Display
The presence of a
display controller in the design and the type of installed matrix.
The screen in remote controls for RC models can play different roles. Thus, it is possible to display a picture from the camera in real time on a color display, and service parameters are often superimposed on top of it (for example, flight altitude, speed, remaining battery charge level, all sorts of service notifications, etc.). Monochrome screens are usually assigned other tasks - first of all, they are responsible for tracking telemetry (for more details, see the corresponding paragraph).
It is customary to equip advanced controllers for RC models with a display. Simple remote controls are often presented
without a display. And according to the types of matrices, there are the following screen options in controllers:
-
OLED. In the context of control controllers, OLED screens usually mean the simplest solutions with a black backing and white symbols for displaying settings and/or various service information. Such displays are based on organic light-emitting diodes, and their key advantage is the ability to easily read the displayed information in poor ambient lighting.
-
LCD. As a rule, these are the simplest monochrome screens - either segmented to display a limited set of characters, or based on a single-color
...LCD matrix, suitable for text and basic graphic information. LCD screens provide additional convenience: they can display various important data, for example, the flight altitude of a conventional quadcopter, the speed of movement of the RC machine, the signal level, the remaining battery charge, notifications of problems, etc.
- TFT. A TFT display means a screen consisting not of segments, but of full pixels and suitable for displaying various types of data: graphic symbols, images, and even streaming video from an installed camera. TFT screens provide the most extensive visualization of settings; they are used in controllers for controlling drones and other RC models in FPV (First Person View) mode.Screen size
Display diagonal size in inches. The larger the display, the more accurate and easier to read the information displayed on it, the better the video stream can be seen on the screen in real time. On the other hand, a display that is too large entails an increase in the size and cost of the controller. In remote controls with the ability to display only service parameters, the screen size is usually from 1 to 3 inches, in copies with full color matrices and support for broadcasting a video stream - about 5 - 7 inches diagonally.
Screen resolution
Display size in dots (pixels) horizontally and vertically. The higher the resolution of the screen, the more detailed the image can be displayed on it and the smaller objects will be clearly visible. It makes sense to pay attention to this parameter in controllers that are used to control the RC model with a first-person view in real time. The display resolution of such copies can correspond to the
Full HD format (1920x1080 pixels) or even exceed it (for example,
Quad HD - 2560x1440 pixels).
Controls
The total number of controls in the remote control directly depends on the design, manufacturer, model and, most importantly, the purpose of the controller. This paragraph specifies all switches, buttons, sticks, sliders, scroll wheels and other elements used to control the RC model.
Touchscreen
The presence of
a touch display in the controller design.
Touch screens have a number of advantages over conventional ones. This display provides clearer and more convenient control than using buttons, analog levers or a traditional non-touch screen. Secondly, touchscreen displays are often quite large in size and can display not only banal symbols, but also full-color images. On the other hand, such equipment is not cheap, and the real need for it rarely arises - mainly for controlling the flights of advanced copters.
In the box
—
Cover/case. Case for storing and transporting the controller. Cases are called soft cases - they are designed mainly to protect against dirt. Cases are made of hard materials - they are more bulky, but they are able to protect the remote control from impacts and shocks.
—
Protection of gimbals/sticks. Protective covers or casings that cover the controller's control elements (in particular, sticks) and prevent them from being accidentally pressed. Such devices will come in handy for safely storing and carrying the remote control.
—
A set of springs for suspensions. These controller gimbal kits typically come with several different spring options, allowing you to select the appropriate control stiffness based on the user's individual preferences. This provides greater flexibility and the ability to customize the control panel to suit specific needs and conditions of use.
-
Protective glass. Glass or transparent film to protect the remote control screen from scratches, dirt and mechanical damage. Protective glasses are tasked with keeping the controller display in good condition. This is especially important on models with touchscreens or color TFT panels, where scratches or damage can negatively affect the quality of the information displayed.
