TFT IPS- High quality liquid crystal matrix. It has wide viewing angles, one of the best indicators of color rendering quality and contrast among all those used in the production of displays for portable equipment.
Super AMOLED- if a regular AMOLED screen uses several layers, between which there is an air gap, then in Super AMOLED there is only one such touch layer without air gaps. This allows you to achieve greater screen brightness with the same power consumption.
Super AMOLED HD- differs from Super AMOLED in its higher resolution, thanks to which you can achieve 1280x720 pixels on a mobile phone screen.
Super AMOLED plus- this is a new generation of Super AMOLED displays, differs from the previous one by using a larger number of subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than displays made using the old PenTile technology.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display a larger color gamut, reduced thickness and the ability of the display to bend slightly without the risk of breaking.
Retina-high pixel density display designed specifically for Apple technology. The pixel density of Retina displays is such that individual pixels are indistinguishable to the eye at a normal distance from the screen. This ensures the highest image detail and significantly improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast reaches 1,000,000:1. The display has a wide color gamut and unsurpassed color accuracy. Pixels in the corners of the display are smoothed at the sub-pixel level, so edges are not distorted and appear smooth. The Super Retina HD reinforcing layer is 50% thicker. It will be harder to break the screen.
Super LCD is the next generation of LCD technology, it is characterized by improved characteristics compared to earlier LCD displays. The screens not only have wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal display. Using an active matrix controlled by thin-film transistors, it is possible to significantly increase the performance of the display, as well as the contrast and clarity of the image.
OLED- organic electroluminescent display. It consists of a special thin-film polymer that emits light when exposed to an electric field. This type of display has a large reserve of brightness and consumes very little energy.
General characteristics
Type
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

They have not been on sale for a long time, but the company remembers its past achievements and this year decided to strike a stylish direction with the L-Style line. The younger model is called LG Optimus L3 (E400) and it is this model that will be discussed in this review.
LG Optimus L3 E400: Simplicity in details
A few months ago, LG Optimus L3 (E400) was presented at MWC 2012 and is already on sale here. You are unlikely to find any enthusiastic reviews or exclamations about it, but there are no complaints either. This dialer will be of interest to those who need a compact, inexpensive, stylish, fairly fast touch device. The price is very attractive - at the moment the new product costs approximately 1400 UAH. And what the client receives is fully consistent with the cost.
Review of UMTS/GSM phone LG Optimus L3 (E400)
As part of the international exhibition Mobile World Congress in 2012, the South Korean company LG presented three smartphones in the “Optimus L” line: L3, L5 and L7. The L3 smartphone belongs to the category of the lower price level and at the moment its cost is about 5,000 - 5,500 rubles. The technical characteristics of the device are quite ordinary: a small 3.2-inch screen with a resolution of 240x320 pixels, a 3-megapixel camera, wireless technologies (Bluetooth, Wi-Fi, GPS) and 384 MB of RAM.
Beauty requires sacrifice: review of the LG Optimus L3 (E400) smartphone
The LG Optimus L3 smartphone was presented two months ago at MWC 2012 along with two other models. First impressions of him were not so great. Cheap materials and too weak technical characteristics (perhaps this is the only Android smartphone of 2012 with a display resolution of 320x240, not counting some Chinese, of course) cannot be saved even by the modest price of one and a half thousand hryvnia, at which it can be bought today. But let's take a closer look at what this model is capable of and what and who it will have to compete with this spring.

He was not so great. Cheap materials and too weak technical characteristics (perhaps this is the only Android smartphone of 2012 with a display resolution of 320x240, not counting some Chinese, of course) cannot be saved even by the modest price of one and a half thousand hryvnia, at which it can be bought today. But let's take a closer look at what this model is capable of and what and who it will have to compete with this spring.
Specifications LG Optimus L3 (E400)
In my copy (this was not a store sample, although I don’t think there will be any significant difference in commercial smartphones), the LG Optimus L3 uses, according to benchmarks, 300 megabytes of RAM, 150 megabytes of internal memory, and there is also a gigabyte drive that is completely available to the user. Android version 2.3.6, of course, does not shine with novelty, but, apparently, the buyer will have to stop there - the device simply does not have the resources for further updates. Experimentally, we can establish that there is a Qualcomm MSM7625A processor inside (one of the benchmarks shows the processor as MSM7x25A, MSM7225A and MSM7625A fall under this definition, but the first has a frequency of 600 MHz). The battery capacity, however, is quite consistent with modern, and not two-year-old, ideas about this issue. And this is, perhaps, the only component of the system (well, maybe also the processor, which, although cheap, is relatively new) on which they did not save.
Appearance of LG Optimus L3 (E400)
In the two months that have passed since our first acquaintance, the device has not changed at all. It has an open and yet attractive appearance, which is spoiled only by the screen with extremely poor viewing angles and cheap materials.
