support JPEG BMP、PNG。 Text supports TXT. In addition, the hard disk supports FAT32 and NTFS. It can be seen from the chip data that USB can support hard disk, but it is actually unavailable, which may be related to battery drive.

Chip 2 is SK hynix H27UCG8T2BTR-BC memory chip, which is also known as modern memory. Q6 flagship (New) uses 8G memory.

Chip 3 is the famous Ruixin micro RK3128 chip. Ruixin micro RK3128 chip is a four core chip based on A7 architecture, integrating the performance of Mali GPU image accelerator, and can decode 1080P H.265 code.

Chip 7 is Texas Instruments (TI) DPP2607, a low-power DLP digital controller for battery powered display applications. This controller executes. 3 WVGA 24 VGA and. 2 nHD DMDs support the necessary image processing and display controls. The DPP2607 performs all necessary image processing and display control supporting 0.3 WVGA (853 x480 equivalent).

After the above detailed understanding of the motherboard chip, we have a "core" understanding of the functions and various supported interfaces of the Q6 flagship (New) mini projector. Especially when I just removed the motherboard and saw that the battery label capacity was 2500mAh, I still expressed doubts about the official data. When I saw that the battery voltage was 7.4V, it should be that the polymer lithium battery pack was used to make the projection volume smaller, that is, two 3.7V lithium batteries were connected in series, which converted to just 50000mAh.

The biggest advantage of Kuletv Q6 flagship (New) mini projection is that it is portable, and supports mobile phone wireless connection. Its optimal projection size is 60 inches. If it is larger, the image quality will be significantly reduced. If you only want to enjoy the experience of watching videos and audio anywhere when you go out, there is no doubt that Kuletv is your first choice. Of course, if you want to pursue the highest quality picture quality and also want to use it in the daytime, it is recommended to choose the S3 flagship version of Kule Sky Screen Cinema. Its brightness exceeds 1000 lumens, which is enough for you to enjoy the shock of super large screen audio and video in the daytime.
