4 inch TFT screen + fast image loading

I have a 4-inch TFT screen (aliexpress, and I want to load images very fast.

I'm using LCDWIKI_KBV+LCDWIKI_GUI libraries.

Help?

#include <Wire.h> // Include the Wire library for I2C communication
#include <LiquidCrystal_I2C.h> // Include LCD library
#include <SoftwareSerial.h> // Include SoftwareSerial library for speech recognition module

#define SPEECH_RX_PIN 2 // Speech Recognition Module RX pin (connects to Arduino TX pin)
#define SPEECH_TX_PIN 3 // Speech Recognition Module TX pin (connects to Arduino RX pin)
#define VIBRATOR_PIN 5
#define IR_SENSOR_PIN 8

SoftwareSerial mySerial(2, 3); // RX, TX pins for speech recognition module
LiquidCrystal_I2C lcd(0x27, 16, 2); // Set the LCD I2C address to 0x27

unsigned long lastSeenTime = 0;
const unsigned long eyeContactDuration = 60000; // 1 minute in milliseconds

void setup() {
// Initialize serial communication with speech recognition module
mySerial.begin(9600);

// Initialize LCD display
lcd.init();
lcd.backlight();
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Listening...");

// Initialize IR sensor pin
pinMode(IR_SENSOR_PIN, INPUT);
// Initialize vibrator pin
pinMode(VIBRATOR_PIN, OUTPUT);

// Wait for the speech recognition module to start
delay(500);
}

void loop() {
// Check if the user is making eye contact
if (digitalRead(IR_SENSOR_PIN) == LOW) {
lastSeenTime = millis();
} else {
// If the user is not making eye contact for 1 minute, vibrate
if (millis() - lastSeenTime >= eyeContactDuration) {
digitalWrite(VIBRATOR_PIN, HIGH);
delay(1000); // Vibrate for 1 second
digitalWrite(VIBRATOR_PIN, LOW);
}
}

// Check if there is data available from the speech recognition module
if (mySerial.available() > 0) {
// Read the incoming byte
char receivedByte = mySerial.read();

// If the received byte is not noise (e.g., a spoken word)
if (receivedByte != ' ') {
  // Display the received byte on the LCD
  lcd.clear();
  lcd.setCursor(0, 0);
  lcd.print("Spoken: ");
  lcd.setCursor(0, 1);
  lcd.print(receivedByte);
}

}
}

Please check out the code if it is okey to execute sonicsee, the aim is that when lecturer explains to the audience and some who are having hearing issues the command will be able to signal and explain to them very well

it's a tft, not an lcd
