According to official public information released by “Tencent Video†on January 5, during the recent New Year holiday, Tencent Video launched a campaign offering a 10% discount on its VIP membership. However, due to an unexpected server backend issue, some users experienced a strange situation on December 31, 2017—when they participated in the promotion, their monthly subscription was only deducted at a rate of 0.2 yuan instead of the regular price.
Netizens took to social media to express their surprise, with some joking that it felt like getting “ancestral VIP access.†Others expressed regret for not catching the deal in time, saying things like, “If I had known earlier, I would have filled up my Sansheng III.â€
While some users were confused or upset, others praised the company’s handling of the situation. One comment said, “This is exactly what a big company should do!†But what exactly happened here?
Following the incident, the official WeChat account of “Tencent Video VIP†issued a notice, advising affected members to check later and adding a friendly message: “Let’s have a good time in the new year.â€
So, how much did this error cost? Some might argue that the financial loss from such a small discrepancy isn’t huge—especially considering that Tencent is one of the “three pillars†of the tech industry. However, according to reports, the system glitch led to 2.87 million orders being processed at the wrong price, affecting around 390,000 users.
Even if we assume that each user only paid for a single year of membership, at the standard price of 198 yuan, the potential loss could be in the millions. And many users likely charged more than just one year. With 390,000 users involved, the damage could easily reach into the tens of millions, as reported by Techweb.
With over 43 million paid members, this bug affected nearly 1% of the user base. In the world of internet companies, even a small percentage can mean a large number of people. The company quickly addressed the issue, acknowledging the mistake and choosing to refund all affected users without hesitation.
Some users were worried that the company might start “recalling†the deals or even punishing the developers responsible. But rather than taking a harsh approach, the company chose to show empathy and generosity. As one user joked, “The programmer won’t get ‘hung’ for this.â€
Tencent’s response was clear: no matter how small or large the error, if it was caused by their own system, they would take full responsibility. This kind of honesty and accountability is rare among companies. A quick search for terms like “Promotion errors†or “Sales mistakes†shows how often similar issues occur, but few companies handle them with such transparency and goodwill.
In the business world, companies often have ways to reverse transactions—such as including clauses in promotions that allow them to cancel deals. But Tencent chose a different path: they accepted the mistake and made amends, showing trust and respect to their users. This kind of action not only preserves the company’s reputation but also strengthens customer loyalty.
At the heart of Tencent’s success lies a deep understanding of user value. With 43 million paid members, these users are more than just numbers—they are the foundation of Tencent Video’s growth and strategic importance. By prioritizing user experience and emotional connection, Tencent has built a brand that resonates with its audience.
Tencent Video also launched its “Good Times†brand story in late 2017, including an art installation called “Good Time Recording Museum†in Shanghai. Through these efforts, the company emphasizes content quality and user-centric values, reinforcing its position as a leader in the video streaming space.
True user engagement goes beyond just selling products—it's about building relationships. When problems arise, companies must choose between hiding or standing with their users. Tencent chose the latter, showing that it values trust and transparency over profit alone.
In the end, the way Tencent handled this situation proves that true user-centric platforms don’t shy away from mistakes—they learn from them, fix them, and grow stronger. It’s this kind of integrity that turns occasional errors into opportunities for deeper connection and loyalty.
TFT LCD Module
How does TFT work?
TFT is the abbreviation of "Thin Film Transistor", generally refers to thin film liquid crystal displays, but actually refers to thin film transistors (matrix)-can "actively" control each independent pixel on the screen, which is The origin of the so-called active matrix TFT (active matrix TFT). So how exactly is the image produced? The basic principle is very simple: the Display Screen is composed of many pixels that can emit light of any color, and the purpose can be achieved by controlling each pixel to display the corresponding color. In TFT LCD, backlight technology is generally used. In order to accurately control the color and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the "blinds" are opened, light can pass through, and " When the shutters are closed, light cannot pass through. Of course, technically, it is not as simple as the one just mentioned. LCD (Liquid Crystal Display) utilizes the characteristics of liquid crystals (liquid when heated, and crystallized into solid when cooled). Generally, liquid crystals have three forms:
Smectic liquid crystal similar to clay
Nematic liquid crystal resembling a fine matchstick
Cholestic liquid crystal
The liquid crystal display uses filaments, and when the external environment changes, its molecular structure will also change, and thus have different physical properties-it can achieve the purpose of letting light through or blocking light-which is just like the blinds just now.
Everyone knows the three primary colors, so each pixel on the display screen needs three similar basic components described above to control the three colors of red, green, and blue respectively.
The most commonly used one is twisted nematic TFT LCD (Twisted Nematic TFT LCD). Existing technologies vary greatly, and we will cover them in detail in the second part of this article.
There are grooves on the upper and lower layers. The grooves on the upper layer are arranged longitudinally and the grooves on the lower layer are arranged horizontally. When no voltage is applied to the liquid crystal in its natural state, the light emitted from the light emitting layer of the twisted nematic TFT Display working principle diagram of Figure 2a will be twisted by 90 degrees after passing through the interlayer, so that it can pass through the lower layer smoothly.
When a voltage is applied between the two layers, an electric field is generated. At this time, the liquid crystals are aligned vertically, so the light will not be twisted-the result is that the light cannot pass through the lower layer.
(2) TFT pixel structure: The color filter is divided into red, green, and blue according to the color, which are arranged on the glass substrate to form a group (dot pitch) corresponding to a pixel. Each monochromatic filter is called It is a sub-pixel. In other words, if a TFT display supports a maximum resolution of 1280×1024, then at least 1280×3×1024 sub-pixels and transistors are required. For a 15-inch TFT display (1024×768), then a pixel is about 0.0188 inches (equivalent to 0.30mm), for an 18.1-inch TFT display (1280×1024), it is 0.011 inches (equivalent to 0.28mm) .
As we all know, pixels are decisive for the display. The smaller each pixel is, the larger the maximum resolution that the display can achieve. However, due to the limitation of the physical characteristics of the transistor, the size of each pixel of the TFT at this stage is basically 0.0117 inches (0.297mm), so for a 15-inch display, the maximum resolution is only 1280×1024.
