The user experience of Tesla’s electric cars is centered mostly on the vehicles’ large, high-resolution displays. Coupled with custom software that provides a quick, smartphone-like experience, Tesla’s screens in its vehicles are already among the best in the auto industry. But in the spirit of the company’s habit of constant innovation, it appears that Tesla is looking to improve the quality of its displays even more. 

A recently published patent from the electric car maker, titled “Holographic Decorated Glass for Screen Color Matching,” outlines a way for the electric car maker to improve the viewing angles of its vehicles’ displays. In the patent, Tesla notes that “because display screens typically have a periodic micro-structure (e.g., a pixelated structure), the color of the display screen may be dependent on the angle at which a viewer is looking at the display screen.” This results in viewing angles that have significant room for improvement, even among high-quality screens. 

“The non-displaying portions of the device may be unable to match this angular color dependence of the display screen, resulting in a readily visible boundary between the display screen and the non-displaying portions of the device. Accordingly, there is a need for better color integration between the displaying portions of a device and the non-displaying portions of the device,” Tesla wrote.

To address this, Tesla opted to utilize a pigmented frame and index match glue to coat its vehicles’ screens, as well as a holographic glass panel. By adopting these techniques, Tesla expects to provide its vehicles with a screen that can offer optimal viewing angles for all passengers. This is especially useful when paired with the company’s entertainment features such as Tesla Theater or Tesla Arcade, which are accessible when a vehicle is on Park. 

Tesla describes its use of index match glue and holographic glass panels as follows.

“Index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of surrounding frame 202 within a small range of viewing angles. For example, index match glue 206 may change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a range of viewing angles approximately normal to the surface of display 204. However, due to the angular dependence of the perceived color and appearance of display 204 (due to display 204 having a holographic structure resulting from the pixels of display 204), index match glue 206 may be unable to change the perceived color and appearance of display 204 to match the color and appearance of frame 202 within a broad range of viewing angles so that the boundary between frame 202 and display 204 is invisible to a viewer. Accordingly, with display 204 coated with index match glue 206 surrounded by frame 202, the boundary between frame 202 and display 204 may still be readily visible at certain viewing angles.”

“The directionality of the periodic structure of holographic film 402 may approximate or match the directionality of the periodic structure of display 406. For example, if display 406 includes a plurality of periodic features (e.g., pixels) oriented in a first direction (e.g., rectangles, triangles, or the like having a common orientation), holographic film 402 may include a plurality of periodic features oriented in the first direction. FIG. 5 shows exemplary system 500 in which the visibility of a boundary between display 504 and a surrounding frame including a holographic structure (here holographic glass panel 502) may be reduced or eliminated over a broad range of viewing angles. In exemplary system 500, a periodic structure is formed on holographic glass panel 502 directly. For example, laser etching on holographic glass panel 502 may produce the periodic structure responsible for the holographic effect of holographic glass panel 502. Holographic glass panel 502 may include holographic structures formed in a variety of other ways, including ablation, etching, deposition processes, and the like.”

A color-matched display with optimal viewing angles might be a rather minor aspect of a vehicle, but for connected cars such as Teslas, it is these little things that make a difference in user experience. A car that boasts some of the most advanced automotive tech available in the auto segment today, after all, deserves a screen that is on par with some of the best mobile devices on the market.

Tesla’s display design outlined in its recently published patent can come in handy as well, particularly as the electric car maker introduces more updates to its fleet of vehicles. Among these is a “Fade Mode,” which Elon Musk has hinted at in the past. While responding to a Twitter follower last year, Musk responded positively to the suggestion of adding an option that allows drivers to dim their vehicles’ display while a car is in motion. This, together with features like V10’s Joe Mode, could help make long trips in Tesla’s electric vehicles much more convenient for passengers.

Elon Musk reiterates Tesla Optimus’ most sci-fi potential yet

Elon Musk recently reiterated one of the most ambitious forecasts for Tesla’s humanoid robot, Optimus, stating it could become the first real-world example of a Von Neumann machine. He also noted once more that Optimus would be Tesla’s biggest product.

Musk shared his comments in a series of posts on social media platform X.

Optimus as a von Neumann machine

In response to a post on X that pondered on sci-fi timelines becoming real, Musk wrote that “Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet.” In a separate post, Musk wrote that Optimus will be Tesla’s “biggest product ever,” a phrase he has used in the past to describe the humanoid robot’s importance to the electric vehicle maker.

A Von Neumann machine is a class of theoretical self-replicating systems originally proposed in the mid-20th century by the mathematician John von Neumann. In his concept, von Neumann described machines that could travel to other worlds, use local materials to create copies of themselves, and carry out large-scale tasks without outside intervention.

