The **10TS-050-R** is a specific part number typically associated with **resistive touch screens**. These components are widely used in industrial controls, medical devices, and consumer electronics to provide a user interface for LCD panels. Below is a detailed breakdown of its specifications, electronic structure, and functionality. --- ### 1. General Specifications The "050" in the part number usually indicates the diagonal size of the screen (5.0 inches). | Feature | Specification | | :--- | :--- | | **Type** | 4-Wire Resistive Touch Screen | | **Size** | 5.0 Inch (Diagonal) | | **Interface** | FPC (Flexible Printed Circuit) Cable | | **Transparency** | Typically > 75% | | **Input Method** | Finger, Stylus, or Gloved hand | | **Durability** | ~1 million touches in a single location | --- ### 2. Electronic Structure A resistive touch screen like the 10TS-050-R consists of several layers that act as a variable resistor: * **Top Layer:** A flexible polyester (PET) film with a transparent conductive coating (ITO - Indium Tin Oxide) on the bottom side. * **Bottom Layer:** A rigid glass substrate with a transparent conductive coating (ITO) on the top side. * **Spacer Dots:** Microscopic insulating dots that keep the two layers apart until pressed. * **The Circuit:** When a user presses the screen, the top flexible layer touches the bottom glass layer, completing a circuit at that specific point. --- ### 3. Pinout and Connection (4-Wire) The 10TS-050-R utilizes a 4-wire interface. To calculate the (X, Y) coordinates, the controller applies a voltage gradient across the layers. | Pin Name | Description | Function | | :--- | :--- | :--- | | **X+ (Right)** | Positive X electrode | Measures horizontal position | | **X- (Left)** | Negative X electrode | Measures horizontal position | | **Y+ (Top)** | Positive Y electrode | Measures vertical position | | **Y- (Bottom)** | Negative Y electrode | Measures vertical position | --- ### 4. Implementation Code Example To use this part with a microcontroller (like an Arduino or ESP32), you typically use an ADC (Analog-to-Digital Converter) to read the voltage at the touch point. ```cpp // Example: Basic logic for reading a 4-wire resistive touch screen const int YP = A0; // Must be analog const int XM = A1; // Must be analog const int YM = 7; const int XP = 8; void setup() { Serial.begin(9600); } void loop() { // Read X-coordinate pinMode(YP, INPUT); pinMode(YM, INPUT); pinMode(XP, OUTPUT); pinMode(XM, OUTPUT); digitalWrite(XP, HIGH); digitalWrite(XM, LOW); int xRaw = analogRead(YP); // Read Y-coordinate pinMode(XP, INPUT); pinMode(XM, INPUT); pinMode(YP, OUTPUT); pinMode(YM, OUTPUT); digitalWrite(YP, HIGH); digitalWrite(YM, LOW); int yRaw = analogRead(XP); Serial.print("X: "); Serial.print(xRaw); Serial.print(" | Y: "); Serial.println(yRaw); delay(100); } ``` --- ### 5. Key Advantages & Disadvantages * **Pros:** Low cost, can be used with gloves, highly resistant to dust and water droplets, simple electronic interface. * **Cons:** No multi-touch support (single touch only), lower clarity compared to capacitive screens, prone to scratching over time.