From the back, the smartphone also looks original and recognizable. The lid has a corrugated texture. It seems that the Samsung Galaxy SII started the fashion for such things. This photo shows a paired volume control key, the plastic of which no one even tried to disguise.
The controls are extremely simple - there is an open microUSB port on the bottom, a headphone jack and a power button on top. The top view reminded me of the PRADA model (LG P940). There the lid also protrudes, creating the illusion of a thinner case than it actually is.
Below the display there are three keys - the central (menu) hardware key, and the pair on either side of it are touch keys. They are hidden and “appear” only when the backlight is turned on. Once upon a time in 2005 (?) the image model Chocolate had a similar solution and became its distinctive feature. 7 years later, this opportunity appears in the budget smartphone model.
The battery capacity is 1500 mAh, but what to spend it on when the capabilities of the smartphone are so limited is not entirely clear. However, you certainly can’t call this a disadvantage, even if you want to.
The memory card can be removed without turning off the phone; just remove the cover - the card compartment is located on the side panel. Pay attention to the camera lens - there is a glass plate glued to it, which protects the lens from dust. It is not possible to turn the camera eye into a traditional dust collector on this phone.
To compare sizes, I only had the new LG T370 touchscreen phone at hand (its review is also just around the corner).
Video review of LG Optimus L3 (E400)
The most important impressions of the appearance of the device can be seen in this video:
Performance LG Optimus L3 (E400)
Of course, with such characteristics it is foolish to expect miracles - in AnTuTu Optimus L3 scored 2194 points (this is less than the Sony Ericsson XPERIA X10 two years ago, although it is also not entirely correct to compare with a flagship device, albeit an old one). The device supports 5-point multi-touch, which characterizes it on the good side. And the benchmark for the Vellamo browser shows a modest score of 672 points. Although for a device running Android 2.3 with a screen resolution of 320x240, these are quite good indicators.
For the sake of this occasion, I had to pull out the good old Neocore and Quadrant Standard benchmarks from the dusty chest. In the first, LG Optimus L3 produced a confident 61 frames per second, in the second - 1230 points, which corresponds to the level of the Samsung Nexus S with Android 2.3.
The LG Optimus L3 browser comes standard with Android 2.3. That is, he can copy text and play video. True, YouTube videos open in a separate application, and not on a web page. But in general it must be said that in 2012 you can view websites at a resolution of 320x240 only from the extreme burning pain in the anus necessary. And the only thing you want when regularly viewing sites at this resolution is to quickly buy a smartphone with a higher resolution, and at the same time a screen diagonal.
A natural advantage of the low display resolution, its corresponding power consumption and weak processor is the relatively high battery life of the smartphone. At the same time, the 800-MHz processor easily copes with unconverted video. Of course, we are not talking about “real” HD, but a gigabyte file with a resolution of 624x352 with a film lasting an hour and a half was easy to move around. And it navigates through the video almost without pauses, even in a standard out-of-the-box player. Not to mention such “happiness” as 7 hours of operation from a charged battery when playing video.
Camera LG Optimus L3 (E400)
The camera is perhaps the weakest point of this smartphone. If you can put up with the rest of the technical capabilities (or understand that this is a compromise between a low price and a nice appearance), then the camera throws us back several years, to the times of extremely weak cameras built into phones. At the same time, video shooting (taking into account the modest capabilities of the sensor, of course) looks relatively decent with its VGA resolution. That is, if you evaluate the camera according to the Soviet school system, then the camera gets a C with a minus, and the video camera gets a solid B. Within the limits of your permissions, of course. However, everyone can evaluate the photo themselves.
Bottom line
As you might expect, the LG Optimus L3 smartphone looks more like a beautiful toy than a modern phone. Of course, this is the prettiest smartphone priced at 1,500 hryvnia, but the use of cheap materials can play a cruel joke on the buyer (or rather the buyer). If (when) all this is wiped off, the phone will turn from cute to completely unkempt. The situation is aggravated by a screen with extremely small viewing angles and a camera that is completely disgusting in its capabilities. At the same time, the device allows you to easily watch unconverted video and shoot video of satisfactory quality. In general, we have a rather nice phone with limited smartphone capabilities that can satisfy only a very unpretentious user who does not plan to use games more complex than Angry Birds, and uses the Internet on the phone once a week at best. 3 reasons to buy LG Optimus L3 (E400):
- beautiful appearance;
- ability to watch unconverted video;
- high battery capacity, which has nowhere to waste.
4 reasons not to buy LG Optimus L3 (E400):
- extremely poor screen viewing angles;
- mediocre camera without autofocus and backlight;
- cheap body materials;
- for 1,500 hryvnia you can buy a more interesting smartphone, although not as beautiful.