Elon Musk’s broader plans

Considering Musk’s comments, it appears that Optimus would eventually be capable of performing complex work autonomously in environments beyond Earth. If Optimus could achieve such a feat, it could very well unlock humanity’s capability to explore locations beyond Earth. The idea of space exploration becomes more than feasible.

Elon Musk has discussed space-based AI compute, large-scale robotic production, and the role of SpaceX’s Starship in transporting hardware and materials to other planets. While Musk did not detail how Optimus would fit with SpaceX’s exploration activities, his Von Neumann machine comments suggest he is looking at Tesla’s robotics as part of a potential interplanetary ecosystem.

Tesla China reported January wholesale sales of 69,129 Giga Shanghai-made vehicles, as per data released by the China Passenger Car Association (CPCA). The figure includes both domestic sales and exports from Gigafactory Shanghai.

The total represented a 9.32% increase from January last year but a 28.86% decline from December’s 97,171 units.

China EV market trends

The CPCA estimated that China’s passenger new energy vehicle wholesale volume reached about 900,000 units in January, up 1% year-on-year but down 42% from December. Demand has been pressured by the start-of-year slow season, a 5% additional purchase tax cost, and uncertainty around the transition of vehicle trade-in subsidies, as noted in a report from CNEV Post.

Market leader BYD sold 210,051 NEVs in January, down 30.11% year-on-year and 50.04% month-on-month, as per data released on February 1. Tesla China’s year-over-year growth then is quite interesting, as the company’s vehicles seem to be selling very well despite headwinds in the market.

Tesla China’s strategies

To counter weaker seasonal demand, Tesla China launched a low-interest financing program on January 6, offering up to seven-year terms on select produced vehicles. The move marked the first time an automaker offered financing of that length in the Chinese market.

Several rivals, including Xiaomi, Li Auto, XPeng, and NIO, later introduced similar incentives. Tesla China then further increased promotions on January 26 by reinstating insurance subsidies for the Model 3 sedan. The CPCA is expected to release Tesla’s China retail sales and export breakdown later this month.

Tesla’s Apple CarPlay ambitions are not dead, they’re still in the works

For what it’s worth, as a Tesla owner, I don’t particularly see the need for CarPlay, as I have found the in-car system that the company has developed to be superior. However, many people are in love with CarPlay simply because, when it’s in a car that is capable, it is really great.

Tesla’s Apple CarPlay ambitions appeared to be dead in the water after a large amount of speculation late last year that the company would add the user interface seemed to cool down after several weeks of reports.

However, it appears that CarPlay might make its way to Tesla vehicles after all, as a recent report seems to indicate that it is still being worked on by software teams for the company.

The real question is whether it is truly needed or if it is just a want by so many owners that Tesla is listening and deciding to proceed with its development.

Back in NovemberBloomberg reported that Tesla was in the process of testing Apple CarPlay within its vehicles, which was a major development considering the company had resisted adopting UIs outside of its own for many years.

Nearly one-third of car buyers considered the lack of CarPlay as a deal-breaker when buying their cars, a study from McKinsey & Co. outlined. This could be a driving decision in Tesla’s inability to abandon the development of CarPlay in its vehicles, especially as it lost a major advantage that appealed to consumers last year: the $7,500 EV tax credit.

Tesla owners propose interesting theory about Apple CarPlay and EV tax credit

Although we saw little to no movement on it since the November speculation, Tesla is now reportedly in the process of still developing the user interface. Mark Gurman, a Bloomberg writer with a weekly newsletter, stated that CarPlay is “still in the works” at Tesla and that more concrete information will be available “soon” regarding its development.

While Tesla already has a very capable and widely accepted user interface, CarPlay would still be an advantage, considering many people have used it in their vehicles for years. Just like smartphones, many people get comfortable with an operating system or style and are resistant to using a new one. This could be a big reason for Tesla attempting to get it in their own cars.

Tesla gets updated “Apple CarPlay” hack that can work on new models

For what it’s worth, as a Tesla owner, I don’t particularly see the need for CarPlay, as I have found the in-car system that the company has developed to be superior. However, many people are in love with CarPlay simply because, when it’s in a car that is capable, it is really great.

It holds one distinct advantage over Tesla’s UI in my opinion, and that’s the ability to read and respond to text messages, which is something that is available within a Tesla, but is not as user-friendly.

With that being said, I would still give CarPlay a shot in my Tesla. I didn’t particularly enjoy it in my Bronco Sport, but that was because Ford’s software was a bit laggy with it. If it were as smooth as Tesla’s UI, which I think it would be, it could be a really great addition to the vehicle.
