To use the seven-segment-specific TM1637, TM1638 and MAX7219 Display- commands, set DisplayMode to 0. Parameter LCD Display OLED Display TFT Display 7-segment Display (TM163x and MAX7219) 0 DisplayText DisplayText DisplayText All TM163x Display- functions

The DisplayText command is used to display text as well as graphics and graphs on LCD, OLED and e-Paper displays (EPD). The command argument is a string that is printed on the display at the current position. The string can be prefixed by embedded control commands enclosed in brackets [].

In order to use the DisplayText command the DisplayMode must be set to 0 (or optional 1 on LCD displays) or other modes must be disabled before compilation with #undef USE_DISPLAY_MODES1TO5.

While computers and web design are generally using a 24-bit RGB888 color code built from a byte-triplet such as (255, 136, 56) or #FF8038, small color panels often use a more compact code 16-bit RGB565 color code. This means that the R, G and B coefficient are coded on less number of bits: Red on 5 bits = 0..31

The EPD font contains 95 characters starting from code 32, while the classic GFX font contains 256 characters ranging from 0 to 255. Custom characters above 127 can be displayed. To display these characters, you must specify an escape sequence (standard octal escapes do not work). The ~character followed by a hex byte can define any character code.

All QMB Series displays feature reliable, non-glare panels that provide better visibility from all angles, any time of day. The non-glare display enables businesses to deliver accurate information in critical locations, such as airports and train stations.

• QNED MiniLED TVs: By combining NanoCell and miniLED technology, our QNED MiniLED televisions deliver brilliantly bright colors and a higher contrast ratio for deeper blacks. It"s the ultimate in LCD TVs.

The Samsung Q90/Q90T QLED and the LG C1 OLED are excellent TVs, but they use different panel types. The LG has an OLED panel with a near-infinite contrast because it can turn off individual pixels, and there"s no blooming around bright objects. It also has wider viewing angles and a quicker response time than the Samsung. On the other side, the Samsung gets much brighter because it has an LED panel, making it a better choice for well-lit rooms. Also, LED TVs appear to be immune to burn-in, unlike OLEDs.

The Samsung Q90/Q90T QLED and the Samsung Q80/Q80T QLED are very much alike, as they offer identical features. The biggest difference is in terms of performance, where the Q90T performs slightly better than the Q80T. The Q90T has a higher contrast ratio and peak brightness, and it has much better gradient performance, resulting in less banding. However, the Q80T has better color accuracy and black uniformity, although these could be due to panel variance.

The LG CX OLED is a better TV for most uses than the Samsung Q90T QLED, though the Q90Tstill performs excellent overall. The LG has perfect blacks thanks to its OLED panel and has excellent viewing angles and better motion handling. It also has much better gray uniformity and has a wider color gamut with more accurate colors out-of-the-box. On the other hand, the Samsung can get quite a bit brighter and has lower input lag. The Samsung also doesn"t run the risk of permanent image retention or burn-in, like the OLED panel on the LG does. This likely won"t be an issue for most OLED owners who watch normal, varied content, but can be a concern if you watch a ton of static images.

The Samsung Q90/Q90T QLED is higher in the Samsung lineup than the Samsung Q70/Q70T QLED, so it has much better performance. The Q90T has a local dimming feature, which the Q70T doesn"t, allowing it to display deeper blacks. The Q90T gets brighter and has wider viewing angles thanks to Samsung"s "Ultra Viewing Angle" layer as well. In terms of gaming, they each have a 120Hz panel and VRR support, but the Q90T has a much quicker response time.

The Samsung Q90/Q90T QLED and the LG GX OLED are both excellent premium TVs with different panel types. The LG uses an OLED panel that has an infinite contrast ratio, resulting in perfect blacks. It also has wider viewing angles than the Samsung and the response time is much quicker, resulting in smooth motion. On the other hand, the Samsung is a better choice for use in well-lit rooms or HDR content because it gets much brighter in both SDR and HDR. Also, the Samsung doesn"t have the risk of permanent burn-in like the LG.

The method of measuring screen size by its diagonal was inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, the external diameter of the bulb was used to describe their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the visible rectangle was smaller than the diameter of the tube due to the thickness of the glass surrounding the phosphor screen (which was hidden from the viewer by the casing and bezel). This method continued even when cathode ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3. In the US, when virtually all TV tubes were 4:3, the size of the screen was given as the true screen diagonal with a V following it (this was a requirement in the US market but not elsewhere). In virtually all other markets, the size of the outer diameter of the tube was given. What was a 27V in the US could be a 28" elsewhere. However the V terminology was frequently dropped in US advertising referring to a 27V as a 27". This was not misleading for the consumer as the seller had to give the actual screen size by law. Flat panel displays by contrast use the actual diagonal of their visible display size, thus the size is the actual size presented to the viewer in all markets. This means that a similarly specified size of display will be larger as a flat panel display compared with a cathode ray tube display.

Set sizes are frequently given as a "class" as screens from different manufacturers will have slight differences in size. However the "class" should be within 1/2" of the actual size. The reasons for the different sizes within a class stem from differences in the manufacturers" equipment. As manufacturers move from one size to another, newer larger sizes must fit on the same size glass, though with fewer displays being cut from it. Some sizes fit well and maximize glass utilization, other sizes fit more poorly and waste glass. As an example, in some cases, increasing the screen size by even 0.1" can cause an LCD manufacturer to go from 12 screens fitting on their glass sheet to 9. This would make them uncompetitive with other screen makers.
