If you draw the same character in the same position with the same color as the background color, it will disappear.

// get font width & height
uint8_t buffer[FontxGlyphBufSize];
uint8_t fontWidth;
uint8_t fontHeight;
GetFontx(fx16G, 0, buffer, &fontWidth, &fontHeight);

lcdFillScreen(&dev, BLACK);
strcpy((char *)ascii, "WELCOME");
lcdDrawString(&dev, fx16G, xpos, ypos, ascii, WHITE);
vTaskDelay(1000);
strcpy((char *)ascii, "E");
lcdDrawString(&dev, fx16G, xpos+(fontWidth*1), ypos, ascii, BLACK);
lcdDrawString(&dev, fx16G, xpos+(fontWidth*6), ypos, ascii, BLACK);
strcpy((char *)ascii, "M");
lcdDrawString(&dev, fx16G, xpos+(fontWidth*5), ypos, ascii, BLACK);
