Adhering to the business philosophy of “Quality, Persistence and Innovationâ€, Shenzhen Qipu Optoelectronics Co., Ltd. has quickly followed the development of the industry. Its high-end display RGB uses all the LEDs of Jingyuan Optoelectronics. After evaluation, Qipu Optoelectronics Co., Ltd. believes that pure screen made of pure core has the following unique advantages (only in Taiwan Jingyuan photoelectric pure core configuration):
1 , high brand value
As one of the largest chip manufacturers in Taiwan, Jingyuan Optoelectronics is an OEM of Japan's Nichia and American Cree, and is also a supplier of Apple's iPhone. Its quality is unmatched by other current mainland-made dies.
2, the performance price ratio is high
The brand influence of Jingyuan Optoelectronics is second only to two well-known manufacturers in Japan and the United States, and its product performance is very close to that of Japan and the United States, but the price is almost 1/4 of that of Japan and the United States. The use of wafer products, for customers, has a high performance price ratio.
3 , the wavelength is positive and the wavelength range is small
The crystal cells are all provided with positive wavelength products. The wavelength range is small, the color saturation is high after light distribution, the color is very positive, and white has a good effect. Even after long-term use, the RGB wavelength drifts when the attenuation is severe. Very small, thus maintaining a good color effect.
Basic parameters of illuminating die selection
| name | Die size | Wavelength nm | Brightness mcd | Die brand | Horizontal viewing angle | Vertical viewing angle |
| Pure red tube | 12*12mil | 620-624 | 1200-1450 | Taiwan wafer | 100-105 | 48-52 |
| Pure green tube | 8*15mil | 520-525 | 2500-3000 | Taiwan wafer | 100-105 | 48-52 |
| Pure blue tube | 9*12mil | 465-470 | 420-500 | Taiwan wafer | 100-105 | 48-52 |
4 , higher brightness
Generally, in the case of outdoor direct sunlight, the brightness of 6500mcd has already met the requirements. However, with the full-scale solution of Qipu Optoelectronics, it is easy to obtain brightness values ​​above 10000mcd.
The picture below shows the brightness contrast between the all-crystal series and the traditional product series:
| Types of | Point spacing | scanning method | Maximum brightness | Average brightness |
| Full crystal series | P10 | 1/4 | 11000cd/m2 | 8700cd/m2 |
| P16 | Static | 16500cd/m2 | 13500cd/m2 | |
| P20 | Static | 11000cd/m2 | 8700cd/m2 | |
| Traditional product series | P10 | 1/4 | 8300cd/m2 | 6500cd/m2 |
| P16 | Static | 13000cd/m2 | 10000cd/m2 | |
| P20 | Static | 9300cd/m2 | 6500cd/m2 |
5 , less current
Qipu Optoelectronics uses a smaller current to meet the brightness requirements of the display and ambient brightness, refer to the following table:
| Red, green and blue die | Ordinary die current | Chip die current |
| R red light | 14mA | 12mA |
| G green light | 13mA | 11mA |
| B blue light | 13mA | 11mA |
The advantages of small currents are obvious:
1) The calorific value is smaller, more energy-saving and environmentally friendly;
2) The light decay is slower, making the whole screen longer;
3) Switching power supply is used less, the cost of the whole screen accessory is lower, and it is more energy efficient.
This is the most competitive 15.6 inch Budget Business Laptop, comes with 2022 intel latest celeron cpu-N5095, J4125, etc . Of course, other Budget Working Laptop are also available.
For example, 15.6 inch i5 4th Budget Workstation Laptop for your mid-level task, 14 inch i5 10th Budget Laptop For 3d Modeling, 15.6 inch i7 5th Budget Laptop For Photoshop, or 15.6 inch i7 10th budget laptop for work, etc. Of course, there are other type device, like Android Tablet, 2 In 1 Laptop , Mini PC , All In One PC.
A thin, portable, light-performance laptop may be the ideal tool when people choose a business laptop, therefore just ask yourself 1.what jobs you mainly need this device to do, then choose the cpu and storage necessary, 2.if need fingerprint or backlight; 3. prefer type C charging? Or traditional DC is ok? 4. Does RJ45 webcam is important for you? 5. how many hours you need the laptop to work when do your main jobs?
6.Camera position, prefer on the middle of screen up? or is ok on the bottom of screen?
